[ovirt-users] Is oVirt suited for supporting long-lived VMs than OpenStack?

Hi guys, I'm wondering why people say oVirt is better suited for traditional workloads like long-lived VMs than OpenStack. does oVirt have some additional features for it? Of course, VMs in OpenStack might be intentionally killed according to resource pressure if auto-scaling is used. but otherwise, I guess OpenStack has enough to run long-lived VMs. thanks.
