John Martellaro, on The Mac Observer, posted an article with links to Parallels knowledge base articles explaining how to do this. You'll need to update Parallels Desktop, then create a snapshot of an existing virtual machine and install Mavericks on that.
For VMware Fusion, the process is quite simple: take an existing virtual machine, running 10.7 or 10.8, duplicate it in the Finder, then launch VMware Fusion. Choose File > Open, then select the duplicate virtual machine. Rename it, then launch it. Fusion will ask if you moved or copied the virtual machine; click I copied it.
After you've launched the duplicated virtual machine, run the Mavericks installer from within that virtual machine.
Note: as always, we will not be publishing hints about using OS X 10.9 until its release.
