Ah I see, so if you enable it in the BIOS but without loading the module in the Dom0, then it will think the dead man switch is triggered and you are in for a reboot, I see Thanks for sharing your experience anyway!

If I'm being honest here I don't really find the messages as annoying as you are making them out to be. Sure if I had a choice I would want them gone, but it's really not a big deal, 1-2 clicks and they are gone until the next time I login. I also kinda like the reminder on the sidebar about no support, helps me remember that A. I'm in my lab environment and B. I'm using a from the sources version so I need to manually do updates etc.....

That would be interesting to get some pointers (like serial debug and so on). I wonder if there's already some resources for Xen Project somewhere
