VirtualBox 3.2 has just been released. Following the acquisition of Sun Microsystems by Oracle Corporation, "Sun Virtualbox" is now called "Oracle Virtualbox".
What's new in VirtualBox 3.2:
- 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)
And a lot more. A complete changelog can be found HERE.
