VirtualBox - a program to run on the same computer multiple virtual operating systems. It is a handy and

functional tool for virtualization, calculated kahk for corporate and home-users. The program supports many

different guests on the family Windows (NT/2000/XP/2003/Vista/7), as well as DOS, Linux and OpenBSD. As in

other similar applications, there exists the possibility to start and stop the guest operating system,

configuration of computer resources, exchange of data between primary and guest operating system, taking

screenshots of the virtual system and much more.

Key features of the program:
"Support for USB 2.0, when the device host machines are available for guest OS
"Built-in RDP-server and client support for USB-devices over RDP protocol
'Experimental support for images drives VMDK / VMware
"Support for iSCSI
"Virtualization support audio
"Support for various types of networking (NAT, Host Networking via Bridged, Internal)
"Support for the tree saved state the virtual machine (snapshots), which may be made from any state rollback

guest
"Support for Shared Folders to easily share files between the host and guest systems
"Cross-platform
"Modularity
And much more ...

E1000: disconnect cable was not properly handled if the NIC was not yet initialized by the guest
OVF: export performance optimization
OVF: upgraded OS type definitions to CIM 2.25.0 so that Windows 7 and other OSes are now tagged correctly on

export
