Hi Vish,
I do not have auto_assign_floating_ip set. So, I can safely assume
nova-network is assigning fixed-IP, right?
Sorry to impose, but do you have a few minutes to help me understand by I am
getting a RPC message timeout issue which is prohibiting me from launching a
VM. I looked through the logs extensively, but I can't figure out, who the RPC
msg is destine for, and why no response.

Subject: Re: [Openstack] Floating IP vs. Fixed IP in nova-network
That is a confusing log message. That log is from the allocation code in the
floating ip mixin class. It is not actually allocating a floating ip unless you
have auto_assign_floating_ip set to True.

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.
