Thanks, I like Ubuntu Server as well. If it's good enough for Facebook (so I've heard, at least) it's good enough for me.
I currently run Ubuntu desktop 10.04, and several Ubuntu Servers in bridged VirtualBox vm's for development, which lets me simulate a multi-server production environment on my desktop.
However, I've been thinking about switching the desktop to Arch using Xmonad or i3, and KVM for the vm's (keeping Ubuntu Server).
Any experience running KVM on Arch? Assuming there's no issues with it.
