Not if you want to use ovirt-node with ovirt-engine. There was a bug in that patch set that is fixed in patch set 2 (along with the bad ===== package). I hadn't pulled the patch set together and uploaded to gerrit yet, but it's there now. git fetch http://gerrit.ovirt.org/p/ovirt-node refs/changes/38/1738/2 && git checkout FETCH_HEAD This should fix the problem.
