[libvirt] "virsh setvcpus" does not work.

[Ken'ichi Ohmichi]

Hi,

I tested "virsh setvcpus" command and it did not work like the following:

 # virsh setvcpus RHEL5.5GA_Guest.img 2
 error: internal error unable to execute QEMU command 'cpu_set': The command cpu_set has not been ound
 
 #

Has this problem been fixed already on upstream ?

o Test environment
  Host OS: RHEL6.0 (x86_64)
    qemu-kvm: 0.12.1.2-2.113.el6
    libvirt : 0.8.1-27.el6
  Guetst OS: RHEL5.5

o GDB output
  (gdb) b qerror_report_internal
  Breakpoint 1 at 0x497a50: file qerror.c, line 412.
  (gdb) c
  Continuing.
