4606f0f28a tests: Make migration test case X86 only
Set the test case test_snapshot_restore X86 only, instead of excluding
it from test command line.

The command line option was added because we used to support migration
with Virtio-MMIO, but not Virtio-PCI.

8c268e351c tests: Port more tests to use wait_vm_boot
Tests not ported include 1) the ones that start guest VMs without
network (e.g. test_net_hotplug, test_initramfs), 2) test_vfio that
involves l2 guest. Also, some tests that use bionic guest image are
given extended timeout (120s) for 'wait_vm_boot'.

26783fea89 tests: Wait explicitly for vm shutdown w/ the 'wait-timeout' crate
Instead of waiting blindly with fixed amount of sleeping time, we can
use the `wait-timeout` crate to explicitly wait VM shutdown (with a
timeout). It can reduces the execution time of some tests
substantially. Also, this patch increases the `shutdown` timeout for
'test_reboot', which should fix the recent sporadic failures on this
test.

8c92d1dbdc tests: Wait explicitly for the guest vm to boot
Instead of blindly waiting for 20-40s for the guest VM to boot, this
patch waits the notification from the guest VM explicitly by using a
simple TcpListener on the host and a custom systemd service in the
guest.

This patch also ported few tests to use this new machanism, while more
tests are to be ported.

d598341534 tests: Add Windows guest integration test
This is a new integration test running Windows as a guest with Cloud
Hypervisor. Once the VM is booted, the test connects to the guest
through SSH and shutdown the VM. If this succeeds, this means the VM
was properly booted to userspace and that the network was functional.

Important to note that because this test generates lots of logs, it
requires a large pipe size for both stdout and stderr.

67025948dc ci: Simplify test scripts
Since all unit and integration tests are run inside containers because

to apply specific capabilities and run cargo tests in a dedicated 'kvm'
group.

2441798fe4 tests: Resize the pipe size to 256K for capturing child stdout/err
As discussed in #1707, the `vcpu` thread can be stalled when using
`--serial tty`. To workaround that issue, this patch enforces to resize
the pipe size to 256K when we capture the stdout/stderr of the
cloud-hypervisor child process in the integration tests. Note that the
pipe size (256K) is chosen based on the output size of our integration
tests at this point, which may need to be increased in the future.

e15dba2925 vmm: Rename NUMA option 'id' into 'guest_numa_id'
The goal of this commit is to rename the existing NUMA option 'id' with
'guest_numa_id'. This is done without any modification to the way this
option behaves.

The reason for the rename is caused by the observation that all other
parameters with an option called 'id' expect a string to be provided.

Because in this particular case we expect a u32 representing a proximity
domain from the ACPI specification, it's better to name it with a more
explicit name.

33c5d6bb98 tests: Enable test_aarch64_pe_boot case for AArch64
The compiled AArch64 linux kernel by running `make` is in PE format
instead of vmlinux, vmlinux.pvh and bzImage format. Therefore we
need to add integration test for this case.

bb9174601a ci: Separate parallel vs sequential tests
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.

c2920d2b6b ci: Move from Clear Linux to Ubuntu Focal Fossa cloud image
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.

135ee4568e tests: Enhance rate_limited_copy() to also consider free disk space
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.

4b64f2a027 vmm: cpu: Reuse already allocated vCPUs if available
When a request is made to increase the number of vCPUs in the VM attempt
to reuse any previously removed (and hence inactive) vCPUs before
creating new ones.

This ensures that the APIC ID is not reused for a different KVM vCPU
(which is not allowed) and that the APIC IDs are also sequential.

The two key changes to support this are:

* Clearing the "kill" bit on the old vCPU state so that it does not
  immediately exit upon thread recreation.
* Using the length of the vcpus vector (the number of allocated vcpus)
  rather than the number of active vCPUs (.present_vcpus()) to determine
  how many should be created.

This change also introduced some new info!() debugging on the vCPU
creation/removal path to aid further development in the future.

TEST=Expanded test_cpu_hotplug test.

9f2eddd9d8 ci: Fix test_serial_off
The integration test validating that --serial off works correctly was
not properly written as it was using the FW, which by default would use
the kernel command line found in the EFI partition. Unfortunately, this
kernel command line was including "console=ttyS0", which causes the
kernel to try to write to the serial port, even if there's no serial
port being emulated.

The problem is, when no emulation of the serial port is provided, the
default value returned on 0x3f8 is 0, which makes the guest kernel think
that some data needs to be read.

The only way to avoid all this is by ensuring we can control the kernel
command line by removing any occurence of "console=ttyS0" from it.

ba4ec7fce2 ci: Extend snapshot_restore_test with hotplug
There's a simple way to trigger PCI BAR reprogramming for a given
device, by removing it and then hotplugging it back. The Linux kernel
will simply choose to place the BARs at different location than the ones
chosen by Cloud-Hypervisor. By doing so, and creating the snapshot after
this hotplug operation, we can manage to validate that the resource are
correctly restored for a given virtio-pci device.
