VirtualBox 4.3.8 RC1

By Oracle  (Open Source)
User Rating

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 items were fixed and/or added:
* VMM: more work on improving the emulation of certain MSR registers
* VMM: fixed a VERR_INVALID_RPL Guru Meditation when booting certain guests
* VMM: experimental support for SSE 4.1 / SSE 4.2 passthrough
* VMM: fix for recent Linux kernels with software virtualization
* GUI: experimental HID LEDs synchronization for Windows hosts
* GUI: warn the user if the Oracle Extension Pack is not installed and the user tries to activate the remote display feature

* GUI: network adapter cables can now be connected/disconnected directly through the run-ning virtual machine Devices / Network menu a Network status-bar indicator

* GUI: better error message if appliance import fails
* VBoxManage: when exporting an appliance, support the suppression of MAC addresses, which means they will be always recreated on import, avoiding duplicate MAC addresses for VMs which are imported several times
* Storage: fixed a VM hang during suspend under certain circumstances if the AHCI con-troller is used
* AHCI: fixed a bug which resulted in Windows XP guest hangs if a SATA CDROM is attached
* AHCI: fixed a Guru Meditation under certain conditions

* AHCI: disk hotplugging fixes
* NAT: transparent handling of host sleep/resume and network configuration changes if the dnsproxy is enabled or if the hostresolver is used
* NAT: fixed crash and misbehaviour under some circumstances with ICMP packets having TTL=1
* NAT Network: fixed IPv6 reassembly
* NAT Network: ping proxy implemented
* OVF: fixed reading of the OVF 0.9 section element (4.3 regression)
* OVF: several fixes
* 3D: several fixes, multiscreen fixes
* 3D: include 3D content in captured videos
* 3D: include 3D content in captured screenshot
* VGA: proper handling of legacy graphics modes if the Guest Additions are active
* USB: fixed crash during isochronous transfer under rare circumstances
* BIOS: better disk geometry handling of SCSI drives
* API: fix crashes in Java API clients using the XPCOM binding, happened with output pa-rameters only
* VBoxSVC: documented the handling of host power management events and added an extradata item for configuring the handling of the battery-low event
* VBoxSVC: fixed a bug which could trigger a crash if a VM snapshot was restored the second time and the VM has associated bandwidth groups
* Shared Folders: fixed a failure to restore transient shared folders when starting a VM from a saved state
* Mac OS X hosts: fixed issue when the application icon was frozen in the dock if the bridging interface was not connected to a network
* Linux hosts: also consider the physical package ID when determining the number of physical CPU cores
* Linux hosts / guests: don’t warn in kernel log if memory allocation fails
* Solaris hosts: fixed the autostart SMF script
* Windows hosts: fixes for non-ANSI code page user names and similar environment contents
* Windows hosts / guests: fixed setting and using a guest user’s process environment variables (relevant for Guest Control)
