So, I have a VM under ESXi and I'm just copying some files to it, to test it out.
According to the vsphere client, that VM is pegged on CPU on the two vCPUs it's been given on a quad-core physical box. (No other VMs running.) CPU usage = 100%. MHz usage = ~ 6,000MHz which is about two cores.
I log into the vm, do a mpstat, and it's basically 80% idle, 20% system. That's what I'd expect. It's not doing much.
So does the vsphere client simply report incorrectly?
