I can ssh into my VM via its eth0 (public), my VM can talk with other VMs via its eth1 (private), and my virtualized DPDK-App runs fine on top of two VirtIO vhostuser NIC (eth2 and eth3).</font><br><br><font size="4"> Now, time to do this via OpenStack! But, it doesn't work like this, let me try to explain...</font><br><br><font size="4"> On OpenStack, without OVS+DPDK, my KVM Guest also have 4 vNIC, first two (eth0 and eth1), are VXLAN networks (using the OpenvSwitch Agent), and the latest two (eth2 and eth3), are Provider Networks (also using the OpenvSwitch Agent).</font><br><br><font size="4"> So, here comes the problem with OVS and DPDK...</font><br><br><font size="4"> I've configured Neutron OVS Agent like this: </font><a href="http://docs.openstack.org/developer/neutron/devref/ovs_vhostuser.html"><u><font size="4" color="#0000FF">http://docs.openstack.org/developer/neutron/devref/ovs_vhostuser.html</font></u></a><br><br><font size="4"> My intention, is to use the OVS+DPDK _only_ for the Provider Networks, but, when I started my Instance, all the 4 vNIC are being tied to the OVS+DPDK bridges, which is clearly, not what I've configured on my Neutron Agents.</font><br><br><font size="4"> So, I'm thinking here, how can I do this?</font><br><br><font size="4"> Regular "OVS Regular" bridges for VXLAN networks, and "OVS DPDPK" bridges for Provider Networks?</font><br><br><font size="4"> OR, how to use OVS+DPDK for VXLAN networks? If this is possible, does it still supports the ovs-firewall-driver?</font><br><br><font size="4"> Another workaround, that I'm thinking here, would be to launch 2 OVS Agents on my Compute Nodes, one for OVS and VXLAN, and another only for OVS+DPDK... Or, maybe, for VXLAN, I can go back to Linux Bridges...</font><br><br><font size="4"> I've read that RedHat don't recommend DPDK for VXLAN networks but, I'm using Newton on Ubuntu, so, things might be different, specially because Ubuntu have native support for a very recent DPDK version, for free, thoughts?</font><br><br><font size="4"> I appreciate any comments!</font><br><br><font size="4">Thanks!</font><br><font size="4">Thiago</font><tt>_______________________________________________<br>Mailing list: </tt><tt><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack</a></tt><tt><br>Post to : openstack@lists.openstack.org<br>Unsubscribe : </tt><tt><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack</a></tt><tt><br></tt><br><br><BR>
