set up ovs test env

./generate-bundle.sh --name ovs -s focal --num-compute 1 --ml2-ovs --run
./configure
source novarc
./tools/instance_launch.sh 1 jammy

prepretion

juju config neutron-gateway instance-mtu=1300
juju config neutron-openvswitch instance-mtu=1300

# Deploy ovn-central, ovn-chassis(on all neutron-openvswitch units), ovn-dedicated-chassis(on all neutron-gateway units) and vault
juju deploy ovn-central --series focal -n 3

# ovn-chassis is for every neutron-openvswitch (ovn-chassis is subordinate charm of nova-compute so there is no '--to' here)
juju config neutron-openvswitch bridge-mappings
juju config neutron-openvswitch data-port
source ~/novarc

   --config bridge-interface-mappings='br-data:ens7' --config ovn-bridge-mappings=physnet1:br-data -n 1 --to 7

juju deploy --series focal vault --channel 1.7/stable

Perform the migration

juju config neutron-openvswitch firewall-driver=openvswitch

juju run-action neutron-gateway/0 pause

# Enable the Neutron OVN plugin, Wait for the deployment to settle.

juju run-action neutron-api/0 pause
# Perform initial synchronization of the Neutron and OVN databases

# Perform Neutron database surgery to update network_type of overlay networks to ‘geneve’
juju run-action neutron-api-plugin-ovn/0 offline-neutron-morph-db

juju run-action neutron-api/0 resume

# Migrate hypervisors and gateways
juju run-action neutron-openvswitch/0 cleanup
juju run-action ovn-chassis/0 resume
