Also, try running "xm info" on your dom0 - one of the lines should be "nr_cpus" which should tell you how many CPUs the Xen hypervisor is seeing.

Hi all,

 

     On dual core processor machine, I installed ubuntu-8.04 in which I installed xen-3.2.

   In ubuntu:

   # cat /proc/cpuinfo à Shows two processors information.

 

  But in Xen on the same machine:

  # cat /proc/cpuinfo à Shows only one processor information.

 

Can anyone please explain what could be the reason behind this?


I don't think I would expect this to be the case.

Just to clarify you have a dual-core, single processor system (two cores on a single chip) right?

How did you install Xen 3.2 on ubuntu, which kernel are you using?
 
Is one of your kernels SMP on the other not SMP?

Cheers,
Todd
