Greetings!<br>
<br>
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.<br>
<br>
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?<br>
<br>
I'm puzzled by the statement that "

<a id="d9e8847" class="indexterm">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.
</a>I have no particular reason to prefer Neutron, but I'd like to
avoid betting on a horse right before it's put down :)<br>
<br>
Thanks!<br>
