Updated the diagram on the wiki page. To keep noise low, I won't send emails on further changes to that wiki page.

Ah, that's '-m slow', not '--slow'. Yeah, that works for qos-test. I added the '-m slow' switch to the wiki page as well. For now I can live with that, as I am more commonly calling qos-test directly. But it would be nice if the slow tests would make it into the general chain of all QEMU tests accordingly again. > The latter was discussed on IRC last year but I don't know if > anyone has tried to investigate this yet. > > Nov 24 11:36:53 <groug> th_huth, Hi.
