[ovirt-users] several ovirt questions - CPU allocation, and use threads as CPU

Hi. When I go to the "Clusters" in ovirt engine, I can see the total number of VMs in the cluster. If I open up "Hosts", I can see how many VMs are running on each host. I can see the memory consumption as well. How do I go about seeing how many CPUs I've allocated across all the VMs on a host? What happens if I allocate more cores than what I actually have? If shared CPUs are possible, can I specify VMs that are allowed to shared CPUs versus VMs that reqiure dedicated CPUs? Finally, I presently have "Use Threads as CPUs" off. I don't remember if that was the default, or whether I selected that option during installation. Is there any disadvantage to turning it on? I realize that those other cores aren't "real" cores - they're the hyper-threading course, but it's not clear how ovirt would handle those cores. If I specify say, a dual CPU system, would that system show up as 4 cores (2 real cores and 2 hyper-threaded cores) ? Thanks for any help.. Jason.
