Guys,<br>
<br>
This problem is kind of a "deal breaker"... I was counting on OpenStack<br>
Havana (and with Ubuntu) for my first public cloud that I'm (was) about<br>
to announce / launch but, this problem changed everything.<br>
<br>
I can not put Havana with Ubuntu LTS into production because of this<br>
network issue. This is a very serious problem for me... Since all sites,<br>
or even ssh connections, that pass through the "Floating IPs" entering<br>
into the tenant's subnets, are very slow and, all the connections<br>
freezes for seconds, every minute.<br>
<br>
Again, I'm seeing that there is no way to put Havana into production<br></div>
(using Per-Tenant Routers with Private Networks), _because the Network<br>
Node is broken_. At least when with Ubuntu... I'll try it with Debian 7,<div class="im"><br>
or CentOS (I don't like it), just to see if the problem persist but, I<br>
prefer Ubuntu distro since Warty Warthog... :-/<br>
<br>
So, what is being done to fix it? I already tried everything I could,<br>
without any kind of success...<br>
<br>
Also, I followed this doc (to triple * triple re-check my env):<br>
<a href="http://docs.openstack.org/havana/install-guide/install/apt/content/section_networking-routers-with-private-networks.html" target="_blank">http://docs.openstack.org/<u></u>havana/install-guide/install/<u></u>apt/content/section_<u></u>networking-routers-with-<u></u>private-networks.html</a> but,<br>
it does not work as expected.<br>
</div></blockquote>
<br>
I'd just like to point out that it is indeed possible to achieve good network performance (bi-directional) with Ubuntu 12.04, OVS 1.11, and OpenStack Grizzly with Neutron and GRE tunnels. We've deployed two zones with it and after upgrading to OVS 1.11, we are seeing pretty good performance.<br>
<br>
We use the OpenStack Chef cookbooks to configure Neutron:<br>
<br>
<a href="https://github.com/stackforge/cookbook-openstack-network" target="_blank">https://github.com/stackforge/<u></u>cookbook-openstack-network</a><br>
<br>
You may want to go through the above cookbook and check the default settings that are in the attributes and written to the configuration file templates.<br>
<br>
I don't know of anything that changed between Grizzly and Havana that would have had an impact on network performance, but perhaps someone from the Neutron dev community could chime in here and write if there's been anything added in the Havana timeframe that may affect network performance...<br>
<br>
Best,<br>
