Not entirely certain this is the right forum, so Mods, feel free to move this at your discretion.
I've currently got 2 computers sitting around, and I'd like to use one of them for a 24/7 modded Minecraft server for me and some friends, or a server I can quickly and easily set up temporary servers for other games on.
The rigs:
One is an HP xw8600 workstation with 16GB of DDR2 and 2 Xeons. They're each dual core, I don't remember the model number, but they're pretty old. It also has dual gigabit ethernet ports, whereas the other only has one. The BIOS supports virtualization, if that means anything to a Linux system.
The other is one I made myself. Its got an 8350, and 8GB of DDR3.
The graphics cards in each are pretty sucky, so I left them out.
Power consumption isn't really a concern, and I could put any OS on either of them. I was thinking Proxmox and then running a VM of CentOS or something. Any recommendations for an OS?
And a final question, how much would running a VM in Proxmox impact performance?
Thanks for any help!
