Title:
  Issues with OVN-based Octavia

Status in OpenStack Snap:
  Incomplete
Status in ovn-octavia-provider package in Ubuntu:
  New

Bug description:
  Enabling Loadbalancer and CaaS in Sunbeam should ultimately result in
  a working K8s cluster and be used as any k8s cluster would be.

  Example 1.

  When istio is deployed it creates 3 load balancers ingress, egress and
  cni. Each of these is created seemingly without error however the
  status soon drops into 'error' state.

  Assuming its not user error it depends on where this goes:

  1) It is possible to work using OVN basd Ocatavia and its just that
  the cloud-controller/ingress-controller doesn't set it up correctly
  (the load balancer method doesn't get set to SOURCE_IP_PORT for
  example, possibly other issues) so its a bug there (where?)?

  2) This setup actually requires amphora based Octavia, making this a
  wishlist feature request (in which case close and add this reasoning
  to https://bugs.launchpad.net/snap-openstack/+bug/2044567). I cannot
  find anything that says it won't work with OVN based Octavia, however
  I have not seen any confirmation it does.

  3) Its both cases. In which case twice the fun.

  Example 2

  Creating Jenkins using Helm chart as per https://charts.jenkins.io,
  setting the option as below creates a LoadBalancer in Octavia the is
  similar to the above in that the pool is offline, there is no lb
  method set.

    set {
      name = "controller.serviceType"
      value = "LoadBalancer"
    }

  Example 3

  Following https://github.com/kubernetes/cloud-provider-
  openstack/blob/master/docs/openstack-cloud-controller-manager/expose-
  applications-using-loadbalancer-type-service.md results in no response
  from the curl command.
