VirtualBox 3.2.0 Beta 1
VirtualBox è uno dei più popolari software di virtualizzazione.


  • 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
In addition, the following items were fixed and/or added:
  • VMM: fixed crash with the OpenSUSE 11.3 milestone kernel during early boot (software virtualization only)
  • VMM: fixed OS/2 guest crash with nested paging enabled
  • VMM: fixed Windows 2000 guest crash when configured with a large amount of RAM (bug 5800)
  • VMM: fixed massive display performance loss (AMD-V with nested paging only)
  • Linux/Solaris guests: PAM module for automatic logons added
  • GUI: guess the OS type from the OS name when creating a new VM
  • GUI: added VM setting for passing the time in UTC instead of passing the local host time to the guest (bug 1310)
  • GUI: fixed seamless mode on secondary monitors (bugs 1322 and 1669)
  • GUI: added --seamless and --fullscreen command line switches (bug 4220)
  • Settings: be more robust when saving the XML settings files
  • Mac OS X: rewrite of the CoreAudio driver and added support for audio input (bug 5869)
  • Mac OS X: external VRDP authentication module support (bug 3106)
  • Mac OS X: Moved the realtime dock preview settings to the VM settings (no global option anymore). Use the dock menu to configure it.
  • Mac OS X: added the VM menu to the dock menu
  • VBoxManage: iSCSI disks do not support adding a comment (bug 4460)
  • 3D support: fixed corrupted surface rendering (bug 5695)
  • 3D support: fixed VM crashes when using ARB_IMAGING (bug 6014)
  • 3D support: fixed assertion when guest applications uses several windows with single OpenGL context (bug 4598)
  • 3D support: added GL_ARB_pixel_buffer_object support
  • 3D support: added OpenGL 2.1 support
  • 3D support: fixed Final frame of Compiz animation not updated to the screen (Mac OS X only) (bug 4653)
  • Added support for virtual high precision event timer (HPET)
  • LsiLogic: Fixed detection of hard disks attached to port 0 when using the drivers from LSI
  • NAT: fixed ICMP latency (non-Windows hosts only; bug 6427)
  • Keyboard/Mouse emulation: fixed handling of simultaneous mouse/keyboard events under certain circumstances (bug 5375)
  • Shared folders: fixed issue with copying read-only files (Linux guests only; bug 4890)
  • OVF: fixed mapping between two IDE channels in OVF and the one IDE controller in VirtualBox
