VirtualBox 4.3.28

virtualbox

VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. 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.

VirtualBox 4.3.28 is a maintenance release. The following items were fixed and/or added:

  • VMM: fixed a Guru Meditation when rebooting certain guests (for example Solaris doing fast reboot) by fixing the implementation for INIT IPI
  • VMM: added some information for diagnosing rare VERR_VMX_INVALID_VMXON_PTR Guru Meditations (VT-x only)
  • GUI: HID LEDs sync: prevent synchronization if VM window has no focus (Windows and Mac OS X hosts only)
  • GUI: fixed drag and drop moving the cursor between guest screens on certain hosts
  • 3D: fixed a crash on restoring the VM state on X11 hosts (bug #12737)
  • 3D: fixed a crash on Linux guest shutdown (bug #12772)
  • VRDP: fixed incompatibility with rdesktop 1.8.3
  • VRDP: fixed listening for IPv6 on some systems (bug #14038)
  • Storage: don't crash if creating an asynchronous I/O context fails (e.g. when starting many VMs) and show a proper error message
  • Floppy: several fixes
  • Audio: improved the behavior of the volume control for the HD audio device emulation
  • USB: increase the number of supported drivers from 3 to 5 (Windows hosts only)
  • PS/2 keyboard: synchronize the LED state on VM restore (Windows and Mac OS X hosts only)
  • NAT Network: when running multiple NAT networks with multiple VMs, only stop the respective services when stopping VMs (bug #14090)
  • NAT: don't kill UDP bindings on ICMP errors (bug #13475)
  • NAT: bandwidth limit now works properly with NAT (bug #11485)
  • BIOS: fixed the returned size value of the VBE 2.0 PMI function 0Ah (4.2.0 regression; bug #14096)
  • Guest Control: fixed parameter quoting in Windows guests (bug #13157)
  • Webcam passthrough improvements for Linux (V4L2) hosts to support more webcam models
  • API: don't fail starting a VM with VBOX_E_INVALID_OBJECT_STATE under certain conditions (bug #13617)
  • API: be more verbose on VBOX_E_INVALID_OBJECT_STATE if a medium is attached to a running VM (bug #13560)
  • API: fixed a bug which could result in losing certain screen resize events with multi-monitor guests
  • rdesktop-vrdp: fixed path to the keymaps (bug #12066)
  • rdesktop-vrdp: switch to version 1.8.3
  • Windows hosts: more hardening fixes (e.g. bugs #14051, #14052)
  • Linux hosts: another fix for activated SMAP on Linux 3.19 and newer (Broadwell and later; bug #13961)
  • Linux hosts: Linux 4.1 compile fix (bug #14081)
  • Solaris hosts: fixed using of VNIC templates with Crossbow based bridged networking to be compatible with vanity interface names
  • Mac OS X hosts: fixed crash during VM termination under rare circumstances
  • Windows Additions/WDDM: improved video memory utilization and allow more/bigger guest screens with large resolutions (including HiDPI)
  • X11 Additions: prevent flickering when updating mouse cursor
  • Solaris Additions: fixed incorrect usage of 'prtconf' while installing Guest Additions (Solaris 10 only)
