We wan't to setup two Oracle instance and make RAC work on them. Both VM are setup based on libvirt + KVM, we use a lvm lun which formated in qcow2 format and set the shareable properties in the disk driver like this:

qcow2 is not cluster-aware, it cannot be opened by multiple VMs at the same time. You must use raw. Stefan
