[libvirt] [Patch] Fix vcpupin to inactive domains on Xend3.0.3.

[Takahashi Tomohiro <takatom@xxxxxxxxxxxxxx>]

Hi,

I made the patch that corrected the following problem.
It is that when I execute the "virsh vcpupin" command to inactive
domains on Xend3.0.3,
Libvirt outputs the following Segmentation fault.

# virsh vcpupin guest_dom 0 0,1,2
Segmentation fault

Thanks,
Tomohiro Takahashi
