In the genre, several solutions are known for their ease of use, such as VMware Workstation , Parallels Desktop or Microsoft Virtual PC 2007 SP1.

VMM: reset the TSC on VM reset to work around a Windows bug.
Audio: fixed memory leak when enabled with VRDP connections (5.1.24 regression).
Audio: fixed creation of too many sound sinks on Linux hosts when using the PulseAudio backend.

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 (5.1.24 regression).
Linux hosts: provide Python 3 libraries for deb/rpm packages.
