This is a re-vendor of intel/govmm, with support for hot-plugging IBM
Adjunct Processor (AP) devices over VFIO. This is necessary for
enabling AP device pass-through in Kata (see #491).

When a one-shot pod dies in CRI-O, the shimv2 process isn't killed until
the pod is actually deleted, even though the VM is shut down. In this
case, the shim appears to busyloop when attempting to talk to the (now
dead) agent via VSOCK. To address this, we disconnect from the agent
after the VM is shut down.
This is especially catastrophic for one-shot pods that may persist for
hours or days, but it also applies to any shimv2 pod where Kata is
configured to use VSOCK for communication.
See github.com/kata-containers/runtime#2719 for details.

The logic for the debug console meant that if the debug console was

Print a simple version string rather than delaying the output
to display a structured version string. The structured output
is potentially more useful but:
- This output is not consistent with other components.
- Delaying the output makes `--version` unusable in some
environments (since a lot of setup is called before the
version string can be output).

Highlights for cloud-hypervisor version 0.9.0 include:
virtiofs updates to new dax implementation based in qemu 5.0
Fixed random issues caused due to seccomp filters
io_uring Based Block Device Support
If the io_uring feature is enabled and the host kernel supports it then io_uring will be used for block devices. This results a very significant performance improvement.
Block and Network Device Statistics
Statistics for activity of the virtio network and block devices is now exposed through a new vm.counters HTTP API entry point. These take the form of simple counters which can be used to observe the activity of the VM.
HTTP API Responses
The HTTP API for adding devices now responds with the name that was assigned to the device as well the PCI BDF.
CPU Topology
A topology parameter has been added to --cpus which allows the configuration of the guest CPU topology allowing the user to specify the numbers of sockets, packages per socket, cores per package and threads per core.
Release Build Optimization
Our release build is now built with LTO (Link Time Optimization) which results in a ~20% reduction in the binary size.
Hypervisor Abstraction
A new abstraction has been introduced, in the form of a hypervisor crate so as to enable the support of additional hypervisors beyond KVM.
Snapshot/Restore Improvements
Multiple improvements have been made to the VM snapshot/restore support that was added in the last release. This includes persisting more vCPU state and in particular preserving the guest paravirtualized clock in order to avoid vCPU hangs inside the guest when running with multiple vCPUs.
Virtio Memory Ballooning Support
A virtio-balloon device has been added, controlled through the resize control, which allows the reclamation of host memory by resizing a memory balloon inside the guest.
Enhancements to ARM64 Support
The ARM64 support introduced in the last release has been further enhanced with support for using PCI for exposing devices into the guest as well as multiple bug fixes. It also now supports using an initramfs when booting.
Intel SGX Support
The guest can now use Intel SGX if the host supports it. Details can be found in the dedicated SGX documentation.
Seccomp Sandbox Improvements
The most frequently used virtio devices are now isolated with their own seccomp filters. It is also now possible to pass --seccomp=log which result in the logging of requests that would have otherwise been denied to further aid development.
Notable Bug Fixes
Our virtio-vsock implementation has been resynced with the implementation from Firecracker and includes multiple bug fixes.
CPU hotplug has been fixed so that it is now possible to add, remove, and re-add vCPUs (#1338)
A workaround is now in place for when KVM reports MSRs available MSRs that are in fact unreadable preventing snapshot/restore from working correctly (#1543).
virtio-mmio based devices are now more widely tested (#275).
Multiple issues have been fixed with virtio device configuration (#1217)
Console input was wrongly consumed by both virtio-console and the serial. (#1521)

Along with the release of cloud-hypervisor v0.8.0, this option has been
deprecated. clh now enforces to use the alternative controls,
e.g. "shared" and "hugepages", which can infer the backing file
paths. Also, we don't use "hugepages" in kata, so we are fine now as the
"shared" control is already enabled.
