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.

Finally downloaded the latest 3.2.0 release of VirtualBox today and gave it ago!

From the forum post for this pre-release.
