I see this has gone into xen-unstable and also the new qemu-xen tree[1].
But it would be nice to understand the compatibility properties:
* Evidently it breaks when tools have this change but qemu-dm
doesn't. Is there a way to avoid this being a fatal error ?
* I think I'm correct to assume that this change is harmless for
a new qemu-dm and old tools ?
* What about save/restore ?
Ian.
