This looks fine to me, and is consistent with the other features
we are enabling for the default qemu* machines.

What (if any) message is thrown by a kernel that isn't configured
with these features ? I suppose that since we aren't NFS booting,
you simply don't have ethernet, and the user can look at the
target's kernel config to diagnose that issue.

Cheers,

Bruce
