How do I get the series of commands run? From the logs it looks like 
there is a creation of a bridge, eth0 enslavement, admin down on bridge 
and then delete of the bridge. When I run those commands in a VM I do 
not hit the usage count of 1, so I am clearly missing some commands.

Thanks for the report,
David
