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

- 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
- 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)
- CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only) (see the manual for more information)

Interessante documento rilasciato da Citrix, CTX123655, che spiega tutti i passi per creare una Virtual Machine su XenServer 5.5, Windows o Linux, e la corretta procedura per fare P2V da server fisici.
Ecco il link.
Dopo indiscrezioni nella community di virtualbox.org sulla nuova release, ecco che SUN rilascia la nuova major update di VirtualBox 3.1.
