Oracle heeft versie 4.3.22 van VirtualBox uitgebracht. VirtualBox kan worden gebruikt om andere besturingssystemen in een virtuele omgeving op een computer te installeren. Op die manier is het mogelijk om verschillende besturingssystemen op dezelfde hardware naast elkaar en tegelijkertijd te gebruiken. VirtualBox is beschikbaar voor Windows XP en hoger, OS X, Linux en Solaris, en is in staat om een groot aantal gastbesturingssystemen te draaien.

In versie 4.3 van VirtualBox is onder meer de complete virtualisatiecode herschreven, wat diverse problemen heeft verholpen en ook verschillende prestatieverbeteringen laat zien. Verder zijn er videocapturing en ondersteuning voor ipv6, kunnen diverse virtuele machines die op dezelfde computer draaien nu via het interne netwerk met elkaar communiceren en is er ondersteuning voor multitouchschermen. Deze twaalfde update bevat daarnaast nog de volgende verbeteringen:The following items were fixed and/or added:

  • VMM: refined measurement of TSC frequency on the host, improves timekeeping for guests
  • VMM: decreased CPU load resulting from guest MMIO writes to the virtual APIC
  • VMM: fixed interception of debug exceptions, observed while using the dbx debugger on Solaris guests (VT-x only)
  • GUI: 3D overlay window positioning code improved, fixed potential misplacement of 3D accelerated guest graphics content
  • GUI: fixed accident SSL authentication failures during update check on Windows hosts (bug #12969)
  • GUI: never send the “ACPI power” keyboard scancode to the guest, we have the ACPI power button for that
  • GUI: was unable to properly restore seamless mode VM from snapshot/saved-state under some circumstances
  • VBoxHeadless: don’t crash if 3D is enabled in the VM settings (bug #10250)
  • ATA: fixed several passthrough issues (bugs #12310, #1360)
  • Audio: fixed DirectSound failure when the the host has no audio input device (Windows hosts only; bug #9205)
  • SB16: fixed compatibility issue (bug #13769)
  • Storage: fixed broken CD/DVD passthrough when using the IDE controller (bug #12310)
  • NAT: new ping proxy for Windows hosts (bug #11871)
  • NAT: Properly report outbound connect(2) failures to guest with TCP RST or ICMP (bug #10525)
  • NAT Network: no need for frequent wakeups in VBoxNetDHCP and VBoxNetNAT (bug #11681)
  • Host-only adapter: prevent Windows from creating an “Unidentified network” (bug #9688)
  • Bridged Networking: don’t leak host-to-guest traffic to the wireless network when bridging to a wireless interface (bug #13714)
  • Main: fixed a possible race when changing the medium leading to a deadlock under rare conditions (bug #13722)
  • VBoxManage: fixed return code if starting a VM failed (bug #13773)
  • API: fixed 2 deadlock opportunities related to medium handling (bugs #13789, #13801, thank you Alexander Urakov)
  • API: fixed bug in XPCOM which created too few worker threads, sporadically resulting in a deadlock (bug #13802, thank you Alexander Urakov)
  • SDK: fixed a garbage collection leak in the Python VirtualBox webservice API binding (bug #13817)
  • Linux hosts: fixes for activated SMAP (Broadwell and later, bug #13820)
  • X11 guests: prevent unwanted hiding of guest screens on multi-monitor guests (bug #13287)
  • X11 guests: added support for X.Org Server 1.17
  • X11 Additions: fixed a memory leak in VBoxService if libdbus is available but dbus-daemon isn’t running (bug #13770)
  • Windows Additions: prevent VBox WDDM driver from loading if host reports weak OpenGL capabilities. 3D content now can be shown over Remote Desktop connection.
  • Winodws Additions: some fixes for recent Windows 10 Previews
  • Linux Additions: fixed a compatibility issue with 64-bit Linux 2.4 kernels
  • Linux Additions: fixed a potential use-after-free when unloading the VBoxGuest module
