It shouldn't kill networking though. If a guest has two nics connected to the same host bridge (a reasonable configuration), and then connects these two nics through its own bridge, it creates the same sort of loop. If that kills networking, we have a guest-initiated DoS (not that the userspace-initiated DoS was much better).That's what STP is for.
The guest need not respect it. The host must survive network loopbacks. -- error compiling committee.c: too many arguments to function
