For what it is worth, I've been able to convert the QNX 650 VM to run under Parallels.

I had to do it under Ubuntu Linux.  Here are the steps in general.

1.  Combine the split disk images into one image:

vmware-vdiskmanager –r ~/VirtualMachines/<imagename>.vmdk –t 2 ~/VirtualMachines/<newimagename>.vmdk

2.  Install qemu
sudo apt-get install qemu

3.  Convert the vmware harddisk image into a raw format
qemu-img ~/VirtualMachines/<newimagename>.vmdk -O raw ~/VirtualMachines/<newrawimagename>.hdd

4.  Copy everything to your machintosh computer and start up parallels

5.  Open the virtual machine, let it do its converstions.  It will complain about an invalid image, as with most things 
that complain, ignore it :)

6.  Open up the hardware settings of the VM, change the image for the HD to the raw image you created with qemu-img.

7.  Start it up and hit the space bar, make it boot w/o photon

8.  Get a command prompt and type:

touch /etc/system/config/nophoton

9.  Reboot and it should work.  I think the video driver kills the VM when QNX tries to start it.  

Let me know if it works for you, or if you have some problems, I'll try to fix them.

Thanks
