    Additional non-hardware required tests still running, but I would like to share the results
of the ones which require hardware.
    
    Test Environment
    * Management Server + MySQL on CentOS 7.1
    * Two KVM hosts on CentOS 7.1
    * Agent and Common RPMs built from source

> Sometimes, when trying to remove a network of a rVPC, I get the following error in the
router logs:

> 2. Remove the network
