The SUN company released an updated version of VirtualBox. Overall, the upgrade is aimed at correcting a number of various bugs.
VirtualBox - a program for creating virtual machines. By allocating resources it creates a separate virtual computer system from their own resources, and, most importantly, with its own operating system. For example, the computer operating system is Windows in the two accounts you can create a virtual system, under which use certain resources and install Linux. Or, rather, on computers running Linux install Windows. The program supports the installation of the operating system from a disk or file-image. Everything is very simple and will not cause serious difficulties even for novice users. It remains to add that the program is completely free and distributed on the basis of open source.
The main operating system VirtualBox supports Windows, Linux, Mac OS and Solaris. In the role of a virtual system could be virtually all popular operating systems.
