Eric Blake 6f66423e17 snapshot: allow halting after snapshot ... Since a snapshot is fully recoverable, it is useful to have a snapshot as a means of hibernating a guest, then reverting to the snapshot to wake the guest up. This mode of usage is similar to 'virsh save/virsh restore', except that virsh save uses an external file while virsh snapshot keeps the vm state internal to a qcow2 file. However, it only works on persistent domains. In the usage pattern of snapshot/revert for hibernating a guest, there is no need to keep the guest running between the two points in time, especially since that would generate runtime state that would just be discarded. Add a flag to make it possible to stop the domain after the snapshot has completed. * include/libvirt/libvirt.h.in (VIR_DOMAIN_SNAPSHOT_CREATE_HALT): New flag. * src/libvirt.c (virDomainSnapshotCreateXML): Document it. * src/qemu/qemu_driver.c (qemuDomainSnapshotCreateXML) (qemuDomainSnapshotCreateActive): Implement it.		2011-09-05 07:03:04 -06:00
