Comment 2 for bug 1334164

That fix did get past the sa_instance_state problem, but I bumped into something new. It looks like floating_ip_update() doesn't like the SA fixed ip that's fetched here:

+ updates['fixed_ip'] = db.fixed_ip_get(context, id_)

I'm not sure what "A conflicting state is already present in the identity map" means. Is there another way to fetch the fixed ip?

Traceback:
