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:

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

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