Here are the Macs that can run Mountain Lion:

iMac7,1 or newer- MacBook5,1 or newer- MacBookAir2,1 or newer - MacBookPro3,1 
or newer - Macmini3,1 or newer - MacPro3,1 or newer - Xserve3,1 or newer

If your Mac isn’t on this list (or has an older model number), then regardless 
of its age or speed, it won’t run Mountain Lion.

I am running Parallels Desktop 8 in Mountain Lion, but Parallels Desktop 7 will 
run if you have updated to the latest build 7.0.15104.778994

I am going to update to OS X Mountain Lion, what should I do to prepare 
Parallels Desktop 7 before?
1) Launch Parallels Desktop 7

2) Go to the Parallels Desktop menu and click “Check for updates”

3) This will download the latest build (Parallels Desktop 7.0.15104.778994, 
released on July 10, 2012) for you.

As long as you backup and do the preparation before upgrading and after 
installation completes.
You might like to check out my Tutorial "“Prepare For Mountain 
Lion-Installation-What to do after Installing”. 
If you find the tutorial helpful I would greatly appreciate a donation.
