Can I configure cores instead of CPU's

Hi All,

Scientific Linux 6.1 x64
qemu-kvm-0.12.1.2-2.160.el6_1.2.x86_64

My XP-Pro guest will only let me use two CPUs.

Is there a way I can tell Virt-Manager to use
one CPU with four cores instead of four separate
CPUs?

Many thanks,

Hi Frank,

Figured out what I was doing wrong. In virt-manager, Processor, as soon as I clinked on the "Copy host CPU configuration" button (Nelhalem, by the way), when I went to "topology", I was able to configure:
socket = 1
cores = 4
thread = 1
And, this time XP-Pro saw the cores as cores and not individual CPUs.

I even got fancy and tried
socket = 1
cores = 2
thread = 2
And that worked too. Yipee!

My mistake was not clicking on the "Copy host CPU
configuration" button.

Thank you for all the help in getting me there.

Happy Camper,
