Re: [ovs-discuss] Cannot Install Open vSwitch with DKDP
One more question. I need to use metering feature of ovs. Do I need to add interfaces to VIFO for that? I am asking this because adding interfaces to VIFO gave errors.

Please help. Hi, this is a normal behavior on OVS 2.9.x since "dpdk_initialized" support was added in 2.10 (https://github.com/openvswitch/ovs/commit/3e52fa5). So you can update to OVS 2.10(.1) or you can look for dpdk entries on ovs-vswitchd.log ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss

Please help. I believe the docs are not up to date. I was struggling with this too so I would like to suggest you to: - turn the DEBUG on for dpdk related parts of OvS: ovs-appctl vlog/list <- to get the names of modules ovs-appctl vlog/set ...:dbg <- to set debug (e.g. dpdk:file:dbg and netdef_dpdk:file:dbg) I usually turn on file:dbg on all dpdk related modules (that you get from the list) and 'tail -f' ovs-vswitchd.log to see what is going on. You should see something like: 2018-11-23T11:18:02.186Z|00019|dpdk|INFO|DPDK Enabled - initialized when DPDK gets initialized (this is INFO level so you don't have to switch to debug - but I suggest it anyway when you are starting with DPDK).

[ovs-discuss] Cannot Install Open vSwitch with DKDP
Hi. I Have installed Open vSwitch 2.9.4 with DPDK 17.11.4 on Ubuntu 14.04.5

dpdk_initialized gives ovs-vsctl: Open_vSwitch does not contain a column
whose name matches "dpdk_initialized" error. Please help.
