With vhost_user_fs binary moved to its own crate the dependencies in the
top level can be trimmed significantly.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
The binary is still built in the same location but the source code and
the dependencies for it come from the vhost_user_fs crate itself.
The binary will be built with:
`cargo build --all --bin vhost_user_fs` or just `cargo build --all`

The _fd suffix is KVM specific. But since it now point to an hypervisor
agnostic hypervisor::Vm implementation, we should just rename it vm.

The fd naming is quite KVM specific. Since we're now using the
hypervisor crate abstractions, we can rename those into something more
readable and meaningful.

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
to the creation of a custom image has been updated. It's important to
note this procedure could be applied to any other distribution, given
that the package manager's commands would be slightly different.

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.

Split the generic virtio code (queues and device type) from the
VirtioDevice trait, transport and device implementations.
This also simplifies the feature handling in vhost_user_backend as the
vm-virtio crate is no longer has any features.

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.

Updating the cloud-init files related to Ubuntu images is needed to be
able to use Ubuntu images for running all integration tests.

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
that there is sufficient disk space to run the tests.

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.

Extend the existing integration test test_snapshot_restore by testing
with more than one vCPU.

On x86 architecture, we need to save a list of MSRs as part of the vCPU
state. By providing the full list of MSRs supported by KVM, this patch
fixes the remaining snapshot/restore issues, as the vCPU is restored
with all its previous states.

Add a new function to the hypervisor trait so that the caller can
retrieve the list of MSRs supported by this hypervisor.

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.

The logic can be shared among hypervisor implementations.
The 'static bound is used such that we don't need to deal with extra
lifetime parameter everywhere. It should be okay because we know the
entry type E doesn't contain any reference.

This trait contains a function which produces a interrupt routing entry.
Implement that trait for KvmRoutingEntry and rewrite the update
function.

The observation is only the route entry is hypervisor dependent.
Keep a definition of KvmMsiInterruptManager to avoid too much code
churn.

This is basic and incomplete support but Linux correctly finds the DMI
