Many people collect things as a hobby. I collect computers. Over the years, as my collection grew, my living room began to look like a data center. As soon as VMware Server became freely (as in beer) available I knew I had to migrate my servers and development boxes to virtual machines (VM).

Out of the box, VMware can't properly shut down OpenBSD VMs; it just powers VMs off, causing data corruption. With a little bit of hacking, I managed to eliminate this issue. Here's how you can install OpenBSD as a guest OS under VMware Server, and possibly other VMware products.
