Code Issues Proposed changes

Workaround to avoid connectivity problems from ubuntu VM instances 

With some recent ubuntu release, routes to nameservers are added to VLAN
interfaces. This breaks some tests when they are executed in downstream
jobs because the affected VM instances are unable to reach the external
gateway
