Hi. On the current pc I have a core duo2. The processor settings dialogue in Vbox can only see 1, and doesn't allow me to select the max: (2 in this case). Is there something wrong or thats the way it works? I've noticed when running vmware player that there the 2 cores could be selected. So I'm wondering if it just appears that they are or if the other program is also using 1 processor.

AFAIK vbox's SMP support means more physical cpus can be used for the vm. Correct am I?

Your input is appreciated.

At first your machine (CPU+Bios) must have VT.

At second it makes no sense, because you are running 2 os and not one.

Thanks for the reply. So that means that 1 processor is the maximum that each OS oculd have? So the workload cannot be shared by 2 processors like any other program? I'm sorry for the questions but I'm a little confused.

That is correct. If your hardware and BIOS do not support hardware virtualization, you can only run one processor per vm.

But if you are running two vms and the host OS you are already running three OSs. Giving one vm two processors whould not really be much of a benefit. You two processors are already stretched.
