I just want to clarify terms here.  oVirt Node is a complete livecd
based image.  You don't install ovirt-node on a running system, you
build an image with it installed and then run that image.  

With that said, ovirt-node does have similar problems w.r.t. networking
configuration, etc.  It directly
manipulates /etc/sysconfig/network-scripts/* and probably has other
stuff as well that is Fedora specific.  Adding a dependency on systemd
is not really applicable in this case, since it's a pre-built image.  

You sounds like you're interesting in vdsm directly, not ovirt-node.
