I had a crash on my desktop image that is running in a vm on proxmox. Since then it won't start anymore; a few seconds after starting it the host machine reboots.

It is still running 6.4 so I thought maybe upgrading to 7 would solve it so I wanted to make backups but when I run vzdump it also crashes after a few percentage of backup progress.

Any suggestions on how to debug and fix this?

thx!

it may show more , like hardware related stuff.

keep a couple of screens running something like the following.
Code: 
 journalctl -ef -p 7

Code: 
watch -n 10 dmesg -T

perhaps you'll catch something
