-If the compilation fails when the agent tries to link the `libseccomp` library statically

-You can use [our script](https://github.com/kata-containers/kata-containers/blob/main/ci/install_libseccomp.sh)

-Docker supports the ability for containers to join another containers
-namespace with the `docker run --net=containers` syntax. This allows
-multiple containers to share a common network namespace and the network
-interfaces placed in the network namespace. Kata Containers does not
-support network namespace sharing. If a Kata Container is setup to

-effectively takes over all the network interfaces assigned to the
-namespace and binds them to the VM. Consequently, the `runc` container loses

-For systemd, kata agent configures cgroups according to the following `linux.cgroupsPath` format standard provided by `runc` (`[slice]:[prefix]:[name]`). If you don't provide a valid `linux.cgroupsPath`, kata agent will treat it as `"system.slice:kata_agent:<container-id>"`. 
-
-> Here slice is a systemd slice under which the container is placed. If empty, it defaults to system.slice, except when cgroup v2 is used and rootless container is created, in which case it defaults to user.slice.
->
-> Note that slice can contain dashes to denote a sub-slice (e.g. user-1000.slice is a correct notation, meaning a `subslice` of user.slice), but it must not contain slashes (e.g. user.slice/user-1000.slice is invalid).
->
-> A slice of `-` represents a root slice.
->
-> Next, prefix and name are used to compose the unit name, which is `<prefix>-<name>.scope`, unless name has `.slice` suffix, in which case prefix is ignored and the name is used as is.
-
-## supported properties
-
-The kata agent will translate the parameters in the `linux.resources` of `config.json` into systemd unit properties, and send it to systemd for configuration. Since systemd supports limited properties, only the following parameters in `linux.resources` will be applied. We will simply treat hybrid mode as legacy mode by the way.

-## Systemd Interface
-
-`session.rs` and `system.rs` in `src/agent/rustjail/src/cgroups/systemd/interface` are automatically generated by `zbus-xmlgen`, which is is an accompanying tool provided by `zbus` to generate Rust code from `D-Bus XML interface descriptions`. The specific commands to generate these two files are as follows: 
-
-```shell
-// system.rs
-zbus-xmlgen --system org.freedesktop.systemd1 /org/freedesktop/systemd1
-// session.rs
-zbus-xmlgen --session org.freedesktop.systemd1 /org/freedesktop/systemd1
-```
-
-The current implementation of `cgroups/systemd` uses `system.rs` while `session.rs` could be used to build rootless containers in the future.

-# Kata 3.0 Architecture
-## Overview
-In cloud-native scenarios, there is an increased demand for container startup speed, resource consumption, stability, and security, areas where the present Kata Containers runtime is challenged relative to other runtimes. To achieve this, we propose a solid, field-tested and secure Rust version of the kata-runtime.
-
-Also, we provide the following designs:
-
-- Turn key solution with builtin `Dragonball` Sandbox
-- Async I/O to reduce resource consumption
-- Extensible framework for multiple services, runtimes and hypervisors
-- Lifecycle management for sandbox and container associated resources
-
-### Rationale for choosing Rust
-
-We chose Rust because it is designed as a system language with a focus on efficiency.
-In contrast to Go, Rust makes a variety of design trade-offs in order to obtain
-good execution performance, with innovative techniques that, in contrast to C or
-C++, provide reasonable protection against common memory errors (buffer
-overflow, invalid pointers, range errors), error checking (ensuring errors are
-dealt with), thread safety, ownership of resources, and more.
-
-These benefits were verified in our project when the Kata Containers guest agent
-was rewritten in Rust. We notably saw a significant reduction in memory usage
-with the Rust-based implementation.
-
-
-## Design
-### Architecture
-![architecture](./images/architecture.png)
-### Built-in VMM
-#### Current Kata 2.x architecture
-![not_builtin_vmm](./images/not_built_in_vmm.png)
-As shown in the figure, runtime and VMM are separate processes. The runtime process forks the VMM process and interacts through the inter-process RPC. Typically, process interaction consumes more resources than peers within the process, and it will result in relatively low efficiency. At the same time, the cost of resource operation and maintenance should be considered. For example, when performing resource recovery under abnormal conditions, the exception of any process must be detected by others and activate the appropriate resource recovery process. If there are additional processes, the recovery becomes even more difficult.
-#### How To Support Built-in VMM
-We provide `Dragonball` Sandbox to enable built-in VMM by integrating VMM's function into the Rust library. We could perform VMM-related functionalities by using the library. Because runtime and VMM  are in the same process, there is a benefit in terms of message processing speed and API synchronization. It can also guarantee the consistency of the runtime and the VMM life cycle, reducing resource recovery and exception handling maintenance, as shown in the figure:
-![builtin_vmm](./images/built_in_vmm.png)
-### Async Support
-#### Why Need Async
-**Async is already in stable Rust and allows us to write async code**
-
-- Async provides significantly reduced CPU and memory overhead, especially for workloads with a large amount of IO-bound tasks
-- Async is zero-cost in Rust, which means that you only pay for what you use. Specifically, you can use async without heap allocations and dynamic dispatch, which greatly improves efficiency
-- For more (see [Why Async?](https://rust-lang.github.io/async-book/01_getting_started/02_why_async.html) and [The State of Asynchronous Rust](https://rust-lang.github.io/async-book/01_getting_started/03_state_of_async_rust.html)).
-
-**There may be several problems if implementing kata-runtime with Sync Rust**
-
-- Too many threads with a new TTRPC connection
-   - TTRPC threads: reaper thread(1) + listener thread(1) + client handler(2)
-- Add 3 I/O threads with a new container
-- In Sync mode, implementing a timeout mechanism is challenging. For example, in TTRPC API interaction, the timeout mechanism is difficult to align with Golang
-#### How To Support Async
-The kata-runtime is controlled by TOKIO_RUNTIME_WORKER_THREADS to run the OS thread, which is 2 threads by default. For TTRPC and container-related threads run in the `tokio` thread in a unified manner, and related dependencies need to be switched to Async, such as Timer, File, Netlink, etc. With the help of Async, we can easily support no-block I/O and timer. Currently, we only utilize Async for kata-runtime. The built-in VMM keeps the OS thread because it can ensure that the threads are controllable.
-
-**For N tokio worker threads and M containers**
-
-- Sync runtime(both OS thread and `tokio` task are OS thread but without `tokio` worker thread)  OS thread number:  4 + 12*M
-- Async runtime(only OS thread is OS thread) OS thread number: 2 + N
-```shell
-├─ main(OS thread)
-├─ async-logger(OS thread)
-└─ tokio worker(N * OS thread)
-  ├─ agent log forwarder(1 * tokio task)
-  ├─ health check thread(1 * tokio task)
-  ├─ TTRPC reaper thread(M * tokio task)
-  ├─ TTRPC listener thread(M * tokio task)
-  ├─ TTRPC client handler thread(7 * M * tokio task)
-  ├─ container stdin io thread(M * tokio task)
-  ├─ container stdout io thread(M * tokio task)
-  └─ container stderr io thread(M * tokio task)
-```
-### Extensible Framework
-The Kata 3.x runtime is designed with the extension of service, runtime, and hypervisor, combined with configuration to meet the needs of different scenarios. At present, the service provides a register mechanism to support multiple services. Services could interact with runtime through messages. In addition, the runtime handler handles messages from services. To meet the needs of a binary that supports multiple runtimes and hypervisors, the startup must obtain the runtime handler type and hypervisor type through configuration.
-
-![framework](./images/framework.png)
-### Resource Manager
-In our case, there will be a variety of resources, and every resource has several subtypes. Especially for `Virt-Container`, every subtype of resource has different operations. And there may be dependencies, such as the share-fs rootfs and the share-fs volume will use share-fs resources to share files to the VM. Currently, network and share-fs are regarded as sandbox resources, while rootfs, volume, and cgroup are regarded as container resources. Also, we abstract a common interface for each resource and use subclass operations to evaluate the differences between different subtypes.

