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.
