Running virtualbox on Slackware.
		--------------------------------


	Users and groups.

The virtualbox-host Slackware package uses the following uid and gid:

vboxhost  215	The user account under which system wide virtal machines are
		running. This actually acts as a normal user and the group
		for this user is vboxusers.
vboxusers 215	Users added to this group are allowed to run private virtual
		machines.




	Init scripts and configuration.

The init script is installed as /etc/rc.d/rc.virtualbox and that script does
loading and unloading kernel modules, start and stop machines that should
autorun in headless mode, and start or stop the vboxwebsrv daemon if this
package was compiled with gsoap support. If you will not autorun headless
virtual machines, just add "/etc/rc.d/rc.virtualbox start" to rc.local.
If your main purpose is to run "headless", then it's better to add the
init script to /etc/rc.d/rc.M and /etc/rc.d/rc.6.

In /etc/rc.d/rc.M around line 327:

# Start the sendmail daemon:
if [ -x /etc/rc.d/rc.sendmail ]; then
  . /etc/rc.d/rc.sendmail start
fi

# Start virtualbox
if [ -x /etc/rc.d/rc.virtualbox ]; then
  /etc/rc.d/rc.virtualbox start
fi

# Load ALSA (sound) defaults:
if [ -x /etc/rc.d/rc.alsa ]; then
  . /etc/rc.d/rc.alsa
fi


In /etc/rc.d/rc.6 around line 133:

# Shut down YP services:
if [ -x /etc/rc.d/rc.yp ]; then
  if grep -wq stop /etc/rc.d/rc.yp ; then
    /etc/rc.d/rc.yp stop
  fi
fi

# Stop virtual machines
if [ -x /etc/rc.d/rc.virtualbox ]; then
  /etc/rc.d/rc.virtualbox stop
fi

# Bring down the networking system, but first make sure that this
# isn't a diskless client with the / partition mounted via NFS:
if ! /bin/mount | /bin/grep -q 'on / type nfs' ; then
  if [ -x /etc/rc.d/rc.inet1 ]; then
    . /etc/rc.d/rc.inet1 stop
  fi
fi




	Autorun machines.

To autorun headless machines add these to /etc/vbox/autorun.cfg like this:

# Account to use.
VBOXHOST="vboxhost"
i=0

# Machine definitions, add them in the order to start. They will be stopped
# in the reverse order. Remmember to add a line to increase $i after each
# machine.

VBOX_NAME[$i]="MBSE Gateway"                            # name of the machine
VBOX_UUID[$i]="02117c0e-9fe0-492a-8ff2-b4ffe0f94960"    # uuid of the machine
VBOX_AUTO[$i]="false"                                   # true to start
VBOX_STOP[$i]="acpipowerbutton"                         # or acpibutton
VBOX_PORT[$i]=5000                                      # RDP port
i=$(($i+1))                                             # next

VBOX_NAME[$i]="MBSE Web"                                # name of the machine
VBOX_UUID[$i]="6e3611d9-0a38-4e75-8ca7-8db67d976326"    # uuid of the machine
VBOX_AUTO[$i]="true"                                    # true to start
VBOX_STOP[$i]="acpipowerbutton"                         # or savestate
VBOX_PORT[$i]=5001                                      # RDP port
i=$(($i+1))

To stop a machine use savestate or acpipowerbutton. The savestate option is
fast, but users logged in such machine are not warned but experience a freeze.
Choosing the acpipowerbutton does a normal shutdown but takes a lot longer.
This is IMHO the best choice for virtual servers.
