How to install 3150 over 1970?

I tried to install 3150 over the 1970 release, and my Windows XP image is not starting up (hangs with black screen).

How did you do it? Interested especially if you got it working ;-)

It's been discussed at length. The summary: Using 1970, uninstall Parallels tools. Then install the beta, reboot, start your VM and install Parallels tools.
