It is permissable for the driver to program fewer queues than offered by
the device. Filter the queues so that only the ready ones are included
and check that they have valid addresses configured.

Don't assume that the number of queues provided match the number of
queues offered. The virtio spec allows the driver to program fewer
queues.

We should use full memory barrier to ensure both guest and us
can see the correct avail_idx and avail_event_idx. Something
like this pattern:
VM: CLH:
update vring.avail->idx update avail_event_idx
mb() mb()
read avail_event_idx read vring.avail->idx

Rather than having to give and return the ioeventfd used for a device
clone them each time. This will make it simpler when we start handling
the driver enabling fewer queues than advertised by the device.

In order to make the thread naming more useful derive their name from
the device id (which can be supplied by the user) and a device specific
suffix that has details of the individual queue (or queue pair.)

The Windows image is quite large (about 20GiB), hence it takes some time
to copy it for every test in order to avoid potential corruption.
One way to mitigate that without compromising on safety between each
test is by using device mapper. By creating a read-only base, we ensure
the image won't be modified by any of the tests, and by creating one
snapshot for each test, we avoid copying the entire image each time.
A dedicated Copy On Write disk image is created to handle any change
that might be performed on the base image, letting the tests behave as
expected.

By relying on the Guest object, Windows dedicated tests copy the Windows
guest image before booting from it. The point being to avoid corruption
between multiple tests. This is already how the rest of the integration
tests work, Windows tests were the only ones missing this feature.

This image does not have the pollinate service which can sometimes fail
and prevent SSH from starting as it marks itself as a prerequisite. This
service will never fully succeed as it tries to make a network
