Changing the hostname of a Proxmox 8 VE

I tried changing the hostname using hostnamectl and editing the hostname in /etc/hosts but that broke the node completely and the panel showed up empty upon login. I changed back to the old hostname and rebooted and everything's fine now.

I already read the doc and it says that hostname may only be changed if a node has no VMs but I already do have a few VMs and want to change the hostname of the node, what is the correct/official way to achieve this without breaking anything?
