Hey David,
stateless is a feature or a special mode of oVirt Node which is also
available on the "oVirt Node for oVirt Engine" image [1].
But please note that you will have to approve the Node in Engine after
each reboot if you use the stateless feature. This bug [2] might also
tackle the problem of a stateless Node.
