Script 1 to start a virtualbox (vbox_start_vm)
Starts and sleeps x number of seconds, but doesn't start it if it's already running!
#!/bin/bash
if [ -z $1 ] ; then
echo "SERVER Name is Missing... the number is 42."
echo "usage vbox_single_start "
exit 1
fi
if /usr/bin/VBoxManage -q showvminfo $1 | grep -i running ; then
echo VM Guest $1 is already powered on!
exit 1
else
echo Starting $1
/usr/bin/VBoxManage startvm $1 --type vrdp
if [ $2 ] ; then
sleep $2
fi
fi
exit 0
Script 2 to stop a virtualbox (vbox_stop_vm)
This script tries to acpi-shutdown the system, and wait for 240 seconds before forcing it down if all fails.
#!/bin/bash
MAX_WAIT_TIME=300 # max seconds to wait before doing poweroff (force)
function wait_until_machine_shutdown_else_terminate {
if /usr/bin/VBoxManage -q list runningvms | grep -i $1 ; then
#echo "sleeping 10 seconds"
sleep 10
let MAX_WAIT_TIME=MAX_WAIT_TIME-10
if [ $MAX_WAIT_TIME -lt 0 ] ; then
echo "Had to force the power on the server... Sorry about that!"
/usr/bin/VBoxManage controlvm $1 poweroff
sleep 10
else
if [ $MAX_WAIT_TIME -lt 200 ] ; then
#try to do another acpipowerbutton
/usr/bin/VBoxManage controlvm $1 acpipowerbutton
fi
wait_until_machine_shutdown_else_terminate $1
fi
fi
}
#ensure that the server name is entered
if [ -z $1 ] ; then
echo "SERVER Name is Missing... the number is 42."
echo "usage vbox_stop_vm "
exit 1
fi
if /usr/bin/VBoxManage -q showvminfo $1 | grep -i running ; then
echo VM Guest $1 is powered on! Will send ACPI shutdown.
/usr/bin/VBoxManage controlvm $1 acpipowerbutton
# if parameter for sleep is provided, do here
if [ $2 ] ; then
sleep $2
fi
# wait until it's been shutdown!
wait_until_machine_shutdown_else_terminate $1
else
echo Server $1 is not running!
exit 1
fi
exit 0
Script 3 - the actual init.d script calling the other scripts (call it what you want on your system)
#! /bin/sh
# some errors with networking, so need to restart at end of init sequence
#NOT NEEDED BRIDGE WORKS?!?!?!?!

I needed to implement these functions, as I now have 1 Ubuntu server with Virtualbox on top running all 5 servers at home. I wanted to have a full-blown test environment to play around in without having more than 1 server.
The only problem so far is that the disk controller wasn't fast enough (Dell SAS 6/ir). To help this perform better I added an extra HD outside the SAS controller running the swap spaces and the pagefiles for the Windows servers. That made a huge difference, especially for the windows servers. If you are going to run your vm's on a mirrored raid, I won't recommend the SAS 6/ir if the virtual servers will be accessed by more than 20-25 users. It will feel a bit sluggish... Maybe not so much for the users, but if you do iostat as a admin, you will be in "shock" over the terrible write performance for the SAS 6/ir in mirror mode.
