Public bug reported:
I tried the following on VMware using the VMwareVCDriver with nova-
network:
1. Create an instance
2. Create and associate a floating IP with the instance
It failed and printed out the following messages in n-api logs:

With the switch to using FloatingIP objects, it is not longer necessary to call
_normalize_ip in nova/api/openstack/compute/contrib/floating_ips.py. The
updated code in nova/network/floating_ips.py and
nova/api/openstack/compute/contrib/floating_ips.py has logic to get the
instance associated with the floating IP, i.e. get_instance_by_floating_ip_addr.
