I've never had performance issues with Linux in a VM. Barely slower than running it dual booted. I mean, I run light WMs (originally AwesomeWM, but the past year or two I've been using xmonad). But I don't remember the interface being slow when using, say, Gnome 3. The only things I can think of that might be special about my setup is that I generally: 1. Run the VM off of a different physical disk than the host OS (only necessary if you're using HDDs) 2. Allocate generous amounts of RAM (4-8gb) even though very little RAM is required. 3. Use machines that have 4+ cores.
