Hi all. I searched but the information I got about Neutron and Xen are quite rare. In the official installation document and a great guide https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst (here), only KVM is used.

In my deployment, I tried to added a network br-int in XenServer, and put all VM on that network. Also, the compute node is also plugged into that network. In computer node, I can read traffic sent by VM by

tcpdump -i eth3 # eth3 is the interface in Computer Node which connected to br-int network in XenServer

Based on the guides above, in computer node, I created two bridges: br-int and br-tun, and get oepnvswitch-agent configured. I tried to plug eth3 as a port in br-int of computer node, and run

tcpdump -i br-int

but no data captured. Although I do captured data sent by VM at eth3 of computer node, but br-int give me nothing.

Why this happened? Is there any better way to setup Neutron on Xen install?

Thanks.

P.S.: I found https://bugs.launchpad.net/neutron/+bug/1268955 (some articles) mentioned that a dom0 agent is required for this installation to work. But no detail found.

I am beggining with OpenStack in a Xen environment and my next step is configure Neutron too. I am still not having a clue but I thing that we should find the way to connect with xenbr0, xenbr1, etc. if I find any info, I will update you.

Regards

Please see http://blogs.citrix.com/2013/06/14/op... for some details on how to configure Neutron (formally known as Quantum) for XenServer.

In particular https://raw.githubusercontent.com/mat... might be a useful deployment diagram

I am also trying to find some official documentation add one compute node as xen-server into openstack juno version. I have already installed openstack with neutron as the networking but I am only using KVM now. In the administration documentation of openstack, it says many neutron plungis only support KVM. http://docs.openstack.org/admin-guide-cloud/content/section_plugin-arch.html (http://docs.openstack.org/admin-guide...)
