31dfe3d02a tests: Enable live upgrade tests
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.

Fixes: #3949

8f3462b3e3 tests: live_migration: Run most tests in parallel
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.

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.

7a3d8c6299 tests: Construct firmware path from tests explicitly
Instead of using hardcoded firmware paths inside the `Guest` struct
constructor, this commit removes `fw_path` related code paths from the
`Guest` struct and asks each test constructs its firmware path
explicitly. This allows better flexibility for the `Guest` struct so
that it can be reused for the performance tests we are adding soon.

Now that multiple file descriptors can be provided along with add-net,
that means we can hotplug a multiqueue macvtap interface to the VM.

The common macvtap test is updated, meaning that both coldplug and
hotplug codepath now use multiqueue.

00bb1ea1d5 tests: Enhance test for multiple PCI segments
This commit enhances the integration test for multiple PCI segments
by:

(1) Enables the `test_virtio_fs_multi_segment` on AArch64.

(2) Adds a new integration test case for both x86_64 and AArch64 using
the direct kernel boot to test virtio-disk multiple PCI segments.
The test case does:
- Start a VM using direct kernel boot with 16 PCI segments and assign
the last PCI segment with a virtio-disk device.
- Check if the number of PCI host bridges equals to 16 after VM boots.
- Mount the virtio-disk device on the last PCI segment to the rootfs
and write/read data to the virtio-disk device.

9dc9e224b9 tests: Enable IOMMU test case on AArch64
For AArch64, now virtual IOMMU is only tested on FDT, not ACPI.
In the case of FDT, the behavior of IOMMU is a bit different with ACPI.
All the devices on the PCI bus will be attached to the virtual IOMMU,
except the virtio-iommu device itself. So these devices will all be
added to IOMMU groups, and appear in folder '/sys/kernel/iommu_groups/'.

The result is, on AArch64 IOMMU group '0' contains "0000:00:01.0" which
is the console device. But on X86, console device is not attached to
IOMMU. So the IOMMU group '0' contains "0000:00:02.0" which is the first
disk.

48d1a31e08 tests: Introduce test_macvtap_hotplug
The existing test_macvtap is factorized to be able to support both
coldplug and hotplug of a macvtap interface through virtio-net. Adding
the new test_macvtap_hotplug test allows for validating that sending a
TAP file descriptor through control message along with the add-net
command works.

28b80ba42a tests: Change string checking for console success
The output from getty ("login:") does not always appear. This can be
observed interactively when booting the VM. (Mashing return will bring
it up.) Instead of checking for that string to ensure the VM has booted
instead check for a message from systemd to say it has started the SSH
daemon.

d330d91e1a tests: Optimize integration test on AArch64
AArch64 tests were divided into 2 steps:
- Build and test with 'acpi' feature
- Build and test without 'acpi'

This can be optimized. We need only to build and test once with default
features ('acpi' is enabled).

On AArch64, ACPI only works with UEFI. If UEFI is not available, guest
kernel fall back to use FDT. Most AArch64 test cases boot from direct
kernel, the guest will keep using FDT even if ACPI is enabled. So
nothing is broken.

4d36ecef9e tests: Fix virtio_balloon integration test
The virtio_balloon test is a bit flaky since we can't really know how
much the balloon is gonna be deflated when the guest is under memory
pressure. That's why it's safer to simply check that the balloon is not
the initial size anymore.

One small detail, but we don't need to check for the balloon size to be
higher than 0 since the returned value is a u64.

2c576ab312 test: Introduce test_virtio_balloon() function
The new test_virtio_balloon() is to verify if the 'deflate_on_oom'
parameter works. Its testing result is as follows:

1. Start a 4G guest with 2G balloon, check memory once starts up.
total_mem    is 4294967296 bytes
actual_mem   is 2147483648 bytes
orig_balloon is 2147483648 bytes
       total      used      free    shared    buff/cache    available
Mem:   3.8Gi     2.1Gi     1.6Gi     0.0Ki         140Mi        1.6Gi
Swap:     0B        0B        0B

2. Run a command in guest to eat up 25G memory, and check again.
total_mem        is 4294967296 bytes
actual_mem       is 3121610752 bytes
deflated_balloon is 1173356544 bytes
       total      used      free    shared    buff/cache    available
Mem:   3.8Gi     1.2Gi     2.6Gi     0.0Ki          49Mi        2.5Gi
Swap:     0B        0B        0B

From above, we can notice the balloon memory indeed deflates from
2147483648 bytes to 1173356544 bytes once an oom is going to be
triggered.

57f70c0761 tests: Simplify Windows guest boot and DHCP setup
A new method has been introduced for WindowsGuest, that would poll on
the SSH connection and try to execute a test command. When successfull,
the polling stops and the guest is considered finished boot. The
downside of this method is that the network setup is needed always even
if the test doesn't use network, however it complies with the behavior
of other tests. I also observe a bit more stability on the local test
run, however it still appears to be a resource issue so some sporadic
fails are possible on a slower machine.

The hardcoded timeouts for guest boot and DHCP setup have been removed.

The dnsmasq invocation uses `--bind-dynamic` so then the daemon can be
started while the target interface could be down yet.