-## FAQ
-
-- Are the "service", "message dispatcher" and "runtime handler" all part of the single Kata 3.x runtime binary?
-
-  Yes. They are components in Kata 3.x runtime. And they will be packed into one binary.
-  1. Service is an interface, which is responsible for handling multiple services like task service, image service and etc. 
-  2. Message dispatcher, it is used to match multiple requests from the service module. 
-  3. Runtime handler is used to deal with the operation for sandbox and container. 
-- What is the name of the Kata 3.x runtime binary?
-  
-  Apparently we can't use `containerd-shim-v2-kata` because it's already used. We are facing the hardest issue of "naming" again. Any suggestions are welcomed.
-  Internally we use `containerd-shim-v2-rund`.
-
-- Is the Kata 3.x design compatible with the containerd shimv2 architecture? 
-  
-  Yes. It is designed to follow the functionality of go version kata.  And it implements the `containerd shim v2` interface/protocol.
-
-- How will users migrate to the Kata 3.x architecture?
-  
-  The migration plan will be provided before the Kata 3.x is merging into the main branch.
-
-- Is `Dragonball` limited to its own built-in VMM? Can the `Dragonball` system be configured to work using an external `Dragonball` VMM/hypervisor?
-
-  The `Dragonball` could work as an external hypervisor. However, stability and performance is challenging in this case. Built in VMM could optimise the container overhead, and it's easy to maintain stability.
-
-  `runD` is the `containerd-shim-v2` counterpart of `runC` and can run a pod/containers. `Dragonball` is a `microvm`/VMM that is designed to run container workloads. Instead of `microvm`/VMM, we sometimes refer to it as secure sandbox.
-
-- QEMU, Cloud Hypervisor and Firecracker support are planned, but how that would work. Are they working in separate process?
- 
-  Yes. They are unable to work as built in VMM.
-
-- What is `upcall`?
-  
-    The `upcall` is used to hotplug CPU/memory/MMIO devices, and it solves two issues.
-    1. avoid dependency on PCI/ACPI
-    2. avoid dependency on `udevd` within guest and get deterministic results for hotplug operations. So `upcall` is an alternative to ACPI based CPU/memory/device hotplug. And we may cooperate with the community to add support for ACPI based CPU/memory/device hotplug if needed.
-   
-    `Dbs-upcall` is a `vsock-based` direct communication tool between VMM and guests. The server side of the `upcall` is a driver in guest kernel (kernel patches are needed for this feature) and it'll start to serve the requests once the kernel has started. And the client side is in VMM , it'll be a thread that communicates with VSOCK through `uds`. We have accomplished device hotplug / hot-unplug directly through `upcall` in order to avoid virtualization of ACPI  to minimize virtual machine's overhead. And there could be many other usage through this direct communication channel. It's already open source.
-   https://github.com/openanolis/dragonball-sandbox/tree/main/crates/dbs-upcall 
-
-- The URL below says the kernel patches work with 4.19, but do they also work with 5.15+ ?
-  
-  Forward compatibility should be achievable, we have ported it to 5.10 based kernel.
-
-- Are these patches platform-specific or would they work for any architecture that supports VSOCK?
-  
-  It's almost platform independent, but some message related to CPU hotplug are platform dependent.
-
-- Could the kernel driver be replaced with a userland daemon in the guest using loopback VSOCK?
-  
-  We need to create device nodes for hot-added CPU/memory/devices, so it's not easy for userspace daemon to do these tasks.
-
-- The fact that `upcall` allows communication between the VMM and the guest suggests that this architecture might be incompatible with https://github.com/confidential-containers where the VMM should have no knowledge of what happens inside the VM.
-  
-  1. `TDX` doesn't support CPU/memory hotplug yet.
-  2. For ACPI based device hotplug, it depends on ACPI `DSDT` table, and the guest kernel will execute `ASL` code to handle during handling those hotplug event. And it should be easier to audit VSOCK based communication than ACPI `ASL` methods.
-
-- What is the security boundary for the monolithic / "Built-in VMM" case?
-  
-  It has the security boundary of virtualization. More details will be provided in next stage.

