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.

Hello,

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

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.
