After applying the following config options on tempest.conf:
[load_balancer]
enable_security_groups = True
enforce_new_defaults = True
#admin_role = admin
RBAC_test_type = keystone_default_roles
#member_role = member
region = regionOne
enabled_provider_drivers = amphora:The Octavia Amphora driver.,octavia:Deprecated alias of the Octavia Amphora driver.,ovn:Octavia OVN driver.


There are more Octavia tempest tests that fail, but I am assuming that after we fix the tests I mentioned above, the other tests will be fixed too.


Version-Release number of selected component (if applicable):
RHOS-17.1-RHEL-9-20230131.n.2

How reproducible:
100%

Steps to Reproduce:
1. Run the tests mentioned above, either on jenkins, or locally


Actual results:
The tempest tests fail

Expected results:
The tempest tests should pass
