3. Simulate connection loose on "public" nic of primary controller
by removing the corresponding interface of the bridge on the host
There was a similar issue with split brain scenarios reproducing and there was a conclusion made that in virtual environments manipulations with interfaces are really bad way to simulate real HW cases (there are no carrier down notifications). AFAIK, the decision made was to put down the bridge, not an interface - but I'm not sure if putting it out of bridge would work as well. So please, try to reproduce the same issue by putting the public bridge in down state or even better - at real HW, if it is possible
