Hi,
virsh has save/restore to do a one-time save+shutdown. But it does not expose kvm's savevm/restorevm, which let's me do incremental snapshots. Is there a specific reason why that is not exposed in libvirt, or is it just that noone has implemented it?
The save/restore API only does a memory snapshot. If you are referring
Jinkeys, I guess so - my first tests were confounded by the page cache being reverted and then synced back to disk :)
to the savevm/loadvm/delvm, which take a disk+memory snapshot, then that is implemented in terms of the libvirt snapshot API. You can start here:
http://libvirt.org/html/libvirt-libvirt.html#virDomainSnapshotCreateXML
Ok, so the snapshot created by virDomainSnapshotCreateXML is not what is used by 'virsh snapshot-create'? Are there any plans of exporting this through virsh? thanks, -serge
