Hi All,

I am a new user to Xen and Virtualization from the point of view of running the Host machine. I had an incident on my server this morning that I would like some advice on. I have joined this mailing list as it seemed the most fitting but please let me know if I should place my question somewhere else.

At 08:27 this morning my Dell r710 that is running Xen 5.6.0 and has about 15 VMs on it decided to reboot. I learnt my lesson about not using the auto-boot option in Xen Center and this meant that my machines were down for about 15 mins before I logged back in and restarted them.

I have started looking at the logs to see why the server rebooted but I am having trouble understanding where I should look and what I should look out for. I am happy to post the relevant bits from the logs here if that helps. So far I have only looked at the logs that XenCenter knows about. Should I actually look at the Xen box via the CLI and check the Linux logs? If so which ones?

Thanks in advance for any help you can give me on this.

Thanks
