In your config file you can specify:
on_crash = "preserve"

This will stop the domain immediately being rebooted when it crashes. It
will hang around so that you can connect to it via 'xm console' and see if
there is a crash dump there. Also you could 'xm dump-core' it and then
perhaps use crashkernel tools to pick apart the coredump.