-# Kata Containers support for `Hooks`
-
-## Introduction
-
-During container's lifecycle, different Hooks can be executed to do custom actions. In Kata Containers, we support two types of Hooks, `OCI Hooks` and `Kata Hooks`.
-
-### OCI Hooks
-
-The OCI Spec stipulates six hooks that can be executed at different time points and namespaces, including `Prestart Hooks`, `CreateRuntime Hooks`, `CreateContainer Hooks`, `StartContainer Hooks`, `Poststart Hooks` and `Poststop Hooks`. We support these types of Hooks as compatible as possible in Kata Containers.
-
-The path and arguments of these hooks will be passed to Kata for execution via `bundle/config.json`. For example:
-```
-...
-"hooks": {
-  "prestart": [
-    {
-      "path": "/usr/bin/prestart-hook",
-      "args": ["prestart-hook", "arg1", "arg2"],
-      "env":  [ "key1=value1"]
-    }
-  ],
-  "createRuntime": [
-    {
-      "path": "/usr/bin/createRuntime-hook",
-      "args": ["createRuntime-hook", "arg1", "arg2"],
-      "env":  [ "key1=value1"]
-    }
-  ]
-}
-...
-```
-
-### Kata Hooks
-
-In Kata, we support another three kinds of hooks executed in guest VM, including `Guest Prestart Hook`, `Guest Poststart Hook`, `Guest Poststop Hook`.
-
-The executable files for Kata Hooks must be packaged in the *guest rootfs*. The file path to those guest hooks should be specified in the configuration file, and guest hooks must be stored in a subdirectory of `guest_hook_path` according to their hook type. For example:
-
-+ In configuration file:
-```
-guest_hook_path="/usr/share/hooks"
-```
-+ In guest rootfs, prestart-hook is stored in `/usr/share/hooks/prestart/prestart-hook`.
-
-## Execution
-The table below summarized when and where those different hooks will be executed in Kata Containers:
-
-| Hook Name | Hook Type | Hook Path | Exec Place | Exec Time |
-|---|---|---|---|---|
-| `Prestart(deprecated)` | OCI hook | host runtime namespace | host runtime namespace | After VM is started, before container is created. |
-| `CreateRuntime` | OCI hook | host runtime namespace | host runtime namespace | After VM is started, before container is created, after `Prestart` hooks. |
-| `CreateContainer` | OCI hook | host runtime namespace | host vmm namespace* | After VM is started, before container is created, after `CreateRuntime` hooks. |
-| `StartContainer` | OCI hook | guest container namespace | guest container namespace | After container is created, before container is started. |
-| `Poststart` | OCI hook | host runtime namespace | host runtime namespace | After container is started, before start operation returns. |
-| `Poststop` | OCI hook | host runtime namespace | host runtime namespace | After container is deleted, before delete operation returns. |
-| `Guest Prestart` | Kata hook | guest agent namespace | guest agent namespace | During start operation, before container command is executed. |
-| `Guest Poststart` | Kata hook | guest agent namespace | guest agent namespace | During start operation, after container command is executed, before start operation returns. |
-| `Guest Poststop` | Kata hook | guest agent namespace | guest agent namespace | During delete operation, after container is deleted, before delete operation returns. |
-
-+ `Hook Path` specifies where hook's path be resolved.
-+ `Exec Place` specifies in which namespace those hooks can be executed.
-  + For `CreateContainer` Hooks, OCI requires to run them inside the container namespace while the hook executable path is in the host runtime, which is a non-starter for VM-based containers. So we design to keep them running in the *host vmm namespace.* 
-+ `Exec Time` specifies at which time point those hooks can be executed.

-# Design Doc for Kata Containers' VCPUs Pinning Feature
-
-## Background
-By now, vCPU threads of Kata Containers are scheduled randomly to CPUs. And each pod would request a specific set of CPUs which we call it CPU set (just the CPU set meaning in Linux cgroups).    
-
-If the number of vCPU threads are equal to that of CPUs claimed in CPU set, we can then pin each vCPU thread to one specified CPU, to reduce the cost of random scheduling. 
-
-## Detailed Design
-
-### Passing Config Parameters
-Two ways are provided to use this vCPU thread pinning feature: through `QEMU` configuration file and through annotations. Finally the pinning parameter is passed to `HypervisorConfig`.

-| Official Doc Page | https://pkg.go.dev/golang.org/x/sys/unix#SchedSetaffinity |
-
-### When is VCPUs Pinning Checked?
-
-As shown in Section 1, when `num(vCPU threads) == num(CPUs in CPU set)`, we shall pin each vCPU thread to a specified CPU. And when this condition is broken, we should restore to the original random scheduling pattern.  
-So when may `num(CPUs in CPU set)` change? There are 5 possible scenes:

