Download VirtualBox 4.3.28

While work is already underway on VirtualBox version 5.0, Oracle has released an update for version 4.3. VirtualBox can be used to install other operating systems in a virtual environment on a computer. In this way it is possible to use different operating systems on the same hardware side by side and at the same time. VirtualBox is available for Windows XP and above, OS X, Linux, and Solaris, and is capable of many guest operating systems to turn.

In version 4.3 of VirtualBox, the complete virtualization code has been rewritten, among other things, which has fixed several problems and also shows several performance improvements. There is also video capture and support for ipv6, various virtual machines running on the same computer can now communicate with each other via the internal network and there is support for multi-touch screens. This fifteenth update also contains the following improvements:

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 (eg 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 (eg 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)
