It seems you are right. Going to test, I tried to enable it on a CentOS 6.4 guest named "c6s" It seems all ok from a guest point of view (apart the tty that seems not to be automatically spawned from agetty or friend) I also read http://fedoraproject.org/wiki/Features/VirtioSerial But I don't know if this will be usable at this time from oVirt in any way....
