Oracle has released the third beta release of version 4.3 of VirtualBox. VirtualBox can be used to install other operating systems in a virtual environment on a computer. In this way it is possible to use different operating systems on the same hardware side by side and at the same time. VirtualBox is available for Windows XP and above, OS X, Linux, and Solaris, and is capable of many guest operating systems to turn.

In version 4.3 of VirtualBox, among other things, the complete virtualization code has been rewritten, which has solved several problems and also shows several performance improvements. In addition, there is video capture and support for ipv6, and several virtual machines running on the same computer can now communicate with each other via the internal network. The main changes made further in beta 3 can be found below.

Here is an incomplete list of chances since VirtualBox 4.3 Beta 2:

  • VMM: implemented thread-context hooks for Linux and Solaris hosts
  • VMM: several fixes
  • GUI: added NAT networks to the global settings page
  • GUI: made NAT network a separate network attachment type
