Two suggestions:

- when vcpupin an inactive domain, it gives an error message like this:

  error: Requested operation is not valid: cannot pin vcpus on an inactive domain
  
  After applying this series, this is not true anymore. I think a
  message like this is more helpful:

  Failed to pin vcpus on inactive domain, please check the --config option.

- While it can vcpupin an inactive domain, it seems reasonable to be
  able to view vcpuinfo of inactive domain, so would a patch to
  vcpuinfo command be included?
