Bug Description

Running the specs/full_stack/next_deploy/newton mojo spec on xenial results in guests being unable to contact the gateway in 9/10 tests.

The issues shows itself as mojo being unable to ping the guest but digging into further shows the guest does not receive metadata or a dhcp address. Looking on the compute nodes and gateway node there are no gre tunnels being created. By default the cloud has L2 population enabled meaning that the gre tunnels *should* be created on demand.

Restarting neutron-openvswitch-agent on the compute and gateway nodes appears to fix the issue.

It seems a restart of neutron-openvswitch-agent on the gateway node is sufficient to fix the issue.

Was this resolved by using a larger instance for neutron-gateway?

Yes, it was. The issue was insufficient memory on the gateway instance.
