[libvirt-users] virsh create failed: cannot set CPU affinity on process 0

[杨镭]

Hello Everyone:

We can't create vm on a physical server with 64 CPU(as reported by
/proc/cpuinfo). The error message is: "cannot set CPU affinity on process 0"

The following is the capabilities detected by libvirt:

      <arch>x86_64</arch>
      <model>Westmere</model>
      <vendor>Intel</vendor>
      <topology sockets='4' cores='10' threads='2'/>

I wonder if libvirt uses incorrect CPU topology information to set process
affinity which lead to the error above.
