Subject: [PATCH] util: Propagate numad failures correctly

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

Right now, if numad fails, we raise an error but return an

empty string to the caller instead of a NULL pointer, which

means processing will continue and the user will see

  # virsh start guest

  error: Failed to start domain guest

  error: invalid argument: Failed to parse bitmap ''

instead of a more reasonable

  # virsh start guest

  error: Failed to start domain guest

  error: operation failed: Failed to query numad for the advisory nodeset

Make sure the user gets a better error message.
