What a name! Oracle VM VirtualBox?

Major version update!!!

VirtualBox Version 3.2.0 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 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)
  • 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 (see the manual for more information)
  • 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
  • Guest Additions: added support for executing guest applications from the host system
  • OVF: enhanced OVF support with custom namespace to preserve settings that are not part of the base OVF standard
