Oracle releases VirtualBox 3.2

May 20th, 2010 1 comment

With the Sun now set, Oracle has released VirtualBox 3.2 finally 🙂 In particular some lovely optimisations for the newer Intel Core i5/i7 processors, Large  Page support (which helps significantly on Windows x64 and Linux) as well as a very welcome optimisation on the networking in VirtualBox as well as multi-monitor support for Windows Guests. Whats more RDP sessions are now accelerated (VRDP).

Amongst the changes from the changelog:

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

  • Following the acquisition of Sun Microsystems by Oracle Corporation, the product is now called Oracle VM VirtualBox and all references were changed without impacting compatibility
  • Experimental support for Mac OS X guests (see the manual for more information)
  • Memory ballooning to dynamically in- or decrease the amount of RAM used by a VM (64-bit hosts only) (see the manual for more information)
  • Page Fusion automatically de-duplicates RAM when running similar VMs thereby increasing capacity. Currently supported for Windows guests on 64-bit hosts (see the manual for more information)
  • CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only) (see the manual for more information)
  • New Hypervisor features: with both VT-x/AMD-V on 64-bit hosts, using large pages can improve performance (see the manual for more information); also, on VT-x, unrestricted guest execution is now supported (if nested paging is enabled with VT-x, real mode and protected mode without paging code runs faster, which mainly speeds up guest OS booting)
  • Support for deleting snapshots while the VM is running
  • Support for multi-monitor guest setups in the GUI for Windows guests (see the manual for more information)
  • USB tablet/keyboard emulation for improved user experience if no Guest Additions are available (see the manual for more information).
  • LsiLogic SAS controller emulation (see the manual for more information)
  • RDP video acceleration (see the manual for more information)
  • NAT engine configuration via API and VBoxManage
  • Use of host I/O cache is now configurable (see the manual for more information)
  • Guest Additions: added support for executing guest applications from the host system (replaces the automatic system presimparation feature; see the manual for more information)

Download from VirtualBox or get the Windows build. I’m really hoping the good Oracle keeps VirtualBox open, this is one kickass bit of kit.

Sun releases VirtualBox 2.0 just couple of days after 1.6.6!

September 7th, 2008 1 comment

One of the hottest Virtualisation applications going around the internets these days is Sun’s recently aquired VirtualBox software suite. The bright folks at Sun have just announced version 2.0 release which is a couple of days after the 1.6.6 maintenance release.

Being a fan of VirtualBox from around the 1.3.x days when it was owned by Innotek and seeing it mature the way it has, its been quite impressive – if not for the wide platform compatibility and the fact that its a ‘free’ product for personal use that’s competitive with commercial offerings such as VMWare – which has been my fulltime VM product (loving VMWare 6.5 btw!).

VirtualBox 2.0 brings some uber goodness to the mix (from the changelog):

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

    • 64 bits guest support (64 bits host only)
    • New native Leopard user interface on Mac OS X hosts
    • The GUI was converted from Qt3 to Qt4 with many visual improvements
    • New-version notifier
    • Guest property information interface
    • Host Interface Networking on Mac OS X hosts
    • New Host Interface Networking on Solaris hosts
    • Support for Nested Paging on modern AMD CPUs (major performance gain)
    • Framework for collecting performance and resource usage data (metrics)
    • Added SATA asynchronous IO (NCQ: Native Command Queuing) when accessing raw disks/partitions (major performance gain)
    • Clipboard integration for OS/2 Guests
    • Created separate SDK component featuring a new Python programming interface on Linux and Solaris hosts
    • Support for VHD disk images

    In addition, the following items were fixed and/or added:

    • VMM: VT-x fixes
    • AHCI/SATA: improved performance
    • GUI: keyboard fixes
    • Linux installer: properly uninstall the package even if unregistering the DKMS module fails
    • Linux additions: the guest screen resolution is properly restored
    • Network: added support for jumbo frames (> 1536 bytes)
    • Shared Folders: fixed guest crash with Windows Media Player 11
    • Mac OS X: Ctrl+Left mouse click doesn’t simulate a right mouse click in the guest anymore. Use Hostkey+Left for a right mouse click emulation. (bug #1766)

    Download your copy based on your Operating System:

    • VirtualBox 2.0.0 for Windows hosts x86 | AMD64 (only on Windows x64!)
    • VirtualBox 2.0.0 for Solaris and OpenSolaris hosts x86 | AMD64

    After installing 2.0, my 1.6.x images seamlessly moved to the 2.0 release with minimal fuss, just make sure you shutdown your VMs prior to upgrading to avoid hassles.

    Not to be forgotten is VMWare’s upcoming 6.5 release which is rolling full steam ahead!
