To follow up, I am still seeing this problem.  It would seem to be a large bug in the stable release of Xen.

I set up my eight-domain virtual network again today, and I also connected the router to my (physical) workstation.  Then, nmapping my workstation’s subnet from my workstation causes my machine to reboot – same story.

 

I don’t understand why Xen is crashing like this…
