Hi, If i take a snapshot of a qcow2 image backed domain via virsh snapshot-create domainID and I shutdown the machine (and probably destroy the domain if virsh list still shows it running), and then undeinfed the domain will that snapshot still exist and be active when I define and start the domain back up? --- Thanks, Yitao(依涛 姜) jiangyt.github.io

Shutdown/destroy does not lose track of snapshot information. Undefine does; but it only loses track of the metadata; the snapshot data still exists, and you could re-create it with virsh snapshot-create --redefine after the domain is redefined, if you want to still revert to that state. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
