Hi dementor,
I just wanted to reply so you know this has been seen.
I really want to take a look at it and keep it in my inbox, but this week I'm way too busy and won't get to it :-/
Until I get to it it would be nice if you could outline "When i try to switch on existing not working bridge virbr0" a bit more.
is virbr0 already existing, if so who/how was it created.
What do you switch to it - a guest config switching from a former network to use that?
Or a network definition to use virbr0.
Since it is a UI thing a screenshot or video often helps to disambiguize.
Do the same actions work if you use virsh as a commandline tool to do so?
