Virtualbox 4.3 Released, Install or Upgrade in Ubuntu & Linux Mint

Last updated: December 9, 2013

Oracle VM Virtualbox 4.3.0 has been released. In this tutorial I’ll show you what’s new and how to install / upgrade Virtualbox 4.3 in Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04, Linux Mint and Elementary OS.

What’s New in Virtualbox 4.3.0:

This version is a major update. The following major new features were added:

  • VMM: major rewrite of the VT-x code and the AMD-V code including many bug fixes and performance improvements
  • VMM: introduced a lightweight instruction interpreter for situations not handled by hardware virtualization
  • GUI: extended messaging mechanism (new non-modal popup overlays used to show non-critical warnings and provide user with additional information)
  • GUI: keyboard shortcuts management (input page of global preferences extended with possibility to edit general keyboard shortcuts for VirtualBox Manager and Virtual Machine)
  • GUI: video capturing support (bug #4766)
  • Added USB touch device emulation
  • Added experimental support for webcam passthrough complementing USB passthrough (see the manual for more information)
  • Added SCSI CD-ROM emulation, including boot support
  • VRDP: support for IPv6
  • Guest Control: guest sessions now are running in dedicated, impersonated session processes (needs at least Guest Additions 4.3 installed)
  • Guest Control: implemented IGuestFile support
  • NAT: experimental virtual router mode: several VMs are attached to the same internal network and share one
  • NAT service (see the manual for more information)
  • In addition, the following items were fixed and/or added:

  • VMM: significantly improved performance of NetWare 5.x/6.x guests on host systems without nested paging support
  • VMM: fixed losing host NMIs while in VT-x guest-context
  • VMM: changed order of actions in emulated task switch (bug #10532)
  • VMM: allow to activate VT-x while in SMX mode and provide more information if that is not possible
  • GUI: update check uses https
  • GUI: numerous minor internal cleanups and bug fixes
  • GUI: HID LEDs synchronization when switching between guest window(s) and host (Mac OS X hosts only)
  • GUI, VBoxManage: when unregistering a VM, also unregister the hard disk images which are used exclusively (bug #10311)
  • GUI: use the number of physical presented processor cores instead of the number of logical processor cores to check if the users assigned too many virtual CPUs to the guest
  • Snapshots: made live snapshots work again (bug #9255)
  • Teleportation: made it work again (bug #9455)
  • Storage: implemented AHA-154x compatibility mode in the emulated BusLogic SCSI HBA
  • Storage: significantly improved performance of large ATAPI PIO transfers (BeOS, Minix 3 guests affected)
  • Storage: added floppy formatting emulation (NB: cannot be used to change existing media geometry)
  • Settings: global and per-VM default frontend configuration, useful to select the use of alternative VM frontends
  • Settings: limit depth of snapshot tree to 250 levels, as more will lead to decreased performance and may trigger crashes
  • Settings: the per-VM hwvirtextexcl setting has been replaced by a global hwvirtexclusive property
  • Main: new event queue implementation which does not use the host’s native event queue for processing VirtualBox events anymore
  • Main: eliminate the use of SysV semaphores on all host OSes other than Windows, namely Linux, Solaris and Mac OS X, with the consequence that no system reconfiguration is needed to run more than approximately 100 VMs
  • Main: use the XDG standard configuration folder instead of .VirtualBox on systems where it is appropriate (bug #5099)
  • Main: extension pack framework can now support loading HGCM modules, contributed by Jeff Westphal
  • VBoxManage: list more information about hard disk/DVD/floppy media, and support the –long option to show really all available details
  • VBoxManage: added support for optional command line parameters for the automatic Guest Additions update
  • VBoxManage: added support for listing active guest sessions, guest processes and/or guest files via guestcontrol list
  • VBoxManage: added support for closing active guest sessions via guestcontrol session close –session-id | –session-name | –all
  • VBoxManage: added support for terminating active guest processes via guestcontrol process kill|close|terminate –session-id | –session-name … or guestcontrol [p[s]]kill –session-id | –session-name …
  • VBoxManage: added support for watching guest sessions via guestcontrol watch
  • VBoxManage: added modifyvm –triplefaultreset to make the VM reset on triple fault instead of triggering a Guru Meditation (see the manual for more information)
  • 3D support: several fixes
  • 3D support: several fixes for Mac OS X hosts
  • OVF: several fixes
  • Extpack Installer: make it work if the file is located in a folder with special characters
  • Keyboard: fix for reporting key sequences like Ctrl+Alt+Del for the USB keyboard emulation
  • Shared Clipboard/X11: support for BMP-format images, contributed by François Revol
  • Mac OS X hosts: limited support for Mac OS X 10.9 (Mavericks)
  • Mac OS X hosts: use a launchd script instead of the deprecated StartupItem mechanism (bug #8940)
  • Windows hosts: don’t cause massive DPC latency (only on certain hosts; still needs improving; bug #6242)
  • Windows hosts: consider symlinks when retrieving volume information (bug #11962)
  • Windows hosts: fixed an issue with USB2 devices being inaccessible when plugged into USB 3.0 ports
  • Windows Additions: fixed misbehavior with guest display power management (WDDM driver only; bug #11170)
  • Windows Additions: fixed memory leak caused by WTSQuerySessionInformation() on Windows 2000 guests (bug #12072)
  • Windows Additions: ability to track guest user idle times through the newly introduced event IGuestUserStateChangedEvent
  • Linux Additions: fixed udev detection in the init script with Linux 3.x kernels

