From: Peter Xu <pet...@redhat.com>
Currently we'll skip the whole migration-test if uffd missing.
It's a bit harsh - we can still run the rest besides postcopy! Enable them
when we still can.
It'll happen more frequently now after kernel UFFD_USER_MODE_ONLY introduced in
commit 37cd0575b8510159, as qemu test normally requires kernel faults. One
alternative is we disable kvm and create the uffd with UFFD_USER_MODE_ONLY for
all postcopy tests, however to be simple for now just skip postcopy tests only
by default. If we wanna run them use "sudo" or root, they'll still work. In
all cases, it's still better than running nothing for migration-test.
