VirtualBox 4.3.0 Build 89960 Final

"VirtualBox 4.3.0 Build 89960 Final"

VirtualBox is a general-purpose full virtualizer for hardware. Targeted at server, desktop and embedded use, it is now the only professional quality virtualization solution that is also Open Source Software. VirtualBox is a powerful virtualization product for enterprise as well as home use. VirtualBox provides are useful for several scenarios: Running multiple operating systems simultaneously. VirtualBox allows you to run more than one operating system at a time.




This way, you can run software written for one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot to use it. Since you can configure what kinds of “virtual” hardware should be presented to each such operating system, you can install an old operating system such as DOS or OS/2 even if your real computer’s hardware is no longer supported by that operating system.

Software vendors can use virtual machines to ship entire software configurations. For example, installing a complete mail server solution on a real machine can be a tedious task. With VirtualBox, such a complex setup (then often called an “appliance”) can be packed into a virtual machine. Installing and running a mail server becomes as easy as importing such an appliance into VirtualBox.

Testing and disaster recovery. Once installed, a virtual machine and its virtual hard disks can be considered a “container” that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts. On top of that, with the use of another VirtualBox feature called “snapshots”, one can save a particular state of a virtual machine and revert back to that state, if necessary. This way, one can freely experiment with a computing environment. If something goes wrong (e.g. after installing misbehaving software or infecting the guest with a virus), one can easily switch back to a previous snapshot and avoid the need of frequent backups and restores. Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time. You can delete snapshots while a VM is running to reclaim disk space.

Infrastructure consolidation. Virtualization can significantly reduce hardware and electricity costs. Most of the time, computers today only use a fraction of their potential power and run with low average system loads. A lot of hardware resources as well as electricity is thereby wasted. So, instead of running many such physical computers that are only partially used, one can pack many virtual machines onto a few powerful hosts and balance the loads between them.

Changes in VirtualBox 4.3.0 (released 2013-10-15):

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 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 (bug #4766)
– 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 (see the manual for more information)
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)
– 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 (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 support loading HGCM modules, contributed by Jeff Westphal
– 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
– VBoxManage: added support for closing active guest sessions via guestcontrol session close –session-id | –session-name | –all
– VBoxManage: added support for terminating active guest processes via guestcontrol process kill|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
– VBoxManage: added modifyvm –triplefaultreset to make the VM reset on triple fault instead of triggering a Guru Meditation (see the manual for more information)
– 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
– Mac OS X hosts: limited support for Mac OS X 10.9 (Mavericks)
– Mac OS X hosts: use a launchd script instead of the deprecated StartupItem mechanism (bug #8940)
– 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() on Windows 2000 guests (bug #12072)
– 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
