Hey guys! Next Ubuntu and Mitaka are promising something ultra mega cool!
Look at this! --- root@mitaka-1:~# apt install neutron-openvswitch-agent Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: dpdk libdpdk0 openvswitch-common openvswitch-switch --- Xenial will brings DPDK-2.2 fully supported for 5 years! However, I am curious about the following scenarios: Will be possible to use, at the same time (same Network and Compute nodes / Host Aggregate): 1- Regular OVS bridges without DPDK for VXLAN Networks, with OVS-Firewall-Driver and; 2- OVS powered by DPDK for Provider Networks only ( without any firewall, current case anyway, due to https://bugs.launchpad.net/neutron/+bug/1531205 ). ? I have NFV Instances that are also, DPDK L2 Bridges running on KVM Guest / VirtIO, that are physically wired using Provider Networks (flat and vlans). So, for the Instance's vNICs (eth1 and eth2) that are used as a L2 bridge, I don't want any kind of ovs-firewall (I'm not affected by LP #1531205 on this case) and I want OVS+DPDK under it but, for SSH into the Instance to manage it (via its eth0), it is still using regular VXLAN with Security Groups - OVS-Firewall from now on (no need for DPDK under eth0 / VXLAN). I'm curious about this specially because the OVS Ubuntu package, makes use of Debian's Alternatives subsystem, and we need to choose one OVS (default), or another (with DPDK), via "update-alternatives", so, will be possible to select OVS with DPDK but, use regular bridges with it as well (for VXLAN networks)? If yes, how to create a VXLAN network with regular OVS and another FLAT/VLAN network with OVS+DPDK ? Thanks in advance! Best, Thiago
