Failures with FlatManager

Bug Description

When using FlatManager for networking, the /os-floating-ips endpoint of nova returns a 500 (because " 'FlatManager' object has no attribute 'get_floating_ips_by_project' ")

Horizon can't e.g. launch instances when this is the case. In addition, going to the "instances & volumes" tab gives a 500 error.

It is possible to launch instances via the nova API.

I'm also opening a related bug in Nova, as I'm not sure where we can best fix this.

Here's the info from Horizon's log:

Justin: That's the bug number for this bug. Can you link to the actual Nova bug?

We'll have to see what the fix for this in Nova is to see whether we need to apply a fix on our end or not.

Sorry for stupidity... Bug #937227

I proposed a nova fix here:,5494,patchset=1

I just stub-implemented the floating ips functionality (so it won't return any floating IPs).

It looked much harder to fix in a sensible way in horizon.

When the fix lands in Nova we can mark this resolved in Horizon.
