Can't you simulate the same topology as the FlatDHCPManager + Floating IPs with a shared network attached to a router which is then attached to an external network?
Mmmmaybe? Floating IP support in nova-network is pretty great (allocation, assignment, release, etc.) and allows us shuffle around a small number of public IPs amongst a much larger number of instances. Your suggestion doesn't address that, does it? Short of my implementing a bunch of custom stuff on my own?

I'm about to set up a new cloud, so for the second time this year I'm facing the question of Neutron vs. nova-network. In our current setup we're using nova.network.manager.FlatDHCPManager with floating IPs. This config has been working fine, and would probably be our first choice for the new cloud as well. At this point is there any compelling reason for us to switch to Neutron? My understanding is that the Neutron flat network model still doesn't support anything similar to floating IPs, so if we move to Neutron we'll need to switch to a subnet-per-tenant model. Is that still correct? I'm puzzled by the statement that " upgrades without instance downtime will be available in the Kilo release"[1] -- surely for such a path to exist, Kilo/Neutron would need to support all the same use cases as nova-network. If that's right and Neutron is right on the verge of supporting flat-with-floating then we may just cool our jets and wait to build the new cloud until Kilo is released. I have no particular reason to prefer Neutron, but I'd like to avoid betting on a horse right before it's put down :) Thanks! -Andrew [1] http://docs.openstack.org/openstack-ops/content/nova-network-deprecation.html _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : [email protected] <mailto:[email protected]> Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack -- Kevin Benton
