Virtualbox Update Now Available

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.

VirtualBox features include:

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 changes have been undertaken in this latest version of VirtualBox:

* The following items were fixed and/or added:
– VMM: fixed restoring 32-bit FPU state on 64-bit capable VMs and restoring guest FPU in raw-mode VMs (4.3 regression)
– GUI: properly restore normal/scale mode guest-screen size after exiting full-screen/seamless mode
– GUI: mini-toolbar should provoke less artifacts/conflicts with 3D guest rendering
– GUI: Mac OS X: Native full-screen multi-screen transition was able to blackout host-screens for nearly minute
– GUI: X11: Modern window managers should now use native full-screen multi-screen mapping API
– GUI: added extradata item for configuring the mouse capture behavior, see the manual for more information
– Storage: fixed a VBoxSVC crash when querying an iSCSI target with authentication configured (4.3.14 regression)
– Storage: fixed a rare data corruption during reads if another allocating write is running concurrently and accesses the same range
– Storage: fixed a rare crash for certain VHD images from other products
– Storage: fixed a rare release assertion when using the AHCI controller
– Floppy: fixed read errors and guest memory corruption when running under control of QEMM
– 3D: added experimental support for rendering on offline GPUs for Mac OS X host
– 3D: fixed white window appearing on entering FullScreen mode on OSX host
– 3D: fixed video recording support for 3D data regression
– 3D: fixes for MS Office 2013 support
– 3D: several fixes
– Bridged Networking: improved IPv6 support when bridging to a wireless interface
– NAT: prevent internal DNS service from stuck in host-resolver mode when host was switched from one network to another one while host was sleeping (Mac OS X hosts)
– NAT: preserve DF (if possible) and TOS when proxying outbound UDP datagrams
– NAT: don’t let multicast datagrams out
– NAT: fixed handling of large incoming UDP datagrams on Windows hosts
– NAT: fixed handling of the RFC 1533 DHCP PAD option
– NAT Network: fixed inbound half-close on Windows hosts
– NAT Network: preserve IPv4 DF (if possible), TTL, TOS and IPv6 Hop Limit when proxying outbound UDP datagrams
– VRDP: fixed a rare crash when using remote audio input
– USB: fixed several regressions from 4.3.14
– Audio: made the HDA sound emulation work with certain OSX guests (e.g. Mountain Lion)
– Windows hosts: fixed startup problems on certain Windows hosts due to conflicts with anti-virus software (4.3.14 regression)
– Windows hosts: fixed 4.3.14 regression whereby AltGr stopped working for some people
– X11 hosts: made the extra key on Brazilian Thinkpads work
– X11 hosts: fixed a problem of input focus cycles and immediately released key presses in full screen mode
– Linux hosts: fixed flooding the kernel log with USB related messages when passing through certain USB devices to a VM
– Linux guests: stop applications crashing when drm_wait_vblank is called
– Linux guests: fix a crash in gnome-session
– X11 guests: do not start VBoxClient over an SSH connection
– X11 guests: added support for X.Org Server 1.16
– X11 guests: fixed a wrong parameter in the video driver which caused problems with full-screen X11 clients
– VirtualKD: introduced stub/loader device for speeding up Windows kernel debugging
