The second 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_BETA2/

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 changes have gone into this release.
  • Fixed snapshots of VMs with empty DVD attachments (3.1.0 Beta 1 regression)
  • Fixed snapshots of VMs with multiple attached disk drives (3.1.0 Beta 1 regression)
  • GUI: fixed a crash in the snapshots widget
  • VMM: guest SMP fixes in rare cases
  • VMM: fixed kernel panic with older Linux kernels, e.g. CentOS 5.3 (APIC; 3.0.12 + 3.1.0 Beta 1 regression)
  • 3D support: fixed Final frame of Compiz animation not updated to the screen (public ticket #4653, partly fixed, needs more work)
  • 2D/3D support, Windows: fix gl support test failure when VBox installation path contains spaces
  • 2D support: fix saved state restore failure when 2D is active and used by the guest (Playing a Video)
  • Creating a new VM sometimes failed (3.1.0 Beta 1 regression)
  • VBoxManage clonehd was broken if the same image was cloned concurrently
  • added VBoxManage usage information for Floppy/DVD images
  • Linux Additions: properly disable the seamless mode if the guest doesn't support it
  • Windows Additions: fixed high usage of VBoxService on Windows guests (3.1.0 Beta 1 regression)
  • Windows Additions: VBox Credential Provider fixes
  • Windows guests: fixed invisible mouse pointer when VM was restored from a saved state.
  • VirtIO: performance improvements
  • EFI: 32-bpp VGA driver was added.


Please refer to the VirtualBox 3.1 Beta 2 Changelog for a complete list of changes and enhancements. Also please read the known issues before installing this beta release.

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.

Must I re-install guest additions in all guests?

Posted by Weijun on November 23, 2009 at 01:53 PM CST #

In order to take advantage of new features (such as 2D acceleration for Windows guests) you will need to update your guest additions. I make it a practice to update guest additions each time I upgrade VirtualBox. I will make an exception to that rule if testing out a beta for a short period of time where I know I'm going to fall back to a previous version (like I did with Beta 1 and 3.0.12).
