Yes, I think we are missing a xendomains init script, see as examples: http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=tools/hotplug/Linux/init.d/xendomains.in;h=dcd330cb8d5df137b493848bcde0b86f62c4acb1;hb=HEAD http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=tools/hotplug/NetBSD/rc.d/xendomains;h=edc4495317e7c97f77d295f3068647b07a871f5a;hb=HEAD That shuts down (or destroys) all guests when dom0 shutdowns. Regardless of this dom0 should not panic when shutting down with active guests. I will try to reproduce the issue on my end so that dom0 kernel doesn't panic. Would you like to try adding a xendoomain init script to FreeBSD? Thanks, Roger.
