Well, one which cannot resume from a snapshot at all unless you have
the original host and original QEMU/KVM around is pretty bad.

I've already been bitten by that, and had to throw a useful guest
snapshot away because of it.

But I've also been bitten by it resuming in a faulty manner across
QEMU versions, so I appreciate both points of view.
