Hello,

When I launch a VM instance, I see the following message regarding floating IP in nova-network.log:

2012-11-18 15:50:29 DEBUG nova.network.manager [req-f2b4df1f-6c29-48dc-991b-93fb5eb29d08 ce016bb05df949ebbafcc7c165359d7c ce1e819636744dc680fa5515f6475e87] [instance: 4e80964e-5bd1-4df4-a517-223c79d55517] floating IP allocation for instance |%s| from (pid=1375) allocate_for_instance /usr/lib/python2.7/dist-packages/nova/network/manager.py:315

I did not configure nova to assign floating IP to VMs.  Can someone please help me understand why nova-network is assigning floating IP.

Thank you,
Ahmed.
