Seems your all 3 polaris_external networks are having provider:network_type as flat. Delete all your networks and create networks fresh, then try to launch an instance.

will try this. does only one need to be flat? all three are provider networks....

Removed all external networks and reconfigured. Start with 1 and an internal, bring in a second (and more) external when you have the first figured out. After creation and test of one, create more.

I think the problem is that you are trying to do something without specifying which external network to attach to.

unfortunately he didn't bother to say what he was trying to do. Maybe create a floating ip.
