I wanted to configure multiple VirtualBox VMs to startup automatically at boot
time and generally be a nice citizen to the FreeBSD way of starting up stuff.
Using that rc.d script (see attached) you can configure starting up multiple
VirtualBox VMs from /etc/rc.conf:
## VirtualBox VMs
vboxvm_enable="YES"
vboxvm_machines="vm1 vm2"
## VM1
vboxvm_vm1_enable="YES"
vboxvm_vm1_name="vm1"
vboxvm_vm1_user="vbox_vm1"
vboxvm_vm1_log="vboxvm.log"
vboxvm_vm1_vncport="5901"
vboxvm_vm1_vncpassword="secret1"
## VM2
vboxvm_vm2_enable="YES"
vboxvm_vm2_name="vm2"
vboxvm_vm2_user="vbox_vm2"
vboxvm_vm2_log="vboxvm.log"
vboxvm_vm2_vncport="5902"
vboxvm_vm2_vncpassword="secret2"
==
The script must be put to
/usr/local/etc/rc.d/vboxvm
and understands three commands: start, stop and status.
You can use it on all VMs configured (and enabled)
$ /usr/local/etc/rc.d/vboxvm status
VBox machine 'vm1' is running.
VBox machine 'vm2' is running.
or on a specific VM
$ /usr/local/etc/rc.d/vboxvm stop vm1
==
The parameters:
vboxvm_<VM Name>_enable
=> mandatory : enable/disable the VM
vboxvm_<VM Name>_name
=> mandatory : VirtualBox name of the VM
vboxvm_<VM Name>_user
=> mandatory : the Unix user under which the VM will be run (using VBoxHeadless)
vboxvm_<VM Name>_log
=> optional : log file when VBoxHeadless runs the VM
vboxvm_<VM Name>_vncport
=> optional : when given, VBoxHeadless with active VNC server embedded
vboxvm_<VM Name>_vncpassword
=> optional : when VNC is active, a password
==
bugs/limits:
1) the restart/rcvar commands do now work
2) when the system shuts down, it doesnt wait for "stop" to finish graceful
shutdown of VMs
I'm new to writing rc.d on FreeBSD, so if someone knows how to fix those, I'd
be interested.

credits: the script skeleton was shamelessly stolen from
/usr/local/etc/rc.d/apache22 ;)
