It might also be possible to use 'migrate' to migrate running memory info to a file in the background, and then when that completes use 'blockdev-snapshot-sync', as a way of cobbling together a complete snapshot even if you don't use qcow2 disk images. If you are using libvirt, then libvirt has wrapped these actions under its virDomainSnapshotCreateXML API. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org [-- Attachment #2: OpenPGP digital signature --] [-- Type: application/pgp-signature, Size: 620 bytes --] ^ permalink raw reply [flat|nested] 2+ messages in thread
