VirtualBox 3.2.0 (released 2010-05-18)
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 Server 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 preparation feature; see the manual for more information)
- OVF: enhanced OVF support with custom namespace to preserve settings that are not part of the base OVF standard
In addition, the following items were fixed and/or added:
- VMM: fixed Windows 2000 guest crash when configured with a large amount of RAM (bug #5800)
- Linux/Solaris guests: PAM module for automatic logons added
