In principle an ovirt-engine-light sounds great. Especially if we could get the existing GUIs for free. The main concern I have with this is the gargantuan nature of the ovirt-engine and GUI code bases. You want to reserve as many system resources for the guests but it seems that ovirt-engine will consume at least several GB of RAM and one or more CPU cores. How would you lighten up this JBoss stack without rewriting it in a more efficient language? One use case I am interested in is a single-node ovirt instance to control VMs on my laptop. I can spare several hundred MB of RAM at most for the management stack.
this is much much lighter and faster with jboss7 (which iirc, takes 100MB to start, tomcat takes 80MB for comparison).
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.
