Physical core vs vCPU in OVM

TatyasoOct 28 2015 — edited Nov 2 2015

In OVM document for hard partitioning or pinning the CPU, I read that, If the virtual machine has 4 virtual CPUs, and you put cpus = '0' in the vm.cfg file, then all 4 virtual CPUs will be scheduled on the same physical core. @https://docs.oracle.com/cd/E26996_01/E18549/html/vm_hardpart.html.

I am little curious to know,If VM has more vCPUs than pinned cores, does it help to get better performance? Or it is better to match with no of pinned cores?

Is there any recommended approach to define/design vCPUs for VM?
