VirtualBox init script for no root user

[virtual-lab]

Hi there,
I'm working to make guest OS run as no privileged user.
I've found a script made by an Italian guy that should start the guest instance during boot. Unfortunately the script was made for Debian and as I'm not confident with bash, I'm having some difficulties in making it work under RedHat 5.3

launched as root

vbox-ithaca start
vbox-ithaca: line 116: log_daemon_msg: command not found
sudo: VBoxManage startvm ithaca --type vrdp: command not found
vbox-ithaca: line 119: log_end_msg: command not found

these errors to me basically say that those commands aren't in PATH, but I couldn't find them anywhere

First, the VirtualBoxManage command is installed when you install the VirtualBox-OSE package. If that command is not available, you need to install that package.

Second, replace the log-daemon-msg command everywhere it occurs in the script by a simple echo.

Third, the script, as written, assumes that you have an image file, called "ithaca" available and debugged.

Fourth, good luck.
