Oracle VirtualBox 5.1.26 Released with Audio / Network fixes

A new maintenance release of Virtualbox 5.1 series, Virtualbox 5.1.26, was released hours ago with various bug fixes to audio, Linux network interface, etc.

Virtualbox 5.1.26 changelog:

• VMM: reset the TSC on VM reset to work around a Windows bug
• Audio: fixed memory leak when enabled with VRDP connections
• Audio: fixed creation of too many sound sinks on Linux hosts when using the PulseAudio backend
• 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
• Mouse: double click was not working with a precision touchpad
• Linux hosts: properly bring up host-only network interfaces with iproute
• 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
