Obviously this a bit more "chicken-and-egg" than running a hosted 
engine.  Even if there was a "start automatically" sort of thing, this 
is still going to be fraught with potential issues, because almost 
anything could happen to prevent the "router vm" from starting.

I think you've created a fairly high risk scenario.

In other words, even if you got this working, I wouldn't trust it.

Just my opinion.  At a minimum I'd pull the "router" out of the VM 
stack.  Now, you could have a separate hypervisor cluster stack for the 
router, just don't put it's mgmt engine (separate engine req'd) behind 
the router :-)
