When thinking about something like ovirt-node, my concern is that a jboss7 
based 
ovirt-lite would end up significantly impact the size of the image.

I think ovirt-node tends to be around ~100MB today which includes VDSM.  A 
simple REST API (as Adam proposes) wouldn't increase this size at all.

Just the openjdk package looks to be around 72MB.