-# How to build, run and test Kata CCv0
-
-## Introduction and Background
-
-In order to try and make building (locally) and demoing the Kata Containers `CCv0` code base as simple as possible I've
-shared a script [`ccv0.sh`](./ccv0.sh). This script was originally my attempt to automate the steps of the 
-[Developer Guide](https://github.com/kata-containers/kata-containers/blob/main/docs/Developer-Guide.md) so that I could do
-different sections of them repeatedly and reliably as I was playing around with make changes to different parts of the 
-Kata code base. I then tried to weave in some of the [`tests/.ci`](https://github.com/kata-containers/tests/tree/main/.ci) 
-scripts in order to have less duplicated code.
-As we're progress on the confidential containers journey I hope to add more features to demonstrate the functionality
-we have working.
-
-*Disclaimer: This script has mostly just been used and tested by me ([@stevenhorsman](https://github.com/stevenhorsman)),*
-*so there might be issues with it. I'm happy to try and help solve these if possible, but this shouldn't be considered a*
-*fully supported process by the Kata Containers community.*
-
-### Basic script set-up and optional environment variables
-
-In order to build, configure and demo the CCv0 functionality, these are the set-up steps I take:
-- Provision a new VM
-    - *I choose a Ubuntu 20.04 8GB VM for this as I had one available. There are some dependences on apt-get installed*
-    *packages, so these will need re-working to be compatible with other platforms.*
-- Copy the script over to your VM *(I put it in the home directory)* and ensure it has execute permission by running 
-```bash
-$ chmod u+x ccv0.sh
-```
-- Optionally set up some environment variables
-    - By default the script checks out the `CCv0` branches of the `kata-containers/kata-containers` and 
-      `kata-containers/tests` repositories, but it is designed to be used to test of personal forks and branches as well. 
-      If you want to build and run these you can export the `katacontainers_repo`, `katacontainers_branch`, `tests_repo`
-      and `tests_branch` variables e.g.
-      ```bash
-      $ export katacontainers_repo=github.com/stevenhorsman/kata-containers
-      $ export katacontainers_branch=stevenh/agent-pull-image-endpoint
-      $ export tests_repo=github.com/stevenhorsman/tests
-      $ export tests_branch=stevenh/add-ccv0-changes-to-build
-      ```
-      before running the script.
-    - By default the build and configuration are using `QEMU` as the hypervisor. In order to use `Cloud Hypervisor` instead
-      set:
-      ```
-      $ export KATA_HYPERVISOR="cloud-hypervisor"
-      ```
-      before running the build.
-
-- At this point you can provision a Kata confidential containers pod and container with either
-  [`crictl`](#using-crictl-for-end-to-end-provisioning-of-a-kata-confidential-containers-pod-with-an-unencrypted-image),
-  or [Kubernetes](#using-kubernetes-for-end-to-end-provisioning-of-a-kata-confidential-containers-pod-with-an-unencrypted-image)
-  and then test and use it. 
-
-### Using crictl for end-to-end provisioning of a Kata confidential containers pod with an unencrypted image
-
-- Run the full build process with Kubernetes turned off, so its configuration doesn't interfere with `crictl` using:
-  ```bash
-  $ export KUBERNETES="no"
-  $ export KATA_HYPERVISOR="qemu"
-  $ ~/ccv0.sh -d build_and_install_all
-  ```
-    > **Note**: Much of this script has to be run as `sudo`, so you are likely to get prompted for your password.
-    - *I run this script sourced just so that the required installed components are accessible on the `PATH` to the rest*
-      *of the process without having to reload the session.*
-    - The steps that `build_and_install_all` takes is:
-        - Checkout the git repos for the `tests` and `kata-containers` repos as specified by the environment variables
-        (default to `CCv0` branches if they are not supplied)
-        - Use the `tests/.ci` scripts to install the build dependencies
-        - Build and install the Kata runtime
-        - Configure Kata to use containerd and for debug and confidential containers features to be enabled (including
-          enabling console access to the Kata guest shell, which should only be done in development)
-        - Create, build and install a rootfs for the Kata hypervisor to use. For 'CCv0' this is currently based on Ubuntu
-        20.04.
-        - Build the Kata guest kernel
-        - Install the hypervisor (in order to select which hypervisor will be used, the `KATA_HYPERVISOR` environment
-        variable can be used to select between `qemu` or `cloud-hypervisor`)
-    > **Note**: Depending on how where your VMs are hosted and how IPs are shared you might get an error from docker
-    during matching `ERROR: toomanyrequests: Too Many Requests`. To get past
-    this, login into Docker Hub and pull the images used with:
-  >  ```bash
-  >  $ sudo docker login
-  >  $ sudo docker pull ubuntu
-  >  ```
-  >  then re-run the command.
-    - The first time this runs it may take a while, but subsequent runs will be quicker as more things are already
-      installed and they can be further cut down by not running all the above steps 
-      [see "Additional script usage" below](#additional-script-usage)
-   
-- Create a new Kata sandbox pod using `crictl` with:
-  ```bash
-  $ ~/ccv0.sh crictl_create_cc_pod
-  ```
-    - This creates a pod configuration file, creates the pod from this using 
-    `sudo crictl runp -r kata ~/pod-config.yaml` and runs `sudo crictl pods` to show the pod
-- Create a new Kata confidential container with:
-  ```bash
-  $ ~/ccv0.sh crictl_create_cc_container
-  ```
-    - This creates a container (based on `busybox:1.33.1`) in the Kata cc sandbox and prints a list of containers.
-      This will have been created based on an image pulled in the Kata pod sandbox/guest, not on the host machine.
-
-As this point you should have a `crictl` pod and container that is using the Kata confidential containers runtime.

