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.
