The tutorial here still works to get your VM working in VirtualBox for FREE.... for Win 7

1. Download the trial of Parallels 7; and install Virtual Box
2. Uninstall Parallels tools from your virtual machine. Also take note of how much RAM and CPU, etc is assigned to the Virtual Machine in Parallels.
3. Shut down Parallels and your VM
4. Download trial of VM Ware Fusion 4
5. Import your Parallels Machine to VMWare Fusion 4 (takes over an hour)
6. Shut down VMWare Fusion
7. Search for .vmwarevm ... and Command-Left Click to open the folder containing the file.
8. Right click and hit "Show Package Contents"
9. Highlight all the package contents and copy and paste into Users/YourName/VirtualBox VMs/Win7 (You may substitute Win7 for whatever you want)
10. Open Virtual Box
Click "New" then "Next", then name your OS e.g. "Windows7" and choose the relevant settings on the two drop downs below (Try to match your original Parallels VM settings -- make sure your Windows 7 is 64 bit if you use 64 bit!!).
12. Now click ‘Next’, accept the defaults on the next screen and click ‘Next’ again.
13. On the next screen (headed as ‘Virtual Hard Disk’), click the ‘Existing’ button.
14. On the window that opens, click ‘Add’ on the top menu and browse to the folder you made in Step 9. Choose the file name e.g. Windows7.vmdk (don’t choose the numbered ones e.g. windows7-s016.vmdk) and click ‘Open’.
15. Back on the main screen now, click ‘Next’ again and then ‘Finish’.
16. Before starting your Virtual Machine, you may have to go to Settings...System..Motherboard... and put a check in Enable IO APIC
It's working great for me! I don't use it for gaming and it's just as fast as parallels for basic tasks.
As posted by another user... http://blog.carlossanchez.eu/2011/08...to-virtualbox/ has a great tutorial as well... with some trouble-shooting advice
