This looks good to me.  Would you mind sending a patch which updates
the rest of the configs similarly, so we can update all of the configs
at once?

As an aside, I *do* use the HW_RANDOM_VIRTIO from time to time (that's
why it was enabled in the config), and in fact kvm-xfstests is wired
up to supply the virtio random number generator by default (since it
doesn't really cost much):

if test -z "$NO_VIRTIO_RNG" ; then
    VIRTIO_RNG="-object rng-random,filename=/dev/urandom,id=rng0 \
	-device virtio-rng-pci,rng=rng0"
fi

But that's for my kernel RNG testing, and it's fair to say that that
most users of kvm-xfstests won't need it.

Thanks,
