You don't actually need a running OSX install.
You can use
DMG2IMG to convert the disk image to ISO format.
Then using the free Player, run the unlock tool. Create a new VM, selecting Apple OSX as the OS type and select the version of the OS from the dropdown menu.
Attach the newly created ISO, and then boot and install the OS as you normally would (making sure you use Disk Utility to set up the OSX Partions before installing).
I just did this, using 10.8.2. Ran system update to take it to 10.8.5, no issues. Audio works out the box.
AIR.
