3Ghz. What i'm trying to do is reserve CPU resources on one particular server to see what the maximum is that I can get to a VM.
1 VM with 1 vCPU is 3GHz, same as a physical processor. 1 VM with 2 vCPU is 6GHZ, 1 VM with 4vCPU is 12GHz, it's simple math. The vCPU is tied to the equivalent of 1 CPU on the host system, unless you throttle the CPU, that is what you will get, no more, no less.
Reserving resources only means that the ESX server sets aside that amount of resource, that once it's been utilized by the VM or pool, it can't be used for any other purpose, even unless you shutdown those VM's.
I've put that into its own resource pool so that nothing else is on the server. I only seem to be able to set a CPU reservation of around 12GHz.
That's correct you have a Dual Core / Dual Socket mahine. Math: 2 Dual cores (3Ghz each is 6 Ghz), 2 Sockets with 2 6GHz processors is 12 GHz, so where do you get more than what your host system has? You can't allocate more resource than you have physical resource, so no you can't reserve more than 12Ghz processor.
I should be able to reserve up to 24Ghz (8 CPUs @ 3Ghz).
How do you figure? You only have 4 logical processors, of 3GHz each, where are you getting this number?
