XenServer - All VM's off?
-
So about once every 2 weeks, I logging to XenCenter, and all my VM's are off
Is there a log or something I can read to find out what is happening?
-
Have you checked /var/log/xensource.log? kern.log?
-
I don't see anything interesting in there, but then again not sure I would know if I did
-
Sounds like the server is rebooting...
-
@Danp That's a really good point..... Maybe a power outage.
I'll hook it up to to battery backup and see what happens
-
@anonymous Why would you be running without a battery backup?!
-
What is the uptime on the XenServer?
-
@scottalanmiller 2 Days, but I can't remember if I rebooted it or not
-
@Danp Adding my server to the battery backup overloaded the battery backup, I have to get a larger one ASAP.

Check last to see what was done.

history is another good way.

Only for your shell session, though. If another shell did it, you can miss it.

You can set VMs to run at boot too. That doesn't solve the issue but it could alleviate some downtime.

Although if this isnt production, I would wait to do that until you have this resolved or it might hide the issue from you.
Look at monitoring solutions too, so you know right when things happen.

There has been a bit of discussion of Zabbix and ELK recently. Those would have caught something.

Agreed.

Setting them to start at boot breaks HA and isn't recommended.

Why do you assume that he has HA?

Graphical log analysis for the win...

I'm not assuming he does, I'm just putting the information out there that the Xen Teams have it disabled by default and the reasoning behind it.
