Note: When I configured vdsm-tool ovn-config, I passed it the IP address of
the OVN-Controller which is using the ovirtmgmt network, which is just one
of the NIC's on the nodes.
I am opening up new thread as this I feel differs a bit from my original
request. I have OVN which I believe is deployed correctly. I have noticed
that if instances get spun up on the same oVIRT node they can all talk
without issues to one another, however if one instance gets spun up on
another node even if it has the same (OVN network/subnet), it can't ping or
reach other instances in the subnet. I noticed that the OVN-Controller of
the instance that can't talk is logging:

New subject: oVIRT 4 / OVN / Communication issues of instances between nodes.
Devin,
Please not the OVN-controller is not the central part where OVN northd is running.
OVN-controllers are the OVN processes deployed on the hosts.
The correct usage of the 'vdsm-tool ovn-config'.
- the IP of the OVN-central (not to be confused with OVN-controllers, which is the part
of OVN running on the hosts)
- the local host IP to be used for tunneling to other OVN hosts
for example, if the OVN-central IP should be 10.10.10.1, and the IP of the local host used
for tunneling: 10.10.10.101:
vdsm-tool ovn-config 10.10.10.1 10.10.10.101
Looking at the output of 'ovs-vsctl' the tunnels have been created.
The OVN log saying 'dropping duplicate flow' is worrying, let me forward this to
the OVN team to take a look at it.

Marcin,
For OVN to work properly does the port that the traffic flows over need to
be a bridge, or OVS port? Right now it's just going over the ovirtmgmt
network which is just a standard port. I know like in Neutron you have to
configure (br-ex) and then it would need to be using the OVS protocol, and
then all the nodes would need to be an OVS port. I presume OVN tries to
simplify this setup?
I also seen that there is (openvswitch-ovn-vtep), would this need to be
configured in any way?

ip link - the result should include a link called genev_sys_ ...
I noticed that on my hosts I don't see any links with name: genev_sys_ ??
Could this be a problem?

Marcin,
For OVN to work properly does the port that the traffic flows over need to
be a bridge, or OVS port? Right now it's just going over the ovirtmgmt
network which is just a standard port. I know like in Neutron you have to
configure (br-ex) and then it would need to be using the OVS protocol, and
then all the nodes would need to be an OVS port. I presume OVN tries to
simplify this setup?
I also seen that there is (openvswitch-ovn-vtep), would this need to be
configured in any way?

Hi Devin,
What distribution and kernel version are you using?
One thing you could check is whether the vport_geneve kernel module
is being loaded, e.g. you should see something like:
$ lsmod | grep vport
vport_geneve 12560 1
openvswitch 246755 5 vport_geneve
If vport_geneve is not loaded, you could "sudo modprobe vport_geneve"
to make sure it's available and can be loaded.
The first 100 lines or so of ovs-vswitchd.log might have some useful
information about where things are going wrong.
It does sound as though there is some issue with geneve tunnels,
which would certainly explain issues with inter-node traffic.
Regards,
Lance

Lance,
I found some interesting logs, we have (3) oVIRT nodes.
We are running:
CentOS Linux release 7.2.1511 (Core)
Linux hostname 3.10.0-327.36.3.el7.x86_64 #1 SMP Mon Oct 24 16:09:20 UTC
2016 x86_64 x86_64 x86_64 GNU/Linux
What is interesting now is my 2nd node now won't hand out DHCP any more,
however it does have a strange "tunnel" error message on node2 also, see
below. What is bizarre node1 nor node3 show that bizarre tunnel message?
[ovirt-node1]
[root@ovirt-node1 ~]# lsmod | grep vport
vport_geneve 12815 1
geneve 13381 1 vport_geneve
openvswitch 84535 1 vport_geneve

Hi Devin,
What distribution and kernel version are you using?
One thing you could check is whether the vport_geneve kernel module
is being loaded, e.g. you should see something like:
$ lsmod | grep vport
vport_geneve 12560 1
openvswitch 246755 5 vport_geneve
If vport_geneve is not loaded, you could "sudo modprobe vport_geneve"
to make sure it's available and can be loaded.
The first 100 lines or so of ovs-vswitchd.log might have some useful
information about where things are going wrong.
It does sound as though there is some issue with geneve tunnels,
which would certainly explain issues with inter-node traffic.
Regards,
Lance

Lance,
I found some interesting logs, we have (3) oVIRT nodes.
We are running:
CentOS Linux release 7.2.1511 (Core)
Linux hostname 3.10.0-327.36.3.el7.x86_64 #1 SMP Mon Oct 24 16:09:20 UTC

This (generally unintelligible message usually indicates that the kernel
openvswitch module doesn't support conntrack.