-  >  ```
-  >  then re-run the command.
-- Check that your Kubernetes cluster has been correctly set-up by running :

-  ```
-  and checking that you see a single node e.g.
-  ```text
-  NAME                             STATUS   ROLES                  AGE   VERSION
-  stevenh-ccv0-k8s1.fyre.ibm.com   Ready    control-plane,master   43s   v1.22.0
-  ```
-- Create a Kata confidential containers pod by running:
-  ```bash
-  $ ~/ccv0.sh kubernetes_create_cc_pod
-  ```
-- Wait a few seconds for pod to start then check that the pod's status is `Running` with 
-  ```bash
-  $ kubectl get pods
-  ```
-  which should show something like:
-  ```text
-  NAME         READY   STATUS    RESTARTS   AGE
-  busybox-cc   1/1     Running   0          54s
-  ```
-
-- As this point you should have a Kubernetes pod and container running, that is using the Kata 
-confidential containers runtime.
-You can [validate that the container image was pulled on the guest](#validate-that-the-container-image-was-pulled-on-the-guest)
-or [using the Kata pod sandbox for testing with `agent-ctl` or `ctr shim`](#using-a-kata-pod-sandbox-for-testing-with-agent-ctl-or-ctr-shim)
-
-#### Clean up the Kubernetes pod sandbox and container
-- When the testing is complete you can delete the container and pod by running:
-  ```bash
-  $ ~/ccv0.sh kubernetes_delete_cc_pod
-  ```
-
-### Validate that the container image was pulled on the guest
-
-There are a couple of ways we can check that the container pull image action was offloaded to the guest, by checking
-the guest's file system for the unpacked bundle and checking the host's directories to ensure it wasn't also pulled
-there.
-- To check the guest's file system:
-    - Open a shell into the Kata guest with:
-      ```bash
-      $ ~/ccv0.sh open_kata_shell
-      ```
-    - List the files in the directory that the container image bundle should have been unpacked to with:
-      ```bash
-      $ ls -ltr /run/kata-containers/confidential-containers_signed/
-      ```
-    - This should give something like
-        ```
-        total 72
-        -rw-r--r--  1 root root  2977 Jan 20 10:03 config.json
-        drwxr-xr-x 12 root root   240 Jan 20 10:03 rootfs
-        ```
-        which shows how the image has been pulled and then unbundled on the guest.
-    - Leave the Kata guest shell by running:
-      ```bash
-      $ exit
-      ```
-- To verify that the image wasn't pulled on the host system we can look at the shared sandbox on the host and we
-  should only see a single bundle for the pause container as the `busybox` based container image should have been
-  pulled on the guest:
-    - Find all the `rootfs` directories under in the pod's shared directory with:
-      ```bash
-      $ pod_id=$(ps -ef | grep containerd-shim-kata-v2 | egrep -o "id [^,][^,].* " | awk '{print $2}')
-      $ sudo find /run/kata-containers/shared/sandboxes/${pod_id}/shared -name rootfs
-      ```
-      which should only show a single `rootfs` directory if the container image was pulled on the guest, not the host
-    - Looking that `rootfs` directory with
-      ```bash
-      $ sudo ls -ltr $(sudo find /run/kata-containers/shared/sandboxes/${pod_id}/shared -name rootfs)
-      ```
-      shows something similar to
-      ```
-      total 668
-      -rwxr-xr-x 1 root root 682696 Aug 25 13:58 pause
-      drwxr-xr-x 2 root root      6 Jan 20 02:01 proc
-      drwxr-xr-x 2 root root      6 Jan 20 02:01 dev
-      drwxr-xr-x 2 root root      6 Jan 20 02:01 sys
-      drwxr-xr-x 2 root root     25 Jan 20 02:01 etc
-      ```
-      which is clearly the pause container indicating that the `busybox` based container image is not exposed to the host.
-
-### Using a Kata pod sandbox for testing with `agent-ctl` or `ctr shim`
-
-Once you have a kata pod sandbox created as described above, either using 
-[`crictl`](#using-crictl-for-end-to-end-provisioning-of-a-kata-confidential-containers-pod-with-an-unencrypted-image), or [Kubernetes](#using-kubernetes-for-end-to-end-provisioning-of-a-kata-confidential-containers-pod-with-an-unencrypted-image)
-, you can use this to test specific components of the Kata confidential
-containers architecture. This can be useful for development and debugging to isolate and test features
-that aren't broadly supported end-to-end. Here are some examples:
-
-- In the first terminal run the pull image on guest command against the Kata agent, via the shim (`containerd-shim-kata-v2`).
-This can be achieved using the [containerd](https://github.com/containerd/containerd) CLI tool, `ctr`, which can be used to
-interact with the shim directly. The command takes the form
-`ctr --namespace k8s.io shim --id <sandbox-id> pull-image <image> <new-container-id>` and can been run directly, or through
-the `ccv0.sh` script to automatically fill in the variables:
-  - Optionally, set up some environment variables to set the image and credentials used:
-    - By default the shim pull image test in `ccv0.sh` will use the `busybox:1.33.1` based test image
-     `quay.io/kata-containers/confidential-containers:signed` which requires no authentication. To use a different
-      image, set the `PULL_IMAGE` environment variable e.g. 
-      ```bash
-      $ export PULL_IMAGE="docker.io/library/busybox:latest"
-      ```
-      Currently the containerd shim pull image
-      code doesn't support using a container registry that requires authentication, so if this is required, see the 
-      below steps to run the pull image command against the agent directly.
-  - Run the pull image agent endpoint with:
-    ```bash
-    $ ~/ccv0.sh shim_pull_image
-    ```
-    which we print the `ctr shim` command for reference
-- Alternatively you can issue the command directly to the `kata-agent` pull image endpoint, which also supports
-  credentials in order to pull from an authenticated registry:
-    - Optionally set up some environment variables to set the image and credentials used:
-        - Set the `PULL_IMAGE` environment variable e.g. `export PULL_IMAGE="docker.io/library/busybox:latest"`
-          if a specific container image is required.
-        - If the container registry for the image requires authentication then this can be set with an environment
-          variable `SOURCE_CREDS`. For example to use Docker Hub (`docker.io`) as an authenticated user first run 
-          `export SOURCE_CREDS="<dockerhub username>:<dockerhub api key>"`
-            > **Note**: the credentials support on the agent request is a tactical solution for the short-term
-              proof of concept to allow more images to be pulled and tested. Once we have support for getting
-              keys into the Kata guest image using the attestation-agent and/or KBS I'd expect container registry
-              credentials to be looked up using that mechanism.
-    - Run the pull image agent endpoint with
-      ```bash
-      $ ~/ccv0.sh agent_pull_image
-      ```
-      and you should see output which includes `Command PullImage (1 of 1) returned (Ok(()), false)` to indicate
-      that the `PullImage` request was successful e.g.
-      ```

-  $ ls -ltr /run/kata-containers/confidential-containers_signed/

-  which should show something like

-  ```
-- Leave the Kata shell by running:
-  ```bash
-  $ exit

