I have a test xen installation that is using the gfx_passthrough option.
It appears to run fine. However, after about 15minutes the whole xen installation reboots for no obvious reason.
I don't see anything in the logs that would hint at the reason. How can I track/narrow this down? i.e. there is nothing logged in /usr/log/messages, or any of the xen log files.
Should I enable core dumps and try to debug?
