VirtualBox 3.1 Beta 3 now available for download

The third beta release of VirtualBox 3.1 is now available for testing. You can download the binaries for all platforms at http://download.virtualbox.org/virtualbox/3.1.0_BETA3/

In addition to the new features introduced with Beta 1 (live migration, branched snapshots, new OpenSolaris USB support, 2D video acceleration, network changes while VM is running), the following are noteworthy changes since Beta 2.
  • VMM: fixes slow OpenSolaris booting (3.1.0 Beta 1 regression)
  • GUI: prevent hints being send for guest-initiated resizes
  • GUI: fix for saved mouse shape data which was incorrectly updated
  • Xml compatibility fixes with 3.0.x (CpuIdTree element)
  • Storage/VMDK: fix buffers for really huge VMDK files split into 2G pieces
  • EFI: added 64-bit firmware
  • 2D support: Saved state save/restore fixes
  • 2D support: fixed VM reset issues
  • Snapshots: suppresses the automatic resetting of immutable disk images on VM power-up if the machine has snapshots AND the current snapshot is an online snapshot, to avoid data corruption (the machine would otherwise be reset to a state which is equivalent of a poweroff of a running machine without a proper shutdown)
  • Guest Additions: fixed a rare guest crash with 2 or more guest CPUs
  • Windows Additions: improved file version lookup for guest OS information
  • Windows Additions: disabled some debug output
  • Linux Additions: fixed guests with Linux 2.4 kernels
  • Linux Additions: removed debugging symbols to save space (3.1.0 Beta 2 regression)
  • X11 Additions: fixed a bug which re-enabled the graphics (and dynamic resizing) capability when disabling seamless
  • X11 Additions: added more default resolutions for old guests
  • X11 Additions: workaround a bug in X.Org 1.3 which caused dynamic resizing to fail


Please refer to the VirtualBox 3.1 Beta 3 Changelog for a complete list of changes and enhancements.

Important Note: 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.
