I'd guess that isn't hard. We already have QEMU qcow2 snapshotting support on qemu-xen working via direct calls to QEMU - I think it 'worked just like kvm'. I seem to remember there is some fiddling to do with an open fd number in qemu for the live rebase, and some limitations (for instance I couldn't see how to do a consistent snapshot of the same device presented both pv and emulated under HVM - which is theoretically an issue if you have one partition mounted one way and one the other). -- Alex Bligh _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
