and the test is carried out using the GNU toolchain.

The compiled AArch64 linux kernel by running `make` is in PE format
instead of vmlinux, vmlinux.pvh and bzImage format. Therefore we
need to add integration test for this case.

This commit adds supporting components and code for enabling the
AArch64 integration tests, including:
1. A Linux kernel config file to build kernel on AArch64 machines.
2. Refactoring the `run_integration_test.sh` to architecture
specific scripts for readability.

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy
dependency that these vhost-user backends had.

Refactored the construction of KVM IOCTL rules for Seccomp.
Separating the rules by architecture can reduce the risk of bugs and

In order to move the hypervisor specific parts of the VM exit handling
path, we're defining a generic, hypervisor agnostic VM exit enum.
This is what the hypervisor's Vcpu run() call should return when the VM
exit can not be completely handled through the hypervisor specific bits.
For KVM based hypervisors, this means directly forwarding the IO related
exits back to the VMM itself. For other hypervisors that e.g. rely on the
VMM to decode and emulate instructions, this means the decoding itself
would happen in the hypervisor crate exclusively, and the rest of the VM
exit handling would be handled through the VMM device model implementation.

Now that our CI has transitioned from ClearLinux to Ubuntu images
exclusively, let's update the documentation to refer to Ubuntu images
instead of ClearLinux's ones.

Now that the project relies on Ubuntu images, the documentation related

In order to differentiate tests that can be run in parallel versus
tests that must be run on their own, we move all tests into dedicated
modules.
The point is to avoid glitches in results that can be caused by the fact
that other tests (hence VMs) are running at the same time.

Move the CI to rely entirely on Ubuntu cloud images. It's worth noting
that both QCOW2 and RAW images from Ubuntu Focal Fossa have been
modified to include the tools needed from integration tests.
This means fio, iperf, iperf3, netcat and socat have been added to the
image. The snapd package have been fully removed as it was expecting the
support for squashfs (not present when using our own kernel from direct
kernel boot), which was causing some failures, and was preventing
cloud-init from terminating properly.

With QCOW disk images the space needed is greater than the size of the
iamge as any "zero" blocks in the image are allocated when they are
touched making the image bigger.
Here we add a threshold of 6GiB with added debugging messages to ensure

This update of Dockerfile will add support to the AArch64
integration tests and musl building, including:
1. Installation of the missing `setcap` binary on AArch64.
On AArch64, `setcap` binary should be installed via `libcap2-bin`.
This binary is needed in the integration test.
2. Related support for the cloud-hypervisor binary building by
musl toolchain.

On x86 architecture, we need to save a list of MSRs as part of the vCPU

Some vCPU states such as MP_STATE can be modified while retrieving
other states. For this reason, it's important to follow a specific
order that will ensure a state won't be modified after it has been
saved. Comments about ordering requirements have been copied over
from Firecracker commit 57f4c7ca14a31c5536f188cacb669d2cad32b9ca.
This patch also set the previously saved VCPU_EVENTS, as this was
missing from the restore codepath.
