[Bug 1896470] [NEW] OVN migration infrared plugin does not remove ML2OVS-specific templates

 

Public bug reported:

When running migration from ML2OVS to ML2OVN using infrared plugin some
ovs-specific templates remain in 'overcloud deploy' command. This is not
correct and can cause issues.

Example of overcloud-deploy-ovn.sh script:

cat overcloud-deploy-ovn.sh
#!/bin/bash

openstack overcloud deploy \
--timeout 100 \
--templates /usr/share/openstack-tripleo-heat-templates \
--stack overcloud \
--libvirt-type kvm \
--ntp-server clock1.rdu2.redhat.com \
-e /home/stack/virt/config_lvm.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/neutron-ovs-dvr.yaml \ <= REDUNDANT TEMPLATE
-e /home/stack/virt/network/network-environment.yaml \
-e /home/stack/virt/network/dvr-override.yaml \
-e /home/stack/virt/inject-trust-anchor.yaml \

-e /home/stack/ovn-extras.yaml \
-e /home/stack/container-images-ovn.yaml \
--log-file overcloud_deployment_24.log
