Virtualbox on OS6 NAS

I've just installed VirtualBox on my ReadyNAS 516 with VT-x support. This was a clean fresh out of the box NAS without any other apps or programs installed.

Here are the instructions I used, I am more of a weekend warrior when it comes to linux so I reserve the right to make errors below but it worked perfectly for me.

    # Installing VirtualBox (4.3.12-93733) on ReadyNAS OS6 (6.1.8)
    # feel free and make changes to this as required

    # More virtualbox dependancies

    # Get the latest from virtualbox.org (debian build) and run the command below from the path containing the virtualbox .deb file
    dpkg -i virtualbox-4.3_4.3.12-93733~Debian~wheezy_amd64.deb

    # Run this to fix missing dependancies if the line above flags any (I needed to)
    apt-get -f install

    ## OPTIONAL settings for VirtualBox (4.3.12-93733)
    ## OPTIONAL ## Due to space/permission limitations of /root/VirtualBox VMs/ this will setup a symbolic link to a hidden shared I created called VirtualBox
    cd ~/
    rm -rf VirtualBox\ VMs
    ln -s /data/VirtualBox ~/VirtualBox\ VMs

    ## OPTIONAL ## Export existing VM (This needs to be done on the current host of the VM)
    vboxmanage export "VM_NAME" -o VM_NAME.ova

    ## OPTIONAL ## Importing VM (first line is just a dry run with listing options you can change during import)
    vboxmanage import VM_NAME.ova --dry-run -n
    vboxmanage import VM_NAME.ova --options

    ## OPTIONAL ## Don't forget to update the guest additions if you were running an older version

    ## Start VM ##
