A while ago Cole reported that libvirt is exposing a long term bug in GLib's event loop that results in non-deterministic crashes: https://www.redhat.com/archives/libvir-list/2020-February/msg00422.html I kept forgetting to investigate it until now.

[PATCH 00/32] docs: convert formatdomain.html.in to rst and split it up
by Peter Krempa 29 Jul '20

29 Jul '20

This is full version of: https://www.redhat.com/archives/libvir-list/2020-July/msg00717.html where I've split out all the subelements into individual files. This version is also based on top of Pavel's rewrite to the meson build system to minimize his conflicts and also it was simpler to achieve what I wanted. You can fetch this from my repo including Pavel's patches. git fetch https://gitlab.com/pipo.sk/libvirt.git formatdomain-rst-meson Unfortunately the pipeline jobs for libvirt are broken on some targets for non-obvious reasons and for some weird reason the 'website' job is in the 3rd stage of the pipeline. Thus you don't get to see the final result until it get's fixed withoug compiling it yourself.
