That would explain it, it's the attempt to use KVM that triggers the
problem.
Obviously it's not a thing to fix right now, but I've really been
thinking that none of the tests should use this "TCG or KVM" stuff.
They should instead be run with *both* options - or at least the ones
that are available on the host.
That would have caught the bug in the pull request I sent you, and
would at least have given you a chance at seeing the problem with
boot-serial-test.
