I'm glad to see you soulved the problem.

Some additional comments follow.

Strange. I'm still unable to understand whether this is a Suse specific
problem or is due to some other bug.

By the way, I assume you used "vclean --clean-all" instead.

This means that you have a line
in your lab.conf. Indeed, the collision domain for tap interfaces is
forced (you may assume it to be "tap"). Any tap interface in your lab
would automatically connect to that same collision domain. Therefore,
explicitly specifying an additional collision domain name for eth0 on
recursivo is correctly interpreted as a misconfiguration.

You are welcome!
It would be great if you could provide us with some more information
about your University, so that we can update the "success stories" page:

Thank you and regards,
