> From reading through the mailing list, it does appear that it's possible to have the ovirt nodes/hosts be VMware virtual machines, once I enable the appropriate settings on the VMware side. All seems to have gone well, I can see the hosts in the ovirt interface, but when I attempt to create and start a VM it never gets past printing the SeaBios version and the machine UUID to the screen/console. It doesn't appear to try to boot from the hard disk or an ISO that I've attached.<br>

</span>I wouldn’t think you can even get that far.<br>
It may work with full emulation (non-kvm) but we kind of enforce it in oVirt so some changes are likely needed.<br>
Of course even if you succeed it’s going to be hopelessly slow. (or maybe it is indeed working and just runs very slow)<br>
<br>
Nested on a KVM hypervisor runs ok<br>
