Hello. I have been trying to figure out an issue for a very long time.
That issue relates to the ethernet and 10gb fc links that I have on my
cluster being disabled any time a migration occurs.
I believe this is because I need to have STP turned on in order to
participate with the switch. However, there does not seem to be any
way to tell oVirt to stop turning it off! Very frustrating.
After entering a cronjob that enables stp on all bridges every 1
minute, the migration issue disappears....
Is there any way at all to do without this cronjob and set STP to be
ON without having to resort to such a silly solution?
Vdsm exposes a per bridge STP knob that you can use for this. By
default it is set to false, which is probably why you had to use this
shenanigan.
You can, for instance:

I don't think this STP parameter is exposed via engine UI; @Dominik
Holler , could you confirm ? What are our plans for it ?