-
-## Verifying signed images
-
-For this sample demo, we use local attestation to pass through the required
-configuration to do container image signature verification. Due to this, the ability to verify images is limited
-to a pre-created selection of test images in our test
-repository [`quay.io/kata-containers/confidential-containers`](https://quay.io/repository/kata-containers/confidential-containers?tab=tags).
-For pulling images not in this test repository (called an *unprotected* registry below), we fall back to the behaviour
-of not enforcing signatures. More documentation on how to customise this to match your own containers through local,
-or remote attestation will be available in future.
-
-In our test repository there are three tagged images:
-
-| Test Image | Base Image used | Signature status | GPG key status |
-| --- | --- | --- | --- |
-| `quay.io/kata-containers/confidential-containers:signed` | `busybox:1.33.1` | [signature](https://github.com/kata-containers/tests/tree/CCv0/integration/confidential/fixtures/quay_verification/x86_64/signatures.tar) embedded in kata rootfs |  [public key](https://github.com/kata-containers/tests/tree/CCv0/integration/confidential/fixtures/quay_verification/x86_64/public.gpg) embedded in kata rootfs |
-| `quay.io/kata-containers/confidential-containers:unsigned` | `busybox:1.33.1` | not signed | not signed |
-| `quay.io/kata-containers/confidential-containers:other_signed` | `nginx:1.21.3` | [signature](https://github.com/kata-containers/tests/tree/CCv0/integration/confidential/fixtures/quay_verification/x86_64/signatures.tar) embedded in kata rootfs | GPG key not kept |
-
-Using a standard unsigned `busybox` image that can be pulled from another, *unprotected*, `quay.io` repository we can
-test a few scenarios.
-
-In this sample, with local attestation, we pass in the the public GPG key and signature files, and the [`offline_fs_kbc`
-configuration](https://github.com/confidential-containers/attestation-agent/blob/main/src/kbc_modules/offline_fs_kbc/README.md)
-into the guest image which specifies that any container image from `quay.io/kata-containers`
-must be signed with the embedded GPG key and the agent configuration needs updating to enable this. 
-With this policy set a few tests of image verification can be done to test different scenarios by attempting
-to create containers from these images using `crictl`:
-
-- If you don't already have the Kata Containers CC code built and configured for `crictl`, then follow the 
-[instructions above](#using-crictl-for-end-to-end-provisioning-of-a-kata-confidential-containers-pod-with-an-unencrypted-image)
-up to the `~/ccv0.sh crictl_create_cc_pod` command.
-
-- In order to enable the guest image, you will need to setup the required configuration, policy and signature files
-needed by running 
-`~/ccv0.sh copy_signature_files_to_guest` and then run `~/ccv0.sh crictl_create_cc_pod` which will delete and recreate 
-your pod - adding in the new files.
- 
-- To test the fallback behaviour works using an unsigned image from an *unprotected* registry we can pull the `busybox`
-image by running:
-  ```bash
-  $ export CONTAINER_CONFIG_FILE=container-config_unsigned-unprotected.yaml
-  $ ~/ccv0.sh crictl_create_cc_container
-  ```
-  - This finishes showing the running container e.g.
-  ```text
-  CONTAINER           IMAGE                               CREATED                  STATE               NAME                        ATTEMPT             POD ID
-  98c70fefe997a       quay.io/prometheus/busybox:latest   Less than a second ago   Running             prometheus-busybox-signed   0                   70119e0539238
-  ```
-- To test that an unsigned image from our *protected* test container registry is rejected we can run:
-  ```bash
-  $ export CONTAINER_CONFIG_FILE=container-config_unsigned-protected.yaml
-  $ ~/ccv0.sh crictl_create_cc_container
-  ```
-  - This correctly results in an error message from `crictl`:
-  `PullImage from image service failed" err="rpc error: code = Internal desc = Security validate failed: Validate image failed: The signatures do not satisfied! Reject reason: [Match reference failed.]" image="quay.io/kata-containers/confidential-containers:unsigned"`
-- To test that the signed image our *protected* test container registry is accepted we can run:
-  ```bash
-  $ export CONTAINER_CONFIG_FILE=container-config.yaml
-  $ ~/ccv0.sh crictl_create_cc_container
-  ```
-  - This finishes by showing a new `kata-cc-busybox-signed` running container e.g.
-  ```text
-  CONTAINER           IMAGE                                                    CREATED                  STATE               NAME                        ATTEMPT             POD ID
-  b4d85c2132ed9       quay.io/kata-containers/confidential-containers:signed   Less than a second ago   Running             kata-cc-busybox-signed      0                   70119e0539238
-  ...
-  ```
-- Finally to check the image with a valid signature, but invalid GPG key (the real trusted piece of information we really
-want to protect with the attestation agent in future) fails we can run: 
-  ```bash
-  $ export CONTAINER_CONFIG_FILE=container-config_signed-protected-other.yaml
-  $ ~/ccv0.sh crictl_create_cc_container
-  ```
-  - Again this results in an error message from `crictl`:
-  `"PullImage from image service failed" err="rpc error: code = Internal desc = Security validate failed: Validate image failed: The signatures do not satisfied! Reject reason: [signature verify failed! There is no pubkey can verify the signature!]" image="quay.io/kata-containers/confidential-containers:other_signed"`
-
-### Using Kubernetes to create a Kata confidential containers pod from the encrypted ssh demo sample image
-
-The [ssh-demo](https://github.com/confidential-containers/documentation/tree/main/demos/ssh-demo) explains how to
-demonstrate creating a Kata confidential containers pod from an encrypted image with the runtime created by the
-[confidential-containers operator](https://github.com/confidential-containers/documentation/blob/main/demos/operator-demo).
-To be fully confidential, this should be run on a Trusted Execution Environment, but it can be tested on generic
-hardware as well.
-
-If you wish to build the Kata confidential containers runtime to do this yourself, then you can using the following
-steps:
-
-- Run the full build process with the Kubernetes environment variable set to `"yes"`, so the Kubernetes cluster is
-  configured and created using the VM as a single node cluster and with `AA_KBC` set to `offline_fs_kbc`. 
-  ```bash
-  $ export KUBERNETES="yes"
-  $ export AA_KBC=offline_fs_kbc
-  $ ~/ccv0.sh build_and_install_all
-  ```
-    - The `AA_KBC=offline_fs_kbc` mode will ensure that, when creating the rootfs of the Kata guest, the 
-      [attestation-agent](https://github.com/confidential-containers/attestation-agent) will be added along with the
-      [sample offline KBC](https://github.com/confidential-containers/documentation/blob/main/demos/ssh-demo/aa-offline_fs_kbc-keys.json)
-      and an agent configuration file
-    > **Note**: Depending on how where your VMs are hosted and how IPs are shared you might get an error from docker
-    during matching `ERROR: toomanyrequests: Too Many Requests`. To get past
-    this, login into Docker Hub and pull the images used with:
-  >  ```bash
-  >  $ sudo docker login
-  >  $ sudo docker pull registry:2
-  >  $ sudo docker pull ubuntu:20.04
-  >  ```
-  >  then re-run the command.
-- Check that your Kubernetes cluster has been correctly set-up by running : 
-  ```bash
-  $ kubectl get nodes
-  ```
-  and checking that you see a single node e.g.
-  ```text
-  NAME                             STATUS   ROLES                  AGE   VERSION
-  stevenh-ccv0-k8s1.fyre.ibm.com   Ready    control-plane,master   43s   v1.22.0
-  ```
-- Create a sample Kata confidential containers ssh pod by running:
-  ```bash
-  $ ~/ccv0.sh kubernetes_create_ssh_demo_pod
-  ```
-- As this point you should have a Kubernetes pod running the Kata confidential containers runtime that has pulled
-the [sample image](https://hub.docker.com/r/katadocker/ccv0-ssh) which was encrypted by the key file that we included
-in the rootfs.
-During the pod deployment the image was pulled and then decrypted using the key file, on the Kata guest image, without
-it ever being available to the host.
-
-- To validate that the container is working you, can connect to the image via SSH by running:
-  ```bash
-  $ ~/ccv0.sh connect_to_ssh_demo_pod
-  ```
-  - During this connection the host key fingerprint is shown and should match:
-    `ED25519 key fingerprint is SHA256:wK7uOpqpYQczcgV00fGCh+X97sJL3f6G1Ku4rvlwtR0.`
-  - After you are finished connecting then run:
-    ```bash
-    $ exit
-    ```
-  
-- To delete the sample SSH demo pod run:
-  ```bash
-  $ ~/ccv0.sh kubernetes_delete_ssh_demo_pod
-  ```
-
-## Additional script usage
-
-As well as being able to use the script as above to build all of `kata-containers` from scratch it can be used to just
-re-build bits of it by running the script with different parameters. For example after the first build you will often
-not need to re-install the dependencies, the hypervisor or the Guest kernel, but just test code changes made to the
-runtime and agent. This can be done by running `~/ccv0.sh rebuild_and_install_kata`. (*Note this does a hard checkout*
-*from git, so if your changes are only made locally it is better to do the individual steps e.g.* 
-`~/ccv0.sh build_kata_runtime && ~/ccv0.sh build_and_add_agent_to_rootfs && ~/ccv0.sh build_and_install_rootfs`).
-There are commands for a lot of steps in building, setting up and testing and the full list can be seen by running
-`~/ccv0.sh help`:
-```

