Oracle releases VirtualBox 3.2.0 Beta 2

Oracle has released a new version of its VirtualBox virtualization platform, now officially called Oracle VM VirtualBox. Over the next few weeks we'll take a closer look at some of these new features in a lot more depth, but today we'll whet your appetite with the headline descriptions.

So, what's new in VirtualBox 3.2, check it out here:

•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
•USB tablet/keyboard emulation for improved user experience if no Guest Additions are available (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).
