Postby frank » 17. Jun 2009, 09:05

Please do not use this VirtualBox Beta release on production machines. A VirtualBox Beta release should be considered a bleeding-edge release meant for early evaluation and testing purposes.

You can download the binaries here.

Please do NOT open bug reports at but use this forum to report any problems with the Beta.

Version 3.0 will be a major update. The following major new features were added:
  • Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only)
  • Windows guests: ability to use Direct3D 8/9 applications / games (experimental)
  • Support for OpenGL 2.0 for Windows, Linux and Solaris guests
In addition, the following items were ?xed and/or added:
  • Virtual mouse device: eliminated micro-movements of the virtual mouse which were confusing some applications (bug #3782)
  • Solaris hosts: allow suspend/resume on the host when a VM is running (bug #3826)
  • Solaris hosts: tighten the restriction for contiguous physical memory under certain conditions
  • VMM: ?xed occassional guru meditation when loading a saved state (VT-x only)
  • VMM: eliminated IO-APIC overhead with 32 bits guests (VT-x only, some Intel CPUs don’t support this feature (most do); bug #638)
  • VMM: ?xed 64 bits CentOS guest hangs during early boot (AMD-V only; bug #3927)
  • VMM: performance improvements for certain PAE guests (e.g. Linux 2.6.29+ kernels)
  • GUI: added mini toolbar for fullscreen and seamless mode (Thanks to Huihong Luo)
  • GUI: redesigned settings dialogs
  • GUI: allow to create/remove one host-only network adapters
  • GUI: display estimated time for long running operations (e.g. OVF import/export)
  • GUI: Fixed rare hangs when open the OVF import/export wizards (bug #4157)
  • VRDP: support Windows 7 RDP client
  • Networking: ?xed another problem with TX checksum of?oading with Linux kernels up to version 2.6.18
  • VHD: properly write empty sectors when cloning of VHD images (bug #4080)
  • VHD: ?xed crash when discarding snapshots of a VHD image
  • VBoxManage: ?xed incorrect partition table processing when creating VMDK ?les giving raw partition access (bug #3510)
  • OVF: several OVF 1.0 compatibility ?xes
  • Shared Folders: sometimes a ?le was created using the wrong permissions (2.2.0 regression; bug #3785)
  • Shared Folders: allow to change ?le attributes from Linux guests and use the correct ?le mode when creating ?les
  • Shared Folders: ?xed incorrect ?le timestamps, when using Windows guest on a Linux host (bug #3404)
  • Linux guests: new daemon vboxadd-service to handle time syncronization and guest property lookup
  • Linux guests: implemented guest properties (OS info, logged in users, basic network information)
  • Windows host installer: VirtualBox Python API can now be installed automatically (requires Python and Win32 Extensions installed)
  • USB: Support for high-speed isochronous endpoints has been added. In addition, read-ahead buffering is performed for input endpoints (currently Linux hosts only). This should allow additional devices to work, notably webcams
  • NAT: allow to con?gure socket and internal parameters
  • Registration dialog uses Sun Online accounts now
