How to start Virtual Machines automatically in VirtualBox

Create Config File for vboxcontrol service script

# mkdir /etc/virtualbox
# touch /etc/virtualbox/machines_enabled

The file “machines_enabled” located in “/etc/virtualbox” is where we list the names of the Guest VM’s that we want vboxcontrol to control.

To get a list of your current Guest VM names execute the following command and notice the name is in ” “:

$ VBoxManage list vms
"Windows XP" {5087b02a-5816-4c76-b302-c13175623023}
"Windows 7" {bcae660a-f627-46d6-8c95-9da97363eeea}
"Windows 2008" {3907173c-cc15-4820-a930-f0bb3c13cb7e}

Add Guest VM’s to “machines_enabled” include one VM name per line

# vi /etc/virtualbox/machines_enabled
Windows XP
Windows 7
Windows 2008

Add VirtualBox VM Service script

Create new init.d service script file and give execute permissions

# touch /etc/init.d/vboxcontrol
# chmod 755 /etc/init.d/vboxcontrol

Copy the following code into file “/etc/init.d/vboxcontrol”

#! /bin/sh
# vboxcontrol Startup script for VirtualBox Virtual Machines
#
# chkconfig: 345 98 02
# description: Manages VirtualBox VMs
# processname: vboxcontrol
#
# pidfile: /var/run/vboxcontrol/vboxcontrol.pid

Add vboxcontrol service to chkconfig registry

# chkconfig --add vboxcontrol

Tell chkconfig to create symlinks for runlevels and activate service vboxcontrol

# chkconfig vboxcontrol on

How to use vboxcontrol to control Guest VM’s running as a service

Start ALL VirtalMachines listed in machines_enable file:

# service vboxcontrol start

Stop ALL VirtualMachines currently running !!

# service vboxcontrol stop

View Status of Running VirtualMachines

# service vboxcontrol status

Start a Specific VirtualMachine Only !!

# service vboxcontrol start-vm

Stop a Specific VirtualMachine Only ( send acpipowerbutton signal )

# service vboxcontrol stop-vm

Send Power Kill signal to VirtualMachine (immediate power off)

# service vboxcontrol poweroff-vm
