If a qemu sends data larger than the field, the source side is already compromised. All we care about is that the destination fails gracefully, rather than acting on the bogus information from the compromised source. Versioning is only necessary for correct migration data, and doesn't matter when the source is already compromised. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
