Description of problem:
we need to cover the scenario test on migration sriov from ml2ovs to ovn based on this deployment : 

[New Test] SR-IOV from OSP 13 to OSP 16 with single VM with 2 interfaces
1.VM1 has SR-IOV VF with VLAN provider networks and L2 agent for DHCP services ( nor routing)
2.VM1 has OVS with VLAN provider networks and L2 Agent for DHCP/metadata services (no routing)
3.Migrate to OVN for SR-IOV this SR-IOV scenario
Version-Release number of selected component (if applicable):

Comment 5 Roman Safronov 2020-09-22 13:22:11 UTC

Migration to ML2OVN on SRIOV environment tested on RHOS-16.1-RHEL-8-20200903.n.0 and worked using the following guidelines(in addition to usual OVN migration instructions from the official documentation):

1. Add OS::TripleO::Services::OVNMetadataAgent to Controller role.
2. Copy overcloud_deploy.sh to overcloud-deploy-ovn.sh
3. Delete ML2OVS-specific templates from overcloud-deploy-ovn.sh
4. Add the following OVN-specific templates to the end of the overcloud deploy command:

-e /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-ovn-ha.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-ovn-sriov.yaml \
-e /home/stack/ovn-extras.yaml


Tested with workload using normal and direct (vf) ports. With direct-physical (PF port) we are blocked with this issue: Bug 1879546 - [OSP16.1]Migration from ML2OVS to ML2OVN fails in case some SRIOV PF/VF ports are in use
