Download VirtualBox 5.1.26

The thirteenth update for VirtualBox version 5.1 has been released. 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, macOS, Linux and Solaris, and is able to guest operating systems to turn.

In version 5.1 of VirtualBox we find, among other things, new apic implementations that provide various performance improvements, there is improved support for Python 3 and the interface has been switched to Qt5. The following improvements have also been made in this update.

The following items were fixed and/or added:

• VMM: reset the TSC on VM reset to work around a Windows bug (bug #16643)
• Audio: fixed memory leak when enabled with VRDP connections (5.1.24 regression; bug #16928)
• Audio: fixed creation of too many sound sinks on Linux hosts when using the PulseAudio backend (bug #16938)
• Audio: implemented record gain registers for AC’97 emulation; those are needed for newer Ubuntu guests which rely on those when controlling gain and muting the recording (capturing) levels
• Storage: fixed hang when using the emulated NVMe controller with the SPDK (bug #16945)
• Mouse: double click was not working with a precision touchpad (bug #14632)
• Linux hosts: properly bring up host-only network interfaces with iproute (5.1.24 regression; bug #16911)
• Linux hosts: provide Python 3 libraries for deb/rpm packages
• Windows hosts: make it possible to use host-only networking without having bridged networking installed
• Windows guests: fixed automatic logons for Vista and newer Windows guests (5.1.24 regression; bug #16921)
