All virtual machines Stopped

[Miguel Alfaiate]

Hello.

I just noticed that all of my hosted virtual machines were stopped in pve.

I did not issue any stop, and they have been working flawlessly for several months.

When I opened the web interface, all of them were stopped. I was able to restart the machines successfully, but I am afraid that something might be wrong which caused this problem.

I would like to know where can I find log files related to proxmox that might help me trace down the problem. Service logs that might contain indication of a service going down, machines being stopped or anything else. Or if there were any updates that ran and the services were unable to restart afterwards?

Can anyone point me to where I should look first? (actually my first attempt was looking at the auth log for login attempts, nothing weird there).

These are all linux vm's (no lxc containers).

Any hints in /var/log/syslog?

Hello Dietmar.

In the meanwhile I figured out there was a power issue in the datacenter, so the server was out and it was rebooted afterwards. What happened is that Proxmox rebooted but not the virtual machines.

Is this some sort of configuration, how can I set which machines should automatically start? I see a "Start all vms and containers" entry in task history, but none of the machines booted.

Just set "VM/Options/Start at Boot" ...

Thank you,

I looked for that in the datacenter and server menu and did not see an option for setting the auto boot, did not search in the individual machines' settings.

Problem solved.
