VirtualBox 4.3 Beta 2 released

Postby Frank Mehnert » 9. Sep 2013, 22:53

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 our VirtualBox Beta Feedback forum to report any problems with the Beta. Please concentrate on reporting regressions since VirtualBox 4.2.18.

VirtualBox 4.3 will be a new major release. Here is an incomplete list of chances since VirtualBox 4.3 Beta 1:
  • VMM: fixed several regressions; fixed accessing certain MSRs (Intel and AMD)
  • VMM: fixed 64-bit guests on 32-bit hosts including fixes for host crashes under certain conditions (see 11979).
  • VMM: fixed panics on Mac OS X, see here
  • VMM: allow to use VT-x in SMX mode
  • GUI: more settings validation fixes
  • GUI: medium enumeration overhaul to speed up opening the settings dialog
  • GUI: fixed crashes under certain conditions on X11 hosts
  • Main: extension pack framework can now support loading HGCM modules, contributed by Jeff Westphal
  • Settings: the exclusive HW virtualization setting is now global, not per-VM as before
  • NAT: fixed port-forwarding
  • NAT: binding IPv4 connectivity to specified interface (global extradata "NAT/<network-name>/SourceIp4" ipv4)
  • NAT: DHCP reports list of DNS servers (w/o loopback mapping)
  • USB: detect USB2 devices on USB3 ports (Windows hosts only)
  • OVF: fixed import regression with double OHCI controller
  • 3D: fixed 3D-related crashes and Windows 8.1 rendering issues on OSX hosts
  • 3D: fixed Ubuntu 13.04 3D desktop rendering issues
  • Solaris hosts: dropped 32-bit support
  • Windows Additions: several autoresize and seamless fixes
  • Windows Additions: updated Wine sources
  • Windows Additions: fixed NT4 regression, see here

Thank you for testing!
