The MidoNet host agent is a daemon that runs on each of the compute nodes, reads the network configuration from zookeeper and configures the Open vSwitch kernel datapath for the virtual networking.

This charm installs the MidoNet Host Agent which is the user-space component that interfaces with Apache Zookeeper to read the virtual network configuration and sets up the kernel Open vSwitch data path flows accordingly. In OpenStack deployments, the MidoNet host agent constitutes Midonet's neutron agent.
The host agent is a daemon that, as aforementioned, uses Apache Zookeeper for the distributed network configuration data store. Additionally it uses Apache Cassandra for storing ephemeral network data. This charm will install the version (upstream opensource or downstream MEM) that its midonet-repository relation determines.
juju deploy midonet-host-agent
then relate to a puppet repository config provider juju add-relation midonet-host-agent midonet-repository or juju add-relation midonet-host-agent mem-repository
then make it connect to the distributed data
juju add-relation midonet-host-agent zookeeper juju add-relation midonet-host-agent cassandra
Then you can connect it to the midonet-api so that it will be added to the default tunnel zone: juju add-relation midonet-host_agent midonet-api Finally, if this is for a compute host, relate it to nova-compute
juju add-relation midonet-host-agent:neutron-plugin nova-compute:neutron-plugin
