Just curious.
Why do you run multiple boxes attached by KVM, when you can just run VMs on one? Would use alot less space, and multitasking between them would be MUCH easier.
Pretty much agreed on that. You need lots of RAM to do VMs well though. I've got 18GB, and I can run vms pretty much to my heart's content. Would hate to try to do that on a 2GB box.
RAM is cheap though. I recomment 8GB minimum if you're planning on stressing your computer. One of these days, I still plan on maxing my box out at 24GB. Even with 18GB, I've managed to max my box out a couple of times. (Pegged all 8 cores, and all 18GB GB of ram doing some statistical analysis of some rather large data sets.)
