I'm using multiple virtualization products on my MacBook Pro (VirtualBox, VMware Fusion, Parallels). To avoid problems I always make sure only the procesesses/kernel extensions for one of those products are running.

For VirtualBox you can run:

sudo /Library/StartupItems/VirtualBox/VirtualBox start
sudo /Library/StartupItems/VirtualBox/VirtualBox stop

For VMware Fusion 3:

sudo /Library/Application\ Support/VMware\ Fusion/ --start
sudo /Library/Application\ Support/VMware\ Fusion/ --stop

Is there a single command or script to stop/start the Parallels stuff? Currently I am running multiple 'launchctl' and 'kextunload' commands.

By the way: VMware Fusion 4 does load/unload of the kernel extensions automatically when you start/stop the application. No necessary. The stuff in "/Library/Application Support/VMware Fusion/" isn't there any more anyway. – Paidhi Sep 25 '11 at 13:42
