VirtualBox a special program to create a memory PC virtual machines. Each virtual machine can contain an arbitrary set of virtual devices and a separate operating system. Scope of virtual machines is very wide - from performing the functions of software testing to create entire networks, which are easily scaled, load-balance and protect. VirtualBox is free, open-source software.
Extension Pack adds the following features:
The virtual USB 2.0 (EHCI) device; see the section called "USB settings".
VirtualBox Remote Desktop Protocol (VRDP) support; see the section called "Remote display (VRDP support)".
Intel PXE boot ROM with support for the E1000 network card.
Experimental support for PCI passthrough on Linux hosts; see the section called "PCI passthrough".
Run VirtualBox, go to the File menu "Properties" Plug-ins and add the downloaded file has the extension. Vbox-extpack
There are versions of VirtualBox, intended for installation on virtually all operating systems, including Windows, Linux, Macintosh and OpenSolaris. As a "guest" operating system can also be used in any operating system, including Windows (NT 4.0, 2000, XP, Server 2003, Vista, W7), DOS / Windows 3.x, Linux, and OpenBSD.
VirtualBox can run as a GUI-interface or through command line.
To expand the functions of the program, a special set of SDK.
Parameters of virtual machines are described in XML format and does not depend on the physical computer on which the system works. Therefore, the virtual computer format VirtalBox easily transferred from one PC to another.
When using the "guest" computer operating systems, Windows or Linux, you can use special tools which substantially facilitate switching between the physical and virtual computers.
For a quick exchange of files between the guest and the physical PC, you can create so-called "shared folders" (Shared folders), which are simultaneously accessible from both of these machines.
VirtualBox allows you to connect USB-devices to virtual machines, allowing virtual machines to work with them directly.
VirtualBox fully supports the remote access RDP (Remote Desktop Protocol). A virtual machine can act as RDP-server, allowing you to control it remotely.
This is a maintenance release. The following items were fixed and / or added:
VMM: properly handle NMIs on Linux hosts with X2APIC enabled
VMM: fixed potential crashes with 64-bit guests on 32-bit hosts (bug # 11979 )
GUI / seamless: properly handle mouse wheel scroll events
GUI, VBoxManage: When unregistering A VM, unregister Also the hard Disk Images Which are used exclusively (bug # 10311 )
GUI: prevent crashes under certain conditions on X11 hosts
3D: multiscreen fixes (incorrect mouse position, flickers)
3D Support: several fixes for the Windows WDDM video driver (multiscreen, seamless)
Snapshots: Snapshots work Made Live Again (bug # 9255 )
Teleportation: Made Again IT work (bug # 9455 )
VBoxManage: on snapshot take, - pause is default and - live is for doing live snapshots
VBoxSVC: don't crash on systems with many VLAN interfaces (Solaris hosts only)
Network: after the host resumes from suspend, disconnect and reconnect the virtual network cables to force renewing the DHCP leases for the guests. Only so Far Mac OS X hosts and Windows hosts (bug # 10063 ).
NAT: on name server changes force a reconnect of the virtual network cable to notify the guest (Mac OS X hosts only)
Mac OS X installer: keep previously installed Extension Packs on VirtualBox upgrade
Linux hosts / Guests: Linux 3.11 fixes (bug # 12001 )
Solaris hosts: fixed a potential kernel panic caused due to unexpected preemption due to logging.
Windows hosts: fixed an issue with USB2 devices being inaccessible when plugged into USB3 ports.
Linux Additions: added PCI device identifier to vboxvideo.ko fixing DRI Initialization Under Certain Conditions (bug # 11957 )
Linux Additions: fixed udev detection in the init script with Linux 3.x kernels
