When labtestvirt2003 was setup in T166237: rack/setup/install labtestvirt2003 I must have failed to note that it needed the eth1 interface connected. Our 'labvirts' traditionally use eth0 for the host and management traffic, and eth1 for tenants. Additionally we are close to piloting eth2 for vxlan use cases so seems ideal to get it done at one time :)
eth0 is setup and good to go but at the moment no tenants have connectivity as eth1 is not connected.
eth0 status checked with lldpcli show neighbors and
interface-range vlan-labs-hosts1-b-codfw { member ge-1/0/11;
eth1 is 30:e1:71:60:e9:7d
