Support for cloning of VMs (bug #5853, see chapter 1.12, Cloning virtual machines, page
26)

GUI: enhanced wizard for creating new virtual disks

GUI: new wizard for copying virtual disks

GUI: keep the aspect ratio in scale mode (Windows and OSX hosts only; bug #7822)

VMM: raised the memory limit for 64-bit hosts to 1TB

Experimental support for PCI passthrough for Linux hosts, see chapter 9.6, PCI passthrough,
page 145

Windows guests: Experimental WDDM graphics driver

Guest Additions: modules and features now are represented as facilities to have a common
interface for frontends

Networking: new network attachment mode “Generic Driver”, which offers an open plugin
architecture for arbitrary and separately distributable virtual network implementations

New Networking Mode UDP Tunnel: allows to interconnect VMs running on different hosts
easily and transparently, see chapter 6.2, Introduction to networking modes, page 85

Experimental support for SATA hotplug added. Currently only supported for hard disks and
only with VBoxManage.

Solaris hosts: New Crossbow based bridged networking driver for Solaris 11 hosts (build
159 and above).

In addition, the following items were xed and/or added:

VMM: more SMP timer xes

VMM: xed sporadic recompiler crashes with SMP guests

VMM: many small xes

GUI: when reverting to a snapshot, ask for taking a snapshot of the current state

GUI: added a View menu

GUI: added a setting for the promiscuous mode policy for internal networks, bridged net-
works and host-only networks

GUI: the VM description is editable during the runtime of a VM (bug #1551)

GUI: added proxy settings (bug #2870)

GUI: made the number of SATA ports congurable

GUI: decrease time before showing the VM conguration dialog

VBoxManage: more convenient conguration of storage controller attachments by auto-
matically determining the port or device parameter when a storage controller has only one
port or device per port

VBoxManage: changed syntax of the guestcontrol command group, xed various bugs,
removed obsolete options

VBoxBalloonCtrl: new service for automatic dynamic adjustment of the balloon size for
running VMs

Settings: machine names and snapshot names are not allowed to be a valid UUID

Settings: provide better diagnostics if a single medium is used twice in a VM conguration

Settings: provide better diagnostics for errors in medium create/merge/clone operations,
and x memory leaks in error cases

Storage: ATA/SATA drives can be marked as non-rotational, i.e. the guest OS will detect
them as a SSD if supported, which can improve performance

Storage: virtual CD/DVD images will be detached if the guest ejects the medium, unless
the drive is marked to handle ejects only on a temporary basis

Storage: the medium UUID can be changed again when attaching a medium for the rst
time, which allows using images which are exact duplicates including the UUID

Storage: xed possible data corruption under certain circumstances with VHD and Parallels
images (bug #9150)

Storage: xed unnecessary expansion when cloning differential images in VDI format

Storage: xed detection code to handle empty les for VDI and VMDK format

Storage: xed access to CD/DVD images beyond 4GB when using the SATA controller (bug
#8592)

Floppy: several bugs have been xed

Floppy: make it possible to unmount a host oppy disk (bug #6651)

BIOS: disk-related structures are now checksummed correctly (bug #8739)

USB: many xes for the Windows USB host driver

NAT: reduced memory footprint

Networking: xed the problem with segmentation ofoading when several VMs are trans-
mitting in parallel

Networking: workaround for a bug in wireshark when operating directly on a capture le
created by VirtualBox

Serial: announce the serial devices in the ACPI tables to make Windows guests nd the
virtual hardware (bug #7411)

VRDP: support for TLS connections

VRDP: support for multimonitor client congurations with MS RDP clients

3D support: xed GL_VERSION string for different locales (bug #8916)

Webservice: xed timeout handling with HTTP 1.1 keepalive, and be more robust when
connections fail

VBoxSVC: xed regression when several clients trigger autostart simultaneously

Main: xed incorrect handling of the medium location for media which are not le based
(e.g. iSCSI), which resulted in confusing location values in many places

JAX-WS client bindings: xed resource leak

Sources: xed USB 2.0 support using extension packs for non-ofcial builds

Mac OS X hosts: xed non-VT-x mode on Lion hosts

Windows hosts: xed copy’n’paste in the GUI and for the VM window (bug #4491)

Windows hosts (64-bit only): enabled removing of all mediums when removing a VM

Windows hosts (64-bit only): enabled live snapshot deletion

Solaris hosts: xed preemption issue with Solaris 11 hosts (builds 166 and above)

Guest Additions: improved driver installation on Windows guests

Guest Additions: xed high CPU usage while executing guest programs from the host

Solaris Additions: xed automounting of shared folders (bug #8014)

Added support for Intel Media SDK 3.0
Sync with latest MediaInfo interface change (so that MediaInfo can be finally updated)
Fixed video track ID retrieving bug
Fixed muxer absent bug in x64 version
