It should be supported since 3.2. See http://www.ovirt.org/OVirt_3.2_release_notes So in current stable 3.3.3 it should be ok. take in mind that it depends on live snapshots, so limitation on RHEL / CerntOS 6.5 apply. In that case you should use the recent qemu-kvm rebuilt from jenkins job, as noted in other threads today: http://jenkins.ovirt.org/view/Packaging/job/qemu-kvm-rhev_create_rpms_el6/ HIH, Gianluca

can you do a live VM snapshot at all? If not then the QEMU you're running is not supporting it Thanks, michal

i.e. see "[Users] issues with live snapshot" thread:-)
