This patch upgrades Firecracker version from v1.1.0 to v1.4.0.
* Generate swagger models for v1.4.0 (from `firecracker.yaml`)
- The version of go-swagger used is v0.30.0
* The firecracker v1.4.0 includes the following changes.
- Added
* Added support for custom CPU templates allowing users to adjust vCPU features
exposed to the guest via CPUID, MSRs and ARM registers.
* Introduced V1N1 static CPU template for ARM to represent Neoverse V1 CPU
as Neoverse N1.
* Added support for the virtio-rng entropy device. The device is optional. A
single device can be enabled per VM using the /entropy endpoint.
* Added a cpu-template-helper tool for assisting with creating and managing
custom CPU templates.
- Changed
* Set FDP_EXCPTN_ONLY bit (CPUID.7h.0:EBX[6]) and ZERO_FCS_FDS bit
(CPUID.7h.0:EBX[13]) in Intel's CPUID normalization process.
- Fixed
* Fixed feature flags in T2S CPU template on Intel Ice Lake.
* Fixed CPUID leaf 0xb to be exposed to guests running on AMD host.
* Fixed a performance regression in the jailer logic for closing open file
descriptors.
* A race condition that has been identified between the API thread and the VMM
thread due to a misconfiguration of the api_event_fd.
* Fixed CPUID leaf 0x1 to disable perfmon and debug feature on x86 host.
* Fixed passing through cache information from host in CPUID leaf 0x80000006.
* Fixed the T2S CPU template to set the RRSBA bit of the IA32_ARCH_CAPABILITIES
MSR to 1 in accordance with an Intel microcode update.
* Fixed the T2CL CPU template to pass through the RSBA and RRSBA bits of the
IA32_ARCH_CAPABILITIES MSR from the host in accordance with an Intel microcode
update.
* Fixed passing through cache information from host in CPUID leaf 0x80000005.
* Fixed the T2A CPU template to disable SVM (nested virtualization).
* Fixed the T2A CPU template to set EferLmsleUnsupported bit
(CPUID.80000008h:EBX[20]), which indicates that EFER[LMSLE] is not supported.
Fixes: #7610

Kata Containers
Welcome to Kata Containers!
This repository is the home of the Kata Containers code for the 2.0 and newer releases.
If you want to learn about Kata Containers, visit the main Kata Containers website.
Introduction
Kata Containers is an open source project and community working to build a standard implementation of lightweight Virtual Machines (VMs) that feel and perform like containers, but provide the workload isolation and security advantages of VMs.
License
The code is licensed under the Apache 2.0 license. See the license file for further details.
Platform support
Kata Containers currently runs on 64-bit systems supporting the following technologies:
| Architecture | Virtualization technology |
|---|---|
x86_64, amd64 |
Intel VT-x, AMD SVM |
aarch64 ("arm64") |
ARM Hyp |
ppc64le |
IBM Power |
s390x |
IBM Z & LinuxONE SIE |
Hardware requirements
The Kata Containers runtime provides a command to determine if your host system is capable of running and creating a Kata Container:
$ kata-runtime check
Notes:
This command runs a number of checks including connecting to the network to determine if a newer release of Kata Containers is available on GitHub. If you do not wish this to check to run, add the
--no-network-checksoption.By default, only a brief success / failure message is printed. If more details are needed, the
--verboseflag can be used to display the list of all the checks performed.If the command is run as the
rootuser additional checks are run (including checking if another incompatible hypervisor is running). When running asroot, network checks are automatically disabled.
Getting started
See the installation documentation.
Documentation
See the official documentation including:
Configuration
Kata Containers uses a single configuration file which contains a number of sections for various parts of the Kata Containers system including the runtime, the agent and the hypervisor.
Hypervisors
See the hypervisors document and the Hypervisor specific configuration details.
Community
