Right now, there is no way savevm versioning can be compatible with upstream

the versions.

If you assume that KVM will eventually merge into upstream QEMU, this means that
eventually KVM is going to have to break backwards compatibility with itself
to resolve this issue in a non-graceful way.

So let's do that now instead of doing it later when the situation is only worse.

I'm happy to allocate particular version identifiers for KVM to avoid future
conflicts.  I believe we should try to eliminate the existing differences so
that we can converge in the future on a common versioning scheme.

Applied both, thanks.

I think we can avoid the need to synchronize too much by saving kvm-specific state for device "x" using id "x-kvm"; this allows the two to evolve independently. Of course it's much better to avoid divergence in the first place, but this isn't always possible.
