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:
# show present state
[vagrant@vdsm ~]$ ip a

I don't think this STP parameter is exposed via engine UI; @Dominik
Holler , could you confirm ? What are our plans for it ?
STP is only available via REST-API, see
please find an example how to enable STP in
We have no plans to add STP to the web ui,
but new feature requests are always welcome on
