Question,

Is it expected to make a ping or ssh to an instance from an active controller?
I ask because I could from a compute to an instance.

Network namespaces are created and managed by Neutron agents which are only scheduled on compute nodes or all-in-one controller nodes. In this report, the configuration is multi-node, so the controllers will not have any neutron agents scheduled on them.

Please refer to the above bug for more information about namespaces. Namespaces should not be directly used for end-to-end testing.

On compute nodes $ ip netns can display content and can ping/ssh instances, so the corresponding test should be updated to indicate the restrictions.

Then I think this issue should be closed.
