Can you explain what CPU priority is?
The amount of CPU resource a VM is given is the CPU priority (you can think of this as its “share percentage” multiplied by the number of cores allocated to that VM.
This is a minimum number – clients can burst over it, up to 100% multiplied by the number of cores. For example, on a hypervisor with 3GHz CPU cores:
100% x 1 core = 3GHz (burstable to 3GHz)
10% x 2 cores = 600MHZ (burstable to 6GHz)
5 % x 4 cores = 600MHz (burstable to 12GHz)
