Add the script below in the /etc/rc.d/rc.local.

#!/bin/sh
#
# /etc/rc.d/rc.local:  Local system initialization script.
#
# Put any local startup commands in here.  Also, if you have
# anything that needs to be run at shutdown time you can
# make an /etc/rc.d/rc.local_shutdown script and put those
# commands in there.

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

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

Create /etc/rc.d/rc.local_shutdown and add the script below.

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

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

chmod 755 /etc/rc.d/rc.local_shutdown

The Virtualbox need a group owner vboxusers. So create vboxusers group:

 groupadd -g 103 vboxusers

Add user to the group:

usermod -G packager, vboxusers luzar

groups luzar
