qrexec sequences

Published on November 28th, 2017

Qubes' qrexec mechanism is tricky. The documentation runs through some examples of how the various parts fit together, but I thought it might be easier to understand with some sequence diagrams.

Here are a couple of diagrams representing dom0-to-domX and domY-to-domX qrexec applications, taken from the documentation linked above. These necessarily incomplete, but helped me more clearly understand how things work.