OK, "Datapath does not support ct_*" confirms that the kernel openvswitch
module doesn't support the conntrack features needed by OVN.
Most likely the loaded module is the stock CentOS one, you can build
the out-of-tree kernel module RPM from the same source tree where you
built the other OVS/OVN RPMs via:
make rpm-fedora-kmod
This should leave an RPM named something like:
openvswitch-kmod-2.6.90-1.el7.centos.x86_64.rpm
Install that and reboot and things should be working better.
Regards,
Lance
Your help is greatly appreciated!

Lance,
Well I installed the new kernel module and it cleared up a lot of the
errors I was seeing in the log, but what I notice is that I still can't
ping instances between hosts. I'm starting to wonder am I missing
something fundamental here? I don't see anything in the ovs-vswitchd.log to
show tunnel?
I do show in the kernel log on reload of the module:
[1056295.308707] openvswitch: module verification failed: signature and/or

OK, "Datapath does not support ct_*" confirms that the kernel openvswitch
module doesn't support the conntrack features needed by OVN.
Most likely the loaded module is the stock CentOS one, you can build
the out-of-tree kernel module RPM from the same source tree where you
built the other OVS/OVN RPMs via:
make rpm-fedora-kmod
This should leave an RPM named something like:
openvswitch-kmod-2.6.90-1.el7.centos.x86_64.rpm
Install that and reboot and things should be working better.

Lance,
Well I installed the new kernel module and it cleared up a lot of the
errors I was seeing in the log, but what I notice is that I still can't
ping instances between hosts. I'm starting to wonder am I missing
something fundamental here? I don't see anything in the ovs-vswitchd.log to
show tunnel?
Hi Devin,
OK, some small progress then. I think the best next step would be to look
at the current state of your system. Could you send the output of the
following commands?
On the nodes running ovn-controller:
ps -fwwC ovn-controller
ovs-vsctl show
ovs-dpctl show -s
ovs-ofctl -O OpenFlow13 dump-flows br-int
On the node running ovn-northd:
ovn-sbctl show
ovn-sbctl dump-flows
Thanks,
Lance

Lance,
I have attached the output of each into different files. I really
appreciate your help very much.

Lance,
I have attached the output of each into different files. I really
appreciate your help very much.
Based on asking around about the "dropping duplicate flow:", it's a
known issue that is harmless (other than the noise). I'll try
to find out if someone has a fix in the works.
It seems your node1 has no port bindings... is that expected?
From the counters, it looks like node2 and node3 have attempted
to send packets on the geneve tunnels, but neither has received
anything.
Could you verify that node2 and node3 have connectivity on the
IPs used for the tunnels, e.g. by trying to ping 172.10.10.75
and 172.10.10.73 from node2?
If that works, the issue might be iptables rules dropping
geneve packets, the simplest way around that would be to
"systemctl stop firewalld" if that's running (ok for a lab
environment anyway).
Thanks,
Lance

Lance,
It appears that firewalld was my issue, can you just confirm with me what
Ports should be opened for Geneve and OVN to work properly?

Based on asking around about the "dropping duplicate flow:", it's a
known issue that is harmless (other than the noise). I'll try
to find out if someone has a fix in the works.
It seems your node1 has no port bindings... is that expected?
From the counters, it looks like node2 and node3 have attempted
to send packets on the geneve tunnels, but neither has received
anything.
Could you verify that node2 and node3 have connectivity on the
IPs used for the tunnels, e.g. by trying to ping 172.10.10.75
and 172.10.10.73 from node2?
If that works, the issue might be iptables rules dropping
geneve packets, the simplest way around that would be to
"systemctl stop firewalld" if that's running (ok for a lab
environment anyway).
Thanks,
Lance

Hi Devin,
That's good to hear!
On the ovn-northd node, you need TCP ports 6641 and 6642 open (as mentioned in
Marcin's blog), on the ovn-controller nodes you need to allow packets with
destination UDP port 6081 (Geneve tunnels).

Lance,
We have a problem with communication between different hosts in OVN.
Could you please take a look at the log below?
The part with "dropping duplicate flow" sounds worrying.
Thanks,
Marcin

Note: When I configured vdsm-tool ovn-config, I passed it the IP address of
the OVN-Controller which is using the ovirtmgmt network, which is just one
of the NIC's on the nodes.
I am opening up new thread as this I feel differs a bit from my original
request. I have OVN which I believe is deployed correctly. I have noticed
that if instances get spun up on the same oVIRT node they can all talk
without issues to one another, however if one instance gets spun up on
another node even if it has the same (OVN network/subnet), it can't ping or
reach other instances in the subnet. I noticed that the OVN-Controller of
the instance that can't talk is logging:

From the OVN-Controller:

Do I need to do something special in order to allow communication between
nodes of instances on same OVN network?
