Public bug reported:
We run a juju managed Openstack Ussuri on Bionic. After updating neutron
packages from 16.3.0 to 16.3.1 all virtual routers stopped working. It
seems that most (not all) namespaces are created but have only the lo
interface and sometime the ha-XYZ interface in DOWN state. The
underlying tap interfaces are also in down.
neutron-l3-agent has many logs similar to the following:
