I have moved my minecraft server to a proxmox cluster running under ubuntu server using a simular process descibed above to set it all up. I have to say, having had the chance to play around with proxmox for a while now, it really is a great choice for VMs. If you can get a backup server running as well (can be run as a VM on truenas scale) you have a really SWEET home lab solution. I have been using a bunch of HP elitedesk minis as a proxmox 2 node cluster with a 3rd machine acting as a backup server, I also have home assistant with a coral TPU USB stick as my home assistant server. What a world we live in where I can get thses machines for $150AUD each. =D