-# Kata Containers with AMD SEV-SNP VMs
-
-## Disclaimer
-
-This guide is designed for developers and is - same as the Developer Guide - not intended for production systems or end users. It is advisable to only follow this guide on non-critical development systems.
-
-## Prerequisites
-
-To run  Kata Containers in SNP-VMs, the following software stack is used.
-
-![Kubernetes integration with shimv2](./images/SNP-stack.svg)
-
-The host BIOS and kernel must be capable of supporting AMD SEV-SNP and configured accordingly. For Kata Containers, the host kernel with branch [`sev-snp-iommu-avic_5.19-rc6_v3`](https://github.com/AMDESE/linux/tree/sev-snp-iommu-avic_5.19-rc6_v3) and commit [`3a88547`](https://github.com/AMDESE/linux/commit/3a885471cf89156ea555341f3b737ad2a8d9d3d0) is known to work in conjunction with SEV Firmware version 1.51.3 (0xh\_1.33.03) available on AMD's [SEV developer website](https://developer.amd.com/sev/). See [AMD's guide](https://github.com/AMDESE/AMDSEV/tree/sev-snp-devel) to configure the host accordingly. Verify that you are able to run SEV-SNP encrypted VMs first. The guest components required for Kata Containers are built as described below.
-
-**Tip**: It is easiest to first have Kata Containers running on your system and then modify it to run containers in SNP-VMs. Follow the [Developer guide](../Developer-Guide.md#warning) and then follow the below steps. Nonetheless, you can just follow this guide from the start.
-
-## How to build
-
-Follow all of the below steps to install Kata Containers with SNP-support from scratch. These steps mostly follow the developer guide with modifications to support SNP
-
-__Steps from the Developer Guide:__
-- Get all the [required components](../Developer-Guide.md#requirements-to-build-individual-components) for building the kata-runtime
-- [Build the and install kata-runtime](../Developer-Guide.md#build-and-install-the-kata-containers-runtime)
-- [Build a custom agent](../Developer-Guide.md#build-a-custom-kata-agent---optional)
-- [Create an initrd image](../Developer-Guide.md#create-an-initrd-image---optional) by first building a rootfs, then building the initrd based on the rootfs, use a custom agent and install. `ubuntu` works as the distribution of choice.
-- Get the [required components](../../tools/packaging/kernel/README.md#requirements) to build a custom kernel
-
-__SNP-specific steps:__
-- Build the SNP-specific kernel as shown below (see this [guide](../../tools/packaging/kernel/README.md#build-kata-containers-kernel) for more information)
-```bash
-$ pushd kata-containers/tools/packaging/kernel/
-$ ./build-kernel.sh -a x86_64 -x snp setup
-$ ./build-kernel.sh -a x86_64 -x snp build
-$ sudo -E PATH="${PATH}" ./build-kernel.sh -x snp install
-$ popd
-```
-- Build a current OVMF capable of SEV-SNP:
-```bash
-$ pushd kata-containers/tools/packaging/static-build/ovmf
-$ ./build.sh
-$ tar -xvf edk2-x86_64.tar.gz
-$ popd
-```
-- Build a custom QEMU
-```bash
-$ source kata-containers/tools/packaging/scripts/lib.sh
-$ qemu_url="$(get_from_kata_deps "assets.hypervisor.qemu-snp-experimental.url")"
-$ qemu_tag="$(get_from_kata_deps "assets.hypervisor.qemu-snp-experimental.tag")"
-$ git clone "${qemu_url}"
-$ pushd qemu
-$ git checkout "${qemu_tag}"
-$ ./configure --enable-virtfs --target-list=x86_64-softmmu --enable-debug
-$ make -j "$(nproc)"
-$ popd
-```
-
-### Kata Containers Configuration for SNP
-
-The configuration file located at `/etc/kata-containers/configuration.toml` must be adapted as follows to support SNP-VMs:
-- Use the SNP-specific kernel for the guest VM (change path)
-```toml
-kernel = "/usr/share/kata-containers/vmlinuz-snp.container"
-```
-- Enable the use of an initrd (uncomment)
-```toml
-initrd = "/usr/share/kata-containers/kata-containers-initrd.img"
-```
-- Disable the use of a rootfs (comment out)
-```toml
-# image = "/usr/share/kata-containers/kata-containers.img"
-```
-- Use the custom QEMU capable of SNP (change path)
-```toml
-path = "/path/to/qemu/build/qemu-system-x86_64"
-```
-- Use `virtio-9p` device since `virtio-fs` is unsupported due to bugs / shortcomings in QEMU version [`snp-v3`](https://github.com/AMDESE/qemu/tree/snp-v3) for SEV and SEV-SNP (change value)
-```toml
-shared_fs = "virtio-9p"
-```
-- Disable `virtiofsd` since it is no longer required (comment out)
-```toml
-# virtio_fs_daemon = "/usr/libexec/virtiofsd"
-```
-- Disable NVDIMM (uncomment)
-```toml
-disable_image_nvdimm = true
-```
-- Disable shared memory (uncomment)
-```toml
-file_mem_backend = ""
-```
-- Enable confidential guests (uncomment)
-```toml
-confidential_guest = true
-```
-- Enable SNP-VMs (uncomment)
-```toml
-sev_snp_guest = true
-```
-  - Configure an OVMF (add path)
-```toml
-firmware = "/path/to/kata-containers/tools/packaging/static-build/ovmf/opt/kata/share/ovmf/OVMF.fd"
-```
-
-## Test Kata Containers with Containerd
-
-With Kata Containers configured to support SNP-VMs, we use containerd to test and deploy containers in these VMs.
-
-### Install Containerd
-If not already present, follow [this guide](./containerd-kata.md#install) to install containerd and its related components including `CNI` and the `cri-tools` (skip Kata Containers since we already installed it)
-
-### Containerd Configuration
-
-Follow [this guide](./containerd-kata.md#configuration) to configure containerd to use Kata Containers
-
-## Run Kata Containers in SNP-VMs
-
-Run the below commands to start a container. See [this guide](./containerd-kata.md#run) for more information
-```bash
-$ sudo ctr image pull docker.io/library/busybox:latest
-$ sudo ctr run --cni --runtime io.containerd.run.kata.v2 -t --rm docker.io/library/busybox:latest hello sh
-```
-
-### Check for active SNP:
-
-Inside the running container, run the following commands to check if SNP is active. It should look something like this:
-```
-/ # dmesg | grep -i sev
-[    0.299242] Memory Encryption Features active: AMD SEV SEV-ES SEV-SNP
-[    0.472286] SEV: Using SNP CPUID table, 31 entries present.
-[    0.514574] SEV: SNP guest platform device initialized.
-[    0.885425] sev-guest sev-guest: Initialized SEV guest driver (using vmpck_id 0)
-```
-
-### Obtain an SNP Attestation Report
-
-To obtain an attestation report inside the container, the `/dev/sev-guest` must first be configured. As of now, the VM does not perform this step, however it can be performed inside the container, either in the terminal or in code.
-
-Example for shell:
-```
-/ # SNP_MAJOR=$(cat /sys/devices/virtual/misc/sev-guest/dev | awk -F: '{print $1}')
-/ # SNP_MINOR=$(cat /sys/devices/virtual/misc/sev-guest/dev | awk -F: '{print $2}')
-/ # mknod -m 600 /dev/sev-guest c "${SNP_MAJOR}" "${SNP_MINOR}"
-```
-
-## Known Issues
-
-- Support for cgroups v2 is still [work in progress](https://github.com/kata-containers/kata-containers/issues/927). If issues occur due to cgroups v2 becoming the default in newer systems, one possible solution is to downgrade cgroups to v1:
-```bash
-sudo sed -i 's/^\(GRUB_CMDLINE_LINUX=".*\)"/\1 systemd.unified_cgroup_hierarchy=0"/' /etc/default/grub
-sudo update-grub
-sudo reboot
-```
-- If both SEV and SEV-SNP are supported by the host, Kata Containers uses SEV-SNP by default. You can verify what features are enabled by checking `/sys/module/kvm_amd/parameters/sev` and `sev_snp`. This means that Kata Containers can not run both SEV-SNP-VMs and SEV-VMs at the same time. If SEV is to be used by Kata Containers instead, reload the `kvm_amd` kernel module without SNP-support, this will disable SNP-support for the entire platform.
-```bash
-sudo rmmod kvm_amd && sudo modprobe kvm_amd sev_snp=0
-```

