After a blackout, most of my VMs will not start up anymore. As I am fairly new to Proxmox, I am a bit unsure, how to debug this situation. Any help appreciated. The VM I am most concerned about shows this log entry:
Code: 
Mar  3 17:56:07 server qm[50948]: VM 114 qmp command failed - VM 114 not running

Thats why you should always power a server by a UPS which you get new for as low as 50€.

Whats the error message you get when starting the VMs (double click the log at the bottom to see a more detailed error message)? Can't PVE start them at all or are the VMs starting but won't boot?
 
Found the reason:
Code: 
qm start 114
says:
Code: 
volume 'local:iso/ubuntu-21.10-desktop-amd64.iso' does not exist
That is very strange, as I worked with that VM an hour before the blackout.
 
So you ISO is damaged/lost. But you don't need that iso after installation anymore, so you can go to your virtual CD drive and choose "do not use any media" and it should start again.
