VirtualBox 4.3.0.89960

VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

Some of the features of VirtualBox are:

  • Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
  • Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.

# 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
* 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 non-critical warnings and provide user with additional information)
* GUI: keyboard shortcuts management (input page of global preferences extended with possibility to edit general keyboard shortcuts for VirtualBox Manager and Virtual Machine)
* GUI: video capturing support
* Added USB touch device emulation
* Added experimental support for webcam passthrough complementing USB passthrough (see the manual for more information)
* Added SCSI CD-ROM emulation, including boot support
* VRDP: support for IPv6
* Guest Control: guest sessions now are running in dedicated, impersonated session processes (needs at least Guest Additions 4.3 installed)
* Guest Control: implemented IGuestFile support
* NAT: experimental virtual router mode: several VMs are attached to the same internal network and share one NAT service
# 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
* VMM: allow to activate VT-x while in SMX mode and provide more information if that is not possible
* GUI: update check uses https
* GUI: numerous minor internal cleanups and bug fixes
* GUI: HID LEDs synchronization when switching between guest window(s) and host (Mac OS X hosts only)
* GUI, VBoxManage: when unregistering a VM, also unregister the hard disk images which are used exclusively
* 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
* Teleportation: made it work again
* 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
* Main: extension pack framework can now support loading HGCM modules
* VBoxManage: list more information about hard disk/DVD/floppy media, and support the --long option to show really all available details
* 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 <all|sessions|processes|files>
* VBoxManage: added support for closing active guest sessions via guestcontrol session close --session-id <ID> | --session-name <name or pattern> | --all
* VBoxManage: added support for terminating active guest processes via guestcontrol process kill|close|terminate --session-id <ID>| --session-name <name or pattern> <PID> ... <PID n> or guestcontrol [p[s]]kill --session-id <ID>| --session-name <name or pattern> <PID> ... <PID n>
* VBoxManage: added support for watching guest sessions via guestcontrol watch
* VBoxManage: added modifyvm --triplefaultreset to make the VM reset on triple fault instead of triggering a Guru Meditation
* 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
* Mac OS X hosts: limited support for Mac OS X 10.9
* Mac OS X hosts: use a launchd script instead of the deprecated StartupItem mechanism
* Windows hosts: don't cause massive DPC latency (only on certain hosts; still needs improving)
* Windows hosts: consider symlinks when retrieving volume information
* 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)
* Windows Additions: fixed memory leak caused by WTSQuerySessionInformation() on Windows 2000 guests
* Windows Additions: ability to track guest user idle times through the newly introduced event IGuestUserStateChangedEvent
* Linux Additions: fixed udev detection in the init script with Linux 3.x kernels
