I have always been a huge fan of VMWare Workstation. “The basic idea is that it lets you run a whole PC inside a window, with its own operating system and hard drive.”
I’ve dreamed of the day when I could use something similar for servers. VMWare has had a couple of server products for a while now, GSX and ESX, but they were expensive and complicated.
No longer. VMWare Server is going free. Wow. Mike Gunderloy explains why this is “a market-changing move.” This is great stuff, and it’s not half baked.
