There's currently no OS level test for ppc64le. Add one such test by
reusing the boot level tests that are already present.
The test boots the source machine, waits for it to reach a mid-boot
message, migrates and checks that the destination has reached the
final boot message (VFS error due to no disk).

Hi,
this is not how to use the context for Ports: Once the "with" block is left,
the locking for the free port will be gone and you're subject to a race
condition with other tests running in parallel (see the __enter__ and
__exit__ methods in tests/functional/qemu_test/ports.py ... and yes, there
should be more documentation for this).
You've got to put everything up to the point where QEMU takes the port into
the "with" block, i.e. everything up to including the Migration().migrate()
line.
