Why one VCPU is 100% while the other one is 0%
When I assign two VCPUs for a VM, and then run some CPU intensive applications in that VM,it always turns out that utilization of one of the VCPUs will be 100% while that of the other's is nearly 0%.
Can anybody explain why it works like this?
Thank you.

Maybe the task you are running is not multi-threaded ? I'm assuming the vm OS can see 2 cpu's ?

Also, is the host operating-system a multiprocessor build? Do you ever see the second VCPU being utilized?
