Hello Jeroen, So it looks like the system rebooted (but it was not a crash or a sporadic reboot? the kernel seems to be aware of the reboot request). It would be interesting if you could provide the output of the serial console when this happens, that might be helpful. Did you enable xenconsoled logging? Also, could you provide more info about your system, Xen version, what workload was the DomU running, Dom0 kernel version?
