an open source application commonly used to measure latencies in
real-time systems. This real-time VM (RT_VM) uses inter-VM shared memory

The HMI_VM formats and presents the collected data as a histogram on a web
page shown by a browser. This guide shows how to configure, create, and
launch the two VM images that make up this application.
