Hi,

I’m currently running node on HP ProLiant with 2 x Xeon with 4 core each. Because of hyperthreading each physical core is being seen as 2. How KVM/oVirt reserves cores if for example I allocate 4 CPU cores for VM ? Does it allocates 4 real CPU cores, or 2 cores with 2 threads each ?

Depends on how you've configured the host and the VM.

Each VM consumes very low CPU resources. What happens if # of used cores consumed by VMs will exceed real count of physical CPU cores ?

If they are really consumed, the VM might be slowing down considerably. Y.
