Hi,

Your compute nodes reboot or are shut off?

I am currently looking at some cases where VMs seem to spontaneously shut themselves
off. At least from the nova logs’ perspective there is no difference to a normal shutdown,
VM owners however confirm that they did not touch their VMs. So far I was unable to
explain this.

This is with Havana on a RHEL6 derivative, though.

Cheers,
 Arne

Everything works just fine, but... the compute nodes reboot themselves periodically, sometimes every 2 weeks, some times once a month. I've done almost everything I can think of: memory checks, analysed the logs, moved all the VMs to one node, and I just can't find the problem.
