[Bug 2076916] [NEW] VMs cannot access metadata when connected to a network with only IPv6 subnets with the ML2/OVS and ML2/LB backends
Public bug reported:
While fixing https://bugs.launchpad.net/neutron/+bug/2069482 "[OVN] VMs
cannot access metadata when connected to a network with only IPv6
subnets", a neutron-tempest-plugin test case was proposed to make sure
in the CI system that VM's can access the metadata service over an IPv6
only network: https://review.opendev.org/c/openstack/neutron-tempest-
plugin/+/925928. While the new test case succeeds with the ML2/OVN
backend thanks to this fix
https://review.opendev.org/c/openstack/neutron/+/922264, it also showed
the following failure with the ML2/OVS and ML2/LB backends:
curl: (28) Failed to connect to fe80::a9fe:a9fe port 80: Connection
timed out
Steps to reproduce:
Recheck https://review.opendev.org/c/openstack/neutron-tempest-
plugin/+/925928 and see the logs for the ML2/OVS and ML2/LB jobs
How reproducible: 100%
