libvirt users - Jan 2011 - Allocating Sockets Cores and Threads.

Hi,

Is there any other way I could allocate sockets, cores and threads to my
virtual machine? I looked over the virsh man page and I didn't find anything
that talks about sockets, threads and cores.
I edited the vm xml file and added this...

<cpu>
    <topology sockets='1' cores='2' threads='1'/>
 </cpu>

Saw this in the libvirt documents, http://libvirt.org/formatdomain.html

Setting this up shows me a single core in my vm, but I don't see any sockets
and threads. Can somebody tell me how to do it in a right way so that I see
all sockets, cores and threads allocated in my vm.

Thanks
joe

I'm checked out my /proc/cpuinfo file and I'm finding the following
changes.

Physical ID : 0
Siblings : 1
core id :0
cpu cores :1
apicid :0
initial apicid:0

This is what I noticed when I edited the vm with this ...
<cpu>
    <topology sockets='1' cores='2' threads='4'/>
 </cpu>

Thanks
Joe
