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:

      <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.
