Finalmente è uscita la major update del prodotto di virtualizzazione per desktop di Oracle, VirtualBox 3.2.

Nella nuova release troviamo nuove funzionalità e bugfix che affliggevano la precedente versione.

Da adesso VirtualBox prende ufficialmente  il nome di Oracle VM VirtualBox (come saprete SUN è stata acquisita da Oracle il 20 aprile 2009)

Vediamo cosa c’è di nuovo (changelog):

• Experimental support for Mac OS X guests
• Memory ballooning to dynamically in- or decrease the amount of RAM used by a VM (64-bit hosts only)
• Page Fusion automatically de-duplicates RAM when running similar VMs thereby increasing capacity. Currently supported for Windows guests on 64-bit hosts
• CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only)
• New Hypervisor features: with both VT-x/AMD-V on 64-bit hosts, using large pages can improve performance; 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
• USB tablet/keyboard emulation for improved user experience if no Guest Additions are available
• LsiLogic SAS controller emulation
• RDP video acceleration
• NAT engine configuration via API and VBoxManage
• Use of host I/O cache is now configurable
• Guest Additions: added support for executing guest applications from the host system (replaces the automatic system presimparation feature)
• OVF: enhanced OVF support with custom namespace to preserve settings that are not part of the base OVF standard
