Additionally, the GUI now allows users to modify some settings while a VM is running previously a VM needed to be shut down first. The major update is the first VM VirtualBox release to officially support Microsoft's upcoming Windows 8 operating system, Mac OS X 10.8 Lion and version 6.3 of Oracle Linux from the end of June, and it brings with it several new features aimed at advanced users.Ī new "expert mode" has been added to wizards to make them quicker for experienced users and, for users with a large number of virtual machines (VMs), these can now be organised into categories and groups to make them easier to find. Oracle and the VirtualBox developers have released version 4.2 of their open source desktop virtualisation application with network and management improvements, as well as support for new platforms.
