Hello ### http://www.redhat.com/archives/libvir-list/2012-July/msg00782.htm "it almost sounds like you want the convenience of a system checkpoint (the ability to revert to a guest with its RAM state unchanged, which is much faster than booting from just disk state)." ### I am trying to figure out if it is possible to take a snapshot or "system checkpoint" for a VM running on a centos 6 host. I am able to take a snapshot but unable to revert. Force revert will cause the VM to become unresponsive. Nothing would show in console after revert. My host OS environment is CentOS release 6.4 (Final) libvirt-0.10.2-29 qemu-kvm-0.12.1.2-2.415 virsh # suspend combo01 Domain combo01 suspended virsh # snapshot-create-as --domain combo01 combo01-snap1 "snap1-desc" --atomic Domain snapshot combo01-snap1 created virsh # snapshot-list combo01 Name Creation Time State ------------------------------------------------------------ combo01-snap1 2013-12-14 20:57:41 +0000 paused virsh # snapshot-revert combo01 combo01-snap1 error: revert requires force: Target device address type none does not match source pci virsh # snapshot-revert combo01 combo01-snap1 --force virsh # list Id Name State ---------------------------------------------------- 8 combo01 paused virsh # resume combo01 Domain combo01 resumed virsh # console combo01 Connected to domain combo01 Escape character is ^] The VM became unresponsive at this point. _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
