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. (they are being built and uploaded as of 20:53 CET)

This version is a major update. The following major new features were added:

  • OVF (Open Virtualization Format) appliance import and export
  • Host-only networking mode
  • Hypervisor optimizations with significant performance gains for high context switching rates
  • VT-x/AMD-V are enabled by default for newly created virtual machines
  • USB (OHCI & EHCI) is enabled by default for newly created virtual machines (Qt GUI only)
  • Experimental USB support for OpenSolaris hosts
  • Shared folders for Solaris and OpenSolaris guests
  • OpenGL 3d acceleration for Linux guests
  • Experimental support for OS X 10.6 (Snow Leopard) hosts running both the 64-bit and the 32-bit kernel

In addition, the following items were fixed and/or added:

  • VMM: FreeBSD guest related fix for V86 flags (bug #2342)
  • VMM: Fixed guru meditation when booting an AsteriskNow Linux VM (bug #2342)
  • VMM: Fixed PGMPOOLKIND_FREE guru meditation (bugs #3356, #3431)
  • VMM: Fixed Windows XP boot hang (guest PAE + nested paging only)
  • VMM: Allow mixing of VT-x/AMD-V and software virtualization
  • VMM: fixed extremely slow safe mode booting in e.g. Windows 2008 (VT-x/AMD-V only)
  • VMM: significant speedup of certain Grub boot loaders (e.g. Solaris) (VT-x/AMD-V only)
  • VMM: real-mode IOPL fix for DOS guests (VT-x only)
  • VMM: fixed VT-x detection with certain BIOSes that enable VT-x, but don't set the lock bit in MSR_IA32_FEATURE_CONTROL
  • NAT: Truncated downloads with NAT (ftp) (bug #3257)
  • NAT: Blocked UDP packets cause crash (bug #3426)
  • USB: further reduced host CPU utilization for OHCI and EHCI; the "VBoxInternal/Devices/usb-ohci/0/Config/FrameRate" CFG key is no longer necessary and no longer supported
  • VRDP: fixed hangs when VRDP server is enabled or disabled in runtime
  • X11 guests: show the guest mouse pointer at the right position if the virtual desktop is larger than the guest resolution (bug #2306)
  • Solaris guests: added xpg4/xcu4 dependency to the guest additions installer (bug #3524)
  • Linux hosts: do proper reference counting to prevent unloading the vboxnetflt module as long as this code is in use
  • Linux installers: fixes for Slackware, Arch Linux and Linux from Scratch systems
  • Windows installers: Combined installer executable which contains both (32- and 64-bit) architectures
  • VBoxManage: less cryptic command-line error messages
  • VBoxManage: 'list vm' commands now default to compact format
  • Hard disks: improved immutable disk support to auto-reset diff file at VM startup
  • GUI: enable the audio adapter by default for new VMs
  • GUI: warn if VT-x/AMD-V is not operational when starting a 64 bits guest
  • GUI: deactivate 64 bits guest support when the host CPU does not support VT-x/AMD-V
  • GUI: removed floppy icon from the status bar
  • GUI: show build revision in about dialog
  • GUI: fixed sticky status bar text
  • GUI/Mac OS X: fixed disabled close button
  • GUI: improved error dialogs
  • 3D support: added opengl select/feedback support (bug #2920)
  • 3D support: close opengl subsystem for terminated guest applications (bug #3243)
  • 3D support: fixed VM hangs when starting guests with 3D acceleration enabled (bug #3437)
  • PXE: fixed boot hangs when hardware virtualization is used (bug #2536)
