And no state of the <domain> at the time the checkpoint was created?
I meant to add: once we start playing with checkpoints vs. external snapshots vs. hotplug in anger, then knowing WHICH disks existed at the time of a given checkpoint may prove invaluable to even figure out WHICH disks need to participate in a given backup operation. The initial implementation uses XML (so that adding features can hopefully reuse the same API, rather than needing yet more one-off API additions), even if it is currently limited to not playing nicely with snapshots. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
