Fedora xen - Apr 2006 - RE: two fully virtualized systems crashing

Sorry, black screen meaning that all VGA output is disabled.

And generally if there''s a kernel panic or something core dumps
there''s a
log to trace the errors back. In this scenario there isn''t.

And I should clarify the reboot as well, its not a software initiated
reboot, it''s a hard reboot.

Admittedly very odd!

Thanks,
-Alex

The original problem described a spontaneous reboot, not a "black
screen"
(what exactly do you mean by that, btw?  The screen saver kicks
in?)  And what do you mean by kernel dump info --- HV VGA output, dmesg
logs, or what?

Thanks,
 Stephen

In that sort of situation, serial console is often the best way to try
to capture information when using Xen.  I''ve just added a section on it
to the FC5 Xen wiki:

        http://fedoraproject.org/wiki/FedoraXenQuickstartFC5
        
which should be helpful in setting this up.

Thanks,
 Stephen
