VirtualBox 4.3.0 RC1 + Extension Pack | 103MB


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".
Installation:
Run VirtualBox, go to the File menu "Properties" Plug-ins and add the downloaded file has the extension. Vbox-extpack

Additional Information:
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.

Main Features:
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.

Change log:
Version 4.3.0 Release Candidate 1 (10/08/2013)
This is a major update. The following major new features were added:
VMM: major rewrite of the VT-x code and the AMD-V code including many bug fixes and performance improvements (for example bug # 9659)
VMM: introduced a lightweight instruction interpreter for situations not handled by hardware virtualization
GUI: extended messaging mechanism (new non-modal popup overlays used to show noncritical warnings and provide user with additional information)
GUI: keyboard shortcuts Management (input Page of global preferences with Extended
Possibility to edit General keyboard shortcuts for VirtualBox Manager and Virtual Machine)
GUI: video capturing support (bug # 4766)
Added USB touch device emulation
Added SCSI CD-ROM emulation, including boot support
VRDP: Support for IPv6
?
Control guest: guest Sessions are now running in Dedicated, impersonated Session Processes
(needs at Least 4.3 Guest Additions installed)
?
Guest Control: Implemented IGuestFile Support
?
NAT: Experimental Virtual router mode: Several VMs are Attached to the Same Internal network and one Share NAT Service (See Chapter 6.4, Network Address Translation Service
(Experimental), Page 95)

In addition, the following items were fixed and / or added:
VMM: significantly improved performance of NetWare 5.x/6.x guests on host systems without nested paging support
VMM: fixed losing host NMIs while in VT-x guest-context
VMM: changed order of actions in emulated task switch (bug # 10532)
GUI: update check uses https
GUI: numerous minor internal cleanups and bug fixes
GUI, VBoxManage: when unregistering a VM, also unregister the hard disk images which are used exclusively (bug # 10311)
GUI: use the number of physical presented processor cores instead of the number of logical processor cores to check if the users assigned too many virtual CPUs to the guest
Snapshots: made live snapshots work again (bug # 9255)
Teleportation: made it work again (bug # 9455)
? Storage: implemented AHA-154x compatibility mode in the emulated BusLogic SCSI HBA
Storage: significantly improved performance of large ATAPI PIO transfers (BeOS, Minix 3 guests affected)
Storage: added floppy formatting emulation (NB: cannot be used to change existing media geometry)
Settings: global and per-VM default frontend configuration, useful to select the use of alternative VM frontends
Settings: limit depth of snapshot tree to 250 levels, as more will lead to decreased performance and may trigger crashes
Settings: the per-VM hwvirtextexcl setting has been replaced by a global hwvirtexclusive property
Main: new event queue implementation which does not use the host's native event queue for processing VirtualBox events anymore
Main: eliminate the use of SysV semaphores on all host OSes other than Windows, namely Linux, Solaris and Mac OS X, with the consequence that no system reconfiguration is needed to run more than approximately 100 VMs
Main: use the XDG standard configuration folder instead of. VirtualBox on systems where it is appropriate (bug # 5099)
Main: extension pack framework can now HGCM Support loading modules, Contributed by Jeff Westphal
?
VBoxManage: list more Information About hard Disk / DVD / Floppy Media, and the Support
- Long option to Show All available details really
? VBoxManage: added support for optional command line parameters for the automatic
Guest Additions update
VBoxManage: added support for listing active guest sessions, guest processes and / or guest files via guestcontrol list
VBoxManage: added support for closing active guest sessions via guestcontrol session close - session-id | - session-name | - all
VBoxManage: added Support for active guest Terminating Processes Via guestcontrol Kill Process | close | terminate - Session-ID | - Session-name ... or guestcontrol [P [s]] Kill - Session-ID |
- Session-name ...
VBoxManage: added support for watching guest sessions via guestcontrol watch
3D support: several fixes
3D support: several fixes for Mac OS X hosts
OVF: several fixes
Extpack Installer: make it work if the file is located in a folder with special characters
Keyboard: fix for reporting key sequences like Ctrl + Alt + Del for the USB keyboard emulation
Shared Clipboard/X11: support for BMP-format images, contributed by François Revol
Windows hosts: don't cause massive DPC latency (only on certain hosts; still needs improving; bug # 6242)
Windows hosts: consider symlinks when retrieving volume information (bug # 11962)
Windows hosts: fixed an issue with USB2 devices being inaccessible when plugged into USB 3.0 ports
Windows Additions: fixed misbehavior with guest display power management (WDDM driver only; bug # 11170)
Windows Additions: fixed memory leak caused by WTSQuerySessionInformation () onWindows 2,000 guests (bug # 12072)
Linux Additions: fixed udev detection in the init script with Linux 3.x kernels
Windows guests: ability to track guest user idle times through the newly introduced event IGuestUserStateChangedEvent
