Hi! I'm try to grep sources, but can't understand, how libvirt create internal snapshot in the same qcow2 file without memory state? As i understand libvirt via qmp/hmp runs savevm command via qemu. But i don't understand how libvirt skips memory state in this case?
You could possibly do that with 'blockdev-snapshot-internal-sync', but libvirt doesn't support that yet. Internal snapshots are always with memory state if the VM is online at the time the snapshot is taken. Peter
