CPU > VCPU in VM Template

Hi,

Does anyone know of a situation where it is reasonable to have the value of CPU greater than VCPU? In my understanding this is just blocking (say wasting) physical CPU resources.

In general it is better to think about VCPU and CPU as separate metrics.
CPU is to hypervisor allocation and over commitment, so for example CPU >
VCPU may let you to not place other VMs with a given one. For example you
if you have hosts with 8 cores, you could define a VM with VCPU=2 and
CPU=8; it may not use all the resources in the hypervisor but you also
prevent contention.
