Version 4.3.0 Beta 3 (2013-09-20)
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)
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 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 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 chapter 6.4, Network Address Translation Service
(experimental), page 95)
In addition, the following items were fixed and/or added:
VMM: properly handle NMIs on Linux hosts with X2APIC enabled
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)
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Settings: the per-VM hwvirtextexcl setting has been replaced by a global hwvirtexclusive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 <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
3D support: several fixes
3D support: several fixes for Mac OS X hosts
OVF: several fixes
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)
Linux Additions: fixed udev detection in the init script with Linux 3.x kernels
Windows guests: ability to track
