Run VMware Fusion headless at Mac OS system startup

README.markdown

Run VMware Fusion headless at Mac OS system startup.

I heard you like headless VMs on your Mac so I wrote this script for your launchds.

Assumptions

• Tested on Mac OS X 10.6.4 with VMware Fusion 2.0.5 and 3.1.1.
• A interactive user automatically logs into the system at startup. I had some issues trying to get this running without an interactive user logged in. I automatically log in for Airfoil Speakers anyway.
• Your virtual machines live in /Virtual Machines

Method

1. Place the vmdaemon script into /Virtual Machines and make it executable (sudo chmod 755 vmdaemon) and owned by root (sudo chown root:wheel vmdaemon).
2. Copy the template plist into /Virtual Machines. The plist should also be chmod 644 and chown root:wheel.
3. For each VM you want to run headless, copy the template property list file and change the filename, label and 2nd program argument to match your VM name.
4. Symlink the plist into /Library/LaunchDaemons
5. Run launchctl load -w $PLIST to start the VM.
6. Use launchctl unload -w $PLIST to initiate a graceful shutdown of the VM. By default it will wait up to 5 minutes for the VM to shutdown. This can be configured in ExitTimeOut in the plist

Forks and Feedback

If you try this out with your own setup, I'd like to hear how things go. Patches via gist forks are welcome.
