There are hooks in libvirt, to call actions when VM's are stopped or started. I've written a script (that is not perfect but working), that will lock all your rbd-images according to your libvirt-configuration once you start your VM. If you try to start the VM on another hypervisor (that has the same hooks in place) it will refuse to start the VM. I've documented and published my script on my webpage: http://www.wogri.at/en/linux/ceph-libvirt-locking/ > wogri > -- http://www.wogri.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
