Ubuntu 8.04 on VMWare Player

I've been working on getting an Ubuntu virtual machine running on my Ubuntu laptop so that I could test things without messing up my main laptop, and was having a very difficult time getting things working right. The biggest problem is that the keyboard repeat rate appeared to be set very fast, and each time I hit a key, I'd get multiples of that key. I found a blog entry that seems to have helped:

This entry basically says that you should add acpi=off to the kernel line of your guest OS.
Worked great for me!
