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?
This is included in the 'snapshot' APIs / virsh commands as of 0.8.1 libvirt release
Oh, excellent! (Alas, my libvirt 0.8.1 doesn't seem to think that my qcow2 images can support snapshots, but I"ll have to look into that some more)
You will need to set the driver type <driver name='qemu' type='qcow2'/> example: <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='writethrough'/> <source file='/var/lib/vm/data/images/debian.img'/> <target dev='vda' bus='virtio'/> </disk> Regards, Jason
