Yes, that was my thinking.  It seems that oVirt requires updates more
frequently than users that use MOM with libvirt directly and the
Fedora update process is a bit more heavy than oVirt's at the moment.

If vdsm is finding this to work well than surely I can do the same
with MOM.  The 0.4.0 build is in updates-testing right now and should
be able to be tagged stable in a day or two.
