Qubes lack connectivity based on how they are started

Ok, here are all the things I did:

  1. recreated all templates based on debian-11-minimal
  2. recreated all qubes from scratch based on the new templates and then manually imported the respective settings and data
  3. recreated system and web template based on fedora-36-minimal

In all cases I get the same behavior:

  • the dispvm always has connectivity
  • the mail qubes always have connectivity
  • the other web qubes sometimes have, sometimes don’t … in two cases they lost connectivity while running (other qubes remained online)

I see no hints in dom0 logs.

I cannot overstate how stressful this is. This machine has been my daily driver for a long time. My setup is stable-stable. No tweaking not even installing new apps. I’ve been using it the way it was for months.

Karma?
