Hi Forum
I would like to replace the linux bridge installed with libvirt with a
openvswitch bridge, so I can learn about openvswitch.
I cannot get the VM to communicate with the bridge I create with openvswitch.
Here is what I did on a vanilla Ubutnu 17.10 Server X86_64 installation.
Installing
Hi everyone,
We experienced an openvswitch issue on our redhat openstack
infrastructure. Since it's rather exotic, and we haven't been
able to reproduce it, I'm sharing it here.
After some high CPU, openvswitch got into some sort of
device-port-contention looking like this:

Hi Gerhard/all,
We also saw this on RHEL 7.4 using OVS 2.7.2.
It didn't stop until we restarted openvswitch service as well.
Log messages showed the following:
2017-11-07T20:56:00.688Z|986468|bridge|INFO|bridge br-int: added interface
ha-a1a195a9-c9 on port 12043
2017-11-07T20:56:00.735Z|986469|b
Since an update of ovn/openvswitch the slave switches can't connect to
the master database. In the ovsdb-server-sb.log I get messages like the
below:

Indeed, that was the issue:
[root@h2 ~]# ovn-sbctl get-connection
read-write pssl:6642
[root@h2 ~]# ovn-sbctl set-connection ptcp:6642
[root@h2 ~]# ovn-sbctl get-connection
read-write ptcp:6642
After changing that the connection was established.
Thank you

OVS doesn't have queues of its own. If you want to control queuing for
the Linux kernel datapath, and the existing Linux network queuing
disciplines don't do what you want, you should create a new Linux
network queuing discipline that does what you want.

If you use the kernel module that comes with OVS repo, it will work. If you
use the kernel module that comes by default with linux kernel, it won't.
You can look at ovs-vswitchd.lo
Sorry if this has been asked before.
There's few examples on how to use jsonrpc to insert an interface, for
example.
For us, newbies, examples are extremely valuable, more than a thousand

hi,
I new to the OVS connection tracking, I am trying to add the following flow
and get the ERROR
#ovs-ofctl add-flow s1 "in_port=1, actions=ct(commit,
nat(src=10.0.0.240-10.0.0.254))"
#ovs-ofctl: actions are invalid with specified match
(OFPBAC_MATCH_INCONSISTENT)
I am not able to figure out wh
Looks, like I was giving a wrong command, I corrected it now and did the
following:
#ovs-ofctl add-flow s1 "ct_state=+new,icmp,in_port=1, actions=ct(commit,
zone=1, nat(src=10.0.0.240))"
I get the OFPT_ERROR, which means the cmd is not supported, so I guess the
OVS which I am using doesnt support
For the unsuccessful case, did you check the database log? It may
contain a log message pointing to the mistake.

"nat was introduced in Open vSwitch 2.6. The first datapath that
implements ct nat support is the one that ships with Linux 4.6."
I think you might want to install openvswitch-datapath-dkms package
after ovs 2.6, or use upstream openvswitch kernel mo
hi, I'm using ovs2.8 with dpdk-17052, and the 'NetXtreme II BCM57810 10 Gigabit

There comes the error, while I try to bind the NIC using igb_uio.

Thanks Guru.
Yes, I have replaced the upstream kernel with OVS kernel module repo 2.8.1,
I mean from [1] which add openvswitch: nat support in linux datapath seems
also
including below changes and those doesn't included in the OVS kernel
module, so I am concerning is it enough for just replace ker
Hi folks,
I am a bit confused of the OVN logical router port arp flow process if
arping it from external side.
When I am tracing the logical router port arp, it always seems there would
be no response from the flow procedure, however, I do can get the arp
response and reach it.

Is there a specific reason as to why you would want to use this version of
DPDK? I have never had to check permission.
Also, igb is mainly for Intel NICs. You are using a Broadcom NIC -
http://dpdk.org/doc/guides/nics/bnxt.html for driver info. I think what
you have is a misconfiguration.

I just want to use ovs-2.8 for userspace connection-track, and I choose the
latest LST DPDK 1705.
But, you mean theres is something like broadcom-uio.ko when using broadcom NIC?
I just have changed the config/common_base:
CONFIG_RTE_LIBRTE_BNX2X_PMD=y
CONFIG_RTE_LIBRTE_BNX2X_DEBUG=y
