The Question

How do i start this Wiki VM at the startup of the OSX Server?

I am running OSX Server 10.6.8 and VirtualBox 4.1.8 r75467 and a Debian Linux VM (called "wiki").

.

What I tried so far

Following this article: http://mikkel.hoegh.org/blog/2010/12/23/run-virtualbox-boot-mac-os-x/, i have wrote this plist and placed it in /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist:

<plist version="1.0">
<dict>
    <key>Label</key>
    <string>bar.foo.WikiVirtualBox</string>
<key>ProgramArguments</key>
<array>
<string>/usr/bin/VBoxHeadless</string>
<string>-s</string>
<string>wiki</string>
</array>
<key>RunAtLoad</key>
<true></true>
<key>UserName</key>
<string>root</string>
<key>WorkingDirectory</key>
<string>/var/root</string>
<key>StandardErrorPath</key>
<string>/var/log/bar.foo.WikiVirtualBox.stderr.log</string>
<key>StandardOutPath</key>
<string>/var/log/bar.foo.WikiVirtualBox.stdout.log</string>
</dict>
</plist>

and told launchd to start it:

sudo launchctl load -w /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist

.

The Logfile

But the VM doesn't start. A Look at

tail -f /var/log/system.log

shows:

sudo[1909]: administrator : TTY=ttys000 ; PWD=/Users/administrator ; USER=root ; COMMAND=/bin/launchctl load -w /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist
VBoxSVC[1914]: 3891612: (connectAndCheck) Untrusted apps are not allowed to connect to or launch Window Server before login.
VBoxSVC[1914]: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
com.apple.launchd[1] (bar.foo.WikiVirtualBox[1910]): Exited with exit code: 1

When i log into the server via ssh (so no login window opened) i can run:

/usr/bin/VBoxHeadless -s wiki

and it works. So i don't understand the error above.
