I’m intrigued by what you said about proxmox. I’ve always run KVM and had multiple copies of my servers running behind a load balancer, but “clustering” sounds interesting. To me that word sounds like something that would allow high-availability to multiple VMs, possibly all running the same image so I don’t have to worry about tracking internal IP addresses and such… but I’m sure it’s not quite that simple. So could you give me a quick summary on what clustering really means in this case?
