One of the really nice things about the VM description format is that it goes over the wire when live migration is happening. Unfortunately QEMU today closes any socket once it sees VM_EOF coming, so we never give the VMDESC the chance to actually land on the wire. This patch makes QEMU read the description as well. This way we ensure that anything wire tapping us in between will get the chance to also interpret the stream. Along the way we also fix virt tests that assume that number_bytes_sent on the sender side is equal to number_bytes_read which was true before the VMDESC patches and is true again with this patch.
