1a2185ea96 tests: Modernise SGX testing
The jammy disk image has a new enough kernel to support SGX and if we
rely on just the CPUid information (which is sufficient) then we can use
the regular jammy test image for testing.

d3a8332282 tests: Remove test_reboot
There is no need for this test any longer as we have plenty of other
tests that reboot the VM.

Further this test used unmodified bionic image, which not only will be
EOLed soon but also took a long time to shutdown as it still had snapd
installed.

958ef69295 tests: Rely on wtmp (the login records) to count reboot times
The systemd journal has a known issue of generating large size logs[1],
which makes it unreliable as a source for retrieving system
information, such as for counting reboot times. This is particularly
problematic on disk-constrained systems, like the VMs we launched for
our integration tests, where the disk size is normally 2GB. By default,
the systemd journal has a size limit of 10% of the size of the
underlying file system (e.g. around 200MB for the VMs of our integration
tests), which would remove archived journal files on demand.

A better alternative to count reboot times is based on information from
`wtmp` (e.g. the login records) which is much more concise and can be
accessed via the `last` command.

76dbf85b79 net: Give the user the ability to set MTU
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.

944d09208e ci: Initial Windows image integration
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.

6d452fad52 tests: Improve test_virtio_block_topology reliability
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.

dc75519372 tests: Improve reliability of test_bionic_ovmf
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.

103494f441 tests: Improve live migration tests reliability
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).

fa0565234c tests: Make test_api_shutdown and test_api_delete more reliable
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.