  • Install or Upgrade to Virtualbox 4.3:

    DEBs for Ubuntu Linux and its derivatives is available at this page. I’ve installed the 64-bit deb for Raring on Ubuntu Saucy, and it works great!

    If you’re familiar with command line, you can also run below commands one by one in terminal (Ctrl+Alt+T) to install virtualbox 4.3 from its official repository:

    sudo sh -c 'echo "deb $(lsb_release -sc) contrib" >> /etc/apt/sources.list'
    wget -q -O- | sudo apt-key add -
    sudo apt-get update
    sudo apt-get install virtualbox-4.3

    1. Saucy release not found when I added and then updated..

      sudo sh -c ‘echo “deb $(lsb_release -sc) contrib” >> /etc/apt/sources.list’

      • At the moment, Virtualbox repository is not available for Ubuntu 13.10 Saucy. (As I said in post) Use the Deb for Ubuntu 13.04, it works great for me!

    2. Doesn’t work in ubuntu 13.10….

      • Post updated!

        Oracle now provides the same DEBs installer for Raring and Saucy in virtualbox official download page, which means Raring repository for virtualbox also works in Saucy.

    3. I made it to the final install command, and now I get:
      E: Unable to locate package virtualbox-4.3
      E: Couldn’t find any package by regex ‘virtualbox-4.3’

      I’m running 64-bit “Olivia”

      • Check out if the repository was added properly by:

        1. open up file browser and navigate to Computer (or System)-> etc -> apt. All source and repositories are added in sources.list file (or files under sources.list.d/ folder).

        2. This article was teaching to add VBox repository to sources.list. So open it up, and check out if there’s a line said:

        deb raring contrib

        Olivia is based on Ubuntu raring. For other releases, you may change raring to other Ubuntu release code name

        3. If the repository source is really here, you should be able to install virtualbox-4.3 after checking for updates:

        sudo apt-get update

        If previous lines does not help, please download the DEBs (for raring) from the second link in the article.

    4. It worked well and directly for Ubuntu 13.10 and VirtualBox 4.3.6, upgraded from 4.2.x
      Thanks a lot

    5. this was happyfull for me

    6. Wow, this really worked. Thank you very much for your help.

    7. Error encountered:

      W: Failed to fetch “” 404 Not found

      W: Failed to fetch “” 404 Not found

      • Seems that you’re using eOS Luna which is based on Ubuntu 12.04. You have to edit the /etc/apt/sources.list manually and change the line:

        deb luna contrib


        deb precise contrib

        To do so, run below command in terminal to open the file with default text editor:

        sudo scratch-text-editor /etc/apt/sources.list

        When the file opens, edit the line and save it.

        Finally, re-run below commands to refresh system cache and install vbox-4.3:

        sudo apt-get update
        sudo apt-get install virtualbox-4.3
