    If this is the case then I suspect you are not running the current version of VirtualBox (4.2.16)? You haven't stated the version anywhere here.

    Re: VM VirtualBox w/Ubuntu 13.04 - Running Super Slow

    Having very slow perform when running Ubuntu 12.10 and 13.04 in virtualbox? It’s because Ubuntu can’t use graphics card for acceleration, ubuntu uses CPU for rendering graphics trough LLVMpipe. It makes running ubuntu in virualbox really slow. http://namhuy.net/951/how-to-fix-slo...irtualbox.html

    To check if your Ubuntu 12.10 or 13.04 guest is using 3D acceleration
    Code:
    /usr/lib/nux/unity_support_test -p
    You should see something like this
    Code:
    Not software rendered: no
    Not blacklisted: yes
    GLX fbconfig: yes
    GLX texture from pixmap: yes
    GL npot or rect textures: yes
    GL vertex program: yes
    GL fragment program: yes
    GL vertex buffer object: yes
    GL framebuffer object: yes
    GL version is 1.4+: yes
    Unity 3D supported: no
    If you see “Not software rendered” and “Unity 3D supported” both say no. This means Unity is using slow LLVMpipe.

    To enable 3D supported, fist you will need to update linux-headers
    Code:
    uname -r
    sudo apt-get install linux-headers-$(uname -r)
    sudo apt-get autoremove
    sudo apt-get install build-essential
    Now insert vitualbox guest iso from devices and to install manually
    Code:
    cd /media
    ls
    cd username
    ls
    cd VBOX*
    ls
    sudo ./VBoxLinuxAdditions.run
    Insert vboxvideo to /etc/modules
    Code:
    sudo nano /etc/modules
    Add “vboxvideo” at the end of the file
    Code:
    loop
    lp
    vboxvideo
    Reboot the machine
    Code:
    sudo reboot
