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

[Jason Keltz]

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.
