DANGER: This will delete ALL of your container & virtual machine configurations, so unless you want to spend the next however long recreating everything, do not do this!

and even broke my ability to log into the box, at all.

This should really have a warning attached to it.

if you don´t want to remove every node you can just edit this command.

rm -rf /etc/pve/nodes/%node%
