I sure thought that I was doing when I set this on the host:
And the XP VM only had one CPU simulated within it.
Keep in mind that this was many months ago when I was using an XP host with two physical cores. The CPU scheduler in XP doles out time slices in a round robin fashion... which means if the VM is maxed out, then each CPU is running at about 50%. The host was noticeably slower if I did not "dedicate" one physical core to the multiple VMs. Sure the host still could make requests of that same physical core. I did not work thru each process and force them to use the second physical core. Had I done that, then one physical core would have been dedicated to the VMs.
I realize that the OP is talking about a Windows 7 host with an AMD CPU with 8 physical cores and that the Windows 7 CPU scheduler is different than XP's... but, even within Windows 7, you can "dedicate" a CPU to a VM. It might not be wise, but it can be done and might be best for some setups.
