ad223f2b50 fs: Use cache=none by default
The cache= option from the virtiofsd backend is meant to be used
depending on how the user wants to use the guest page cache. For most
use cases, we want to bypass the guest page cache to reduce the guest
memory footprint, which is why "cache=none" should be the default.

"cache=always" is the other option when the user wants to do something
specific by using the guest page cache, but should not be the default
anymore.

43d2e09e1f ci: Add unit tests to compare CLI and OpenAPI
The goal here is to ensure that CLI and OpenAPI both behave as closely

Leveraging the reorganization of the code, we can now compare two
VmConfig structures generated from one CLI entry on one side, and from
an OpenAPI entry (JSON payload) on the other side.

63c30a6e79 vmm: Build and set the list of external mappings for VFIO
When VFIO devices are created and if the device is attached to the
virtual IOMMU, the ExternalDmaMapping trait implementation is created
and associated with the device. The idea is to build a hash map of
device IDs with their associated trait implementation.

This hash map is provided to the virtual IOMMU device so that it knows
how to properly trigger external mappings associated with VFIO devices.

80c3fd922a ci: Allow enough time for L2 VM to boot
Because the L2 VM running in the VFIO integration test is actually
running as L3 (since the CI runs in a VM), it can take quite some
time for this VM to boot.

The way to solve this issue is to extend the sleep time before to try
communicating with the L2 VM, but also to speed up the boot time by
using virtio-console instead of serial. We suspect the use of serial,
implying PIO VM exits for each character on the serial port is quite
expensive compared to the paravirtualized console.

2f1ff23066 vmm: (Re-)Introduce a VMM structure
Unlike the Vmm structure we removed with commit bdfd1a3f, this new one

For that, we implement a control loop that will replace the one that's
currently embedded within the Vm structure itself.
This will allow us to decouple the VM lifecycle management from the VM
object itself, by having a constantly running VMM control loop.

Besides the VM specific events (exit, reset, stdin for now), the VMM
control loop also handles all the Cloud Hypervisor IPC requests.

5f0337c21d tests: Add a "huge" memory test
Now that we have expanded our address space we should add automated
testing to try VMs that use a large amount of RAM.

As the hypervisor does an anonymous mmap() for the backing of memory and
during a typical test boot the guest will not touch it all it should be
possible to test large RAM VMs even if that exceeds the RAM of the host
machine.

69e27288a2 vmm: Allocate enough MSI-X vectors for multiqueue virtio devices
The default number of MSI-X vector allocated was 2, which is the minimum
defined by the virtio specification. The reason for this minimum is that
virtio needs at least one interrupt to signal that configuration changed
and at least one to specify something happened regarding the virtqueues.

But this current implementation is not optimal because our VMM supports
as many MSI-X vectors as allowed by the MSI-X specification (2048 max).
For that reason, the current patch relies on the number of virtqueues
needed by the virtio device to determine the right amount of MSI-X
vectors needed. It's important not to forget the dedicated vector for
any configuration change too.

dc31db478a ci: Fix virtio-fs tests
The virtiofsd daemon takes a bit of time creating and listening on the
socket. By adding 10s timeout, we make sure the vhost-user socket has
been properly created before the VMM tries to connect to it.

Also, the daemon needs cap_dac_override capabilities to access debugfs
filesystem.

Last thing, both virtio-fs and virtio-pmem tests were slightly different
from the others since they were not explicitly killing cloud-hypervisor
and virtiofsd processes once the test was done.

In order to support the more performant version of virtio-fs, that is
the one relying on a shared memory region between host and guest, we
introduce two new parameters to the --fs device.

The "dax" parameter allows the user to choose if he wants to use the
shared memory region with virtio-fs. By default, this parameter is "on".

The "cache_size" parameter allows the user to specify the amount of
memory that should be shared between host and guest. By default, the
value of this parameter is 8Gib as advised by virtio-fs maintainers.

Note that dax=off and cache_size are incompatible.
