Sorry, this is a stupid question but I'm just trying to wrap my head around CPU MHz distribution, and by that I mean, how much processing power is a virtual machine able to draw, given that there are no reservations/resource pools/no DRS.
So the question is this.
-ESXi host has 12 x 2.49 GHz Processors(dual 6 core procs)
-A RHEL VM has 2 vCPUs.
When the VM comes under load, can it utilize all of the processing power on the host(12x2.49GHz), or only the 2x2.49 GHz because it only has two vCPUs?
I guess a follow up to the question is, would adding more vCPUs help with more processing power on the VM? I can only assume it must since I've seen high performance VMs with multiple procs, however, I thought that in some cases multiple procs increased %ready due to CPU scheduling.
Maybe there is an up to date doc that would explain this?
