For those of you interested in Linux under Microsoft Virtual PC 2007...

...there's a 'quirk' with Virtual PC that can make it difficult for the installer (in my case OpenSuse 10.3) to detect your mouse/keyboard properly, to get around this try adding the installer boot option "i8042.noloop" (minus the quotes of course.)

Also, if you're mounting the install from an ISO, this can be problematic as well. If the install keeps asking you to put in CD1 (or any type of media it shouldn't be asking for), try burning the ISO to disk and asking Virtual PC to let the virtual machine grab the CD/DVD drive as this fixed some problems I was having as well.

I hear that you need to change the framebuffer's color depth to 16-bit (from the default of 24-bit) after install as well, but we'll see about that later...