 3. Certain features will not work when rootless VMM is enabled, including:
    1. Passing devices to the guest (`virtio-blk`, `virtio-scsi`) will not work if the non-privileged user does not have permission to access it (leading to a permission denied error). A more permissive permission (e.g. 666) may overcome this issue. However, you need to be aware of the potential security implications of reducing the security on such devices.
    2. `vfio` device will also not work because of permission denied error.

-# Configure Kata Containers to use EROFS build rootfs
-
-## Introduction
-For kata containers, rootfs is used in the read-only way. EROFS can noticeably decrease metadata overhead.
-
-`mkfs.erofs` can generate compressed and uncompressed EROFS images.
-
-For uncompressed images, no files are compressed. However, it is optional to inline the data blocks at the end of the file with the metadata.
-
-For compressed images, each file will be compressed using the lz4 or lz4hc algorithm, and it will be confirmed whether it can save space. Use No compression of the file if compression does not save space.
-
-## Performance comparison
-|                 | EROFS | EXT4 | XFS |
-|-----------------|-------| --- | --- |
-| Image Size [MB] | 106(uncompressed) | 256 | 126 |
-
-
-## Guidance
-### Install the `erofs-utils`
-#### `apt/dnf` install
-On newer `Ubuntu/Debian` systems, it can be installed directly using the `apt` command, and on `Fedora` it can be installed directly using the `dnf` command.
-
-```shell
-# Debian/Ubuntu
-$ apt install erofs-utils
-# Fedora
-$ dnf install erofs-utils
-```
-
-#### Source install
-[https://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs-utils.git](https://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs-utils.git)
-
-##### Compile dependencies
-If you need to enable the `Lz4` compression feature, `Lz4 1.8.0+` is required, and `Lz4 1.9.3+` is strongly recommended.
-
-##### Compilation process
-For some old lz4 versions (lz4-1.8.0~1.8.3), if lz4-static is not installed, the lz4hc algorithm will not be supported. lz4-static can be installed with apt install lz4-static.x86_64. However, these versions have some bugs in compression, and it is not recommended to use these versions directly.
-If you use `lz4 1.9.0+`, you can directly use the following command to compile.
-
-```shell
-$ ./autogen.sh
-$ ./configure
-$ make
-```
-
-The compiled `mkfs.erofs` program will be saved in the `mkfs` directory. Afterwards, the generated tools can be installed to a system directory using make install (requires root privileges).
-
-### Create a local rootfs
-```shell
-$ export distro="ubuntu"
-$ export FS_TYPE="erofs"
-$ export ROOTFS_DIR="realpath kata-containers/tools/osbuilder/rootfs-builder/rootfs"
-$ sudo rm -rf "${ROOTFS_DIR}"
-$ pushd kata-containers/tools/osbuilder/rootfs-builder

-
-### Add a custom agent to the image - OPTIONAL
-> Note:
-> - You should only do this step if you are testing with the latest version of the agent.
-```shell
-$ sudo install -o root -g root -m 0550 -t "${ROOTFS_DIR}/usr/bin" "${ROOTFS_DIR}/../../../../src/agent/target/x86_64-unknown-linux-musl/release/kata-agent"

-```
-
-### Build a root image
-```shell
-$ pushd  kata-containers/tools/osbuilder/image-builder
-$ script -fec 'sudo -E ./image_builder.sh "${ROOTFS_DIR}"'
-$ popd
-```
-
-### Install the rootfs image
-```shell
