Add a new "mtu" parameter to the NetConfig structure and therefore to
the --net option. This allows Cloud Hypervisor's users to define the
Maximum Transmission Unit (MTU) they want to use for the network
interface that they create.
In details, there are two main aspects. On the one hand, the TAP
interface is created with the proper MTU if it is provided. And on the
other hand the guest is made aware of the MTU through the VIRTIO
configuration. That means the MTU is properly set on both the TAP on the
host and the network interface in the guest.

This function starts the 'receive-migration' for the destination VM,
'send-migration' for the source VM, waits for the live-migration
completion, and prints debug information upon errors.

This patch moves the actual test logic and assertions from various
functions to the actual tests, which makes these tests more readable and

Following our recent v26.0 release we can re-enable our live upgrade
tests to try and make it possible for us to move to making LTS releases.
Currently limited to x86-64 as the live upgrade tests fail on aarch64.

Only the ovs-dpdk live-migration tests need to run sequentially as they
use the same ovs-dpdk setup.
This is to reduce our CI time, particularly for the live-migration
and aarch64 jobs.

This enables the Windows test module. One basic test is enabled,
while all others are disabled yet for aarch64. Jenkins file is
extended with the corresponding step for aarch64.
installAzureCli() is parametrized.
It seems that transferring a 30GB image would take >= 15 minutes. An
optimization here is having a gzip'ed image to 10GB which would unpack
in 3 minutes. Expect to be quicker than transferring an uncompressed
image while on another network.

The test test_virtio_block_topology has been recently failing due to an
error happening in losetup while trying to set the block size. Since
there's no option in losetup for retrying, we took the approach of
programming the expected behavior of creating a loop device relying
directly on the system ioctl LOOP_CONFIGURE. We apply a retry loop based
on the result returned by this ioctl, so that we don't fail on the first
try. We also added a sleep before retrying, hoping this would help the
next iteration to succeed.

It's been observed on the Bionic image that udev and snapd services can
cause some delay in the VM's shutdown. Disabling them before shutting
down the VM improves the reliability of the test.
Also increasing slightly the sleep time to ensure we give the VM enough
time to shutdown before checking the list of events provided by the
event monitor.

Since it's not possible to run the integration test test_vfio on Azure
at the moment (because of some nested virtualization issues), we can
temporarily run it on the baremetal CI where we already run some VFIO
tests.

Move the live migration tests to a 'jammy' worker rather than
'jammy-small'. This type of worker has more CPUs (64 vs 16) and more RAM
(256G vs 64G), which should improve the time it takes to run each test.
With this improvement, the test shouldn't fail anymore due to timeout
being reached.
A second improvement is to reduce the amount of vCPUs created for each
VM. The point is simply to check we can migrate a VM with multiple
vCPUs, therefore using 2 instead of 6 should be enough when possible.
When testing NUMA, we can't lower the amount of vCPUs since there's a
quite complex topology that is expected there.
Also, the total amount of vCPUs is reduced from 12 to 4 (again when not
testing with NUMA).

Both of these tests have been sporadically failing through multiple CI
runs. The reason is related to cloud-init which fails to run the
"init-local" script during the second boot of the VM. This causes the
network interface to not be available, and therefore the test can't SSH
into the VM as expected. The root cause is the filesystem and cache
corruption that happens on the cloud-init disk.
The way to prevent from this issue is to sync the guest filesystem
before we shut it down, and as a security harness, we also wait for a
few seconds for the shutdown command to complete inside the guest before
we trigger the API shutdown or delete.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
It might sometimes take a few seconds for the guest to trigger the OOM
and report it back to the host. That's why this patch adds some sleep
time between the command in the guest supposedly triggering the OOM and
the check of the balloon size from the host.
