This is a test the customer ran on his environment:
This is the port at the moment:
$ sudo podman exec -ti ovn-dbs-bundle-podman-2 ovn-nbctl list logical_switch_port octavia-lb-5279d85e-3c98-46ca-aea5-58b898db0386

when running openstack port set --device-owner "" octavia-lb-5279d85e-3c98-46ca-aea5-58b898db0386
I can see it recover:
ovn-nbctl list logical_switch_port octavia-lb-5279d85e-3c98-46ca-aea5-58b898db0386

parent_name : []
port_security : ["fa:16:3e:bc:8e:6c 10.226.128.77"]
tag : []
tag_request : []
type : virtual
up : true
also the nat is correct now:
ovn-nbctl lr-nat-list neutron-0e650979-0c96-4fe7-88b5-929451c29931 | grep 101
dnat_and_snat 172.18.144.101 10.226.128.77 fa:16:3e:44:8a:2a 926ae169-72ce-4d75-926b-7ed6bcb44ec8
if I move back to openstack port set --device-owner "Octavia" octavia-lb-5279d85e-3c98-46ca-aea5-58b898db0386
I see again the type being empty:
options : {mcast_flood_reports="true", requested-chassis=""}
parent_name : []
port_security : ["fa:16:3e:bc:8e:6c 10.226.128.77"]
tag : []
tag_request : []
type : ""
up : false
now trying ovn-nbctl lsp-set-type 926ae169-72ce-4d75-926b-7ed6bcb44ec8 virtual, logical port and nat become:
options : {mcast_flood_reports="true", requested-chassis=""}
parent_name : []
port_security : ["fa:16:3e:bc:8e:6c 10.226.128.77"]
tag : []
tag_request : []
type : virtual
up : false
$ sudo podman exec -ti ovn-dbs-bundle-podman-0 ovn-nbctl lr-nat-list neutron-0e650979-0c96-4fe7-88b5-929451c29931 | grep 101
dnat_and_snat 172.18.144.101 10.226.128.77
so ovn-nbctl lsp-set-type <vip-port-id> virtual does not seem like a valid workaround:
the lsp still has up=false
options:virtual-ip and virtual-parents are missing from the lsp
external_mac is still missing from the nat
also in the case I mention
At the moment the traffic is still sent to the chassis hosting the Amphora VM though.
I think this a mistake. I double checked and the traffic is sent to the L3 gw router.
I am more confident with setting openstack port set --device-owner "", on the loadbalancer having issues.
Also this behavior does not affect all the load balancers, setting device-owner to "" then back to Octavia on other load balancer ports does not break the virtual type, it's weird.
