VB on Mac Pro won't boot

[joemac]

I have a Mac Pro with Bootcamp installed on a separate drive than Snow Leopard. When I try and start the VM, it errors with "No Bootable medium found". The drive identifier for my Bootcamp partition is disk2s3. I ran the terminal command sudo chmod 777 /dev/disk2s3 and have tried createrawvmdk with disk2s3 and disk0s3 with no luck either time. I have VB working on my macbook and have copied the settings from one to the other to hope it was something simple but no luck.

Does bootcamp need to be installed on the same physical drive as the host?? Any other thoughts as to what my problem could be?

Thanks
