The OVN provider creates the port when you add the port in the engine UI,
it is then plugged into the ovs bridge by the VIF driver.

Port 92f6d3c8-68b3-4986-9c09-60bee04644b5 is for the new VM which is
started on h1, but it is not assigned to that chassis. The reason is
that on h1 the port on br-int is created like this:
ovs-vsctl --timeout=5 -- --if-exists del-port vnet0 -- add-port br-int
vnet0 -- set Interface vnet0
"external-ids:attached-mac=\"00:1a:4a:16:01:52\"" -- set Interface vnet0

"external-ids:vm-id=\"4d0c134a-11a0-40f4-b2fb-c13c17c7251c\"" -- set
Interface vnet0 external-ids:iface-status=active
I.e. the extrernal id of interface is wrong. When I manually change to
the right id like this the port works fine:
ovs-vsctl --timeout=5 -- --if-exists del-port vnet0 -- add-port br-int
vnet0 -- set Interface vnet0
"external-ids:attached-mac=\"00:1a:4a:16:01:52\"" -- set Interface vnet0

Getting back to the original issue with Ovirt, I've now added the
second host h1 to ovirt-engine. Had to do the same as with h2 to
create a dummy ovirtmgmt network but configured access via the public
IP. My firewall settings was replaced with iptables config and
vdsm.conf was overwritten when engine was set up, so those had to be
manually restored. It would be preferable if it would be possible to
configure ovirt-engine that it does not "own" the host and instead
comply with the settings it has instead of enforcing it's own view..
Apart from that it seems the second host works, although I need to
resolve the traffic issue over the OVS tunnel.

dots, which is not trivial as it is complex. Some insights reached:
First step is the OVN database, installed by openvswitch-ovn-central,
which I currently have running on h2 host. The 'ovn-nbctl' and
'ovn-sbctl' commands are only possible to execute on a database node.
Two ip's are given to 'vdsm-tool ovn-config <ip to database> <tunnel
ip>' as arguments, where <ip to database> is how this OVN node
reaches the database and <tunnel ip> is the ip to which other OVN
nodes sets up a tunnel to this node. I.e. it is not for creating a
tunnel to the database which I thought first from the description in
blog post.
The tunnel between OVN nodes is of type geneve which is a UDP based
protocol but I have not been able to find anywhere which port is used
so that I can open it in firewalld. I have added OVN on another host,
called h1, and connected it to the db. I see there is traffic to the
db port, but I don't see any geneve traffic between the nodes.
Ovirt is now able to create it's vnet0 interface on the br-int ovs
bridge, but then I run into the next issue. How do I create a
connection from the logical switch to the physical host? I need that
to a) get a connection out to the internet through a masqueraded if
or ipv6 and b) be able to run a dhcp server to give ip's to the VM's.

1. No, I did not want to put the ovirtmgmt bridge on my physical
nic as
it always messed up the network config making the host unreachable. I
have put a ovs bridge on this nic which I will use to make tunnels
when
I add other hosts. Maybe br-int will be used for that instead, will
see
when I get that far.
As it is now I have a dummy if for ovirtmgmt bridge but this will
probably not work when I add other hosts as that bridge cannot connect
to the other hosts. I'm considering keeping this just as a dummy to
keep
ovirt engine satisfied while the actual communication will happen over
OVN/OVS bridges and tunnels.
2. On

there is instructions how to add an OVS bridge to OVN with |ovn-nbctl
ls-add <network name>|. If you want to use br-int then it makes
sense to
make that bridge visible in ovirt webui under networks so that it
can be
selected for VM's.
It quite doesn't make sense to me that I can select other network
for my
VM but then that setting is not used when setting up the network.

<pre wrap="">Hi,
The OVN provider does not require you to add any bridges manually.
As I understand we were dealing with two problems:
1. You only had one physical nic and wanted to put a bridge on it,
attaching the management network to the bridge. This was the
reason for
creating the bridge (the recommended setup would be to used a
separate
physical nic for the management network). This bridge has
nothing to
do with the OVN bridge.
2. OVN - you want to use OVN on this system. For this you have to
install
OVN on your hosts. This should create the br-int bridge,
which are
then used by the OVN provider. This br-int bridge must be
configured
to connect to other hosts using the geneve tunnels.
In both cases the systems will not be aware of any bridges you
create.
They need a nic (be it physical or virtual) to connect to other
system.
Usually this is the physical nic. In your case you decided to put
a bridge
on the physical nic, and give oVirt a virtual nic attached to this
bridge.
This works, but keep in mind that the bridge you have introduced
is outside
of oVirt's (and OVN) control (and as such is not supported).

<pre wrap="">I am not quite sure I understand.
The external provider (OVN provider to be specific), does not add any
bridges
to the system. It is using the br-int bridge created by OVN. The
networks
created by the OVN provider are purely logical entities,
implemented using
the OVN br-int bridge.

<pre wrap="">Sverker,
br-int is the integration bridge created by default in OVN. This
is the
bridge we use for the OVN provider. As OVN is required to be
installed,
we assume that this bridge is present.
Using any other ovs bridge is not supported, and will require
custom code
changes (such as the ones you created).
The proper setup in your case would probably be to create br-int
and
connect
this to your ovirtbridge, although I don't know the details of
your env,
so
this is just my best guess.

Even better, if the value is not hardcoded then the configured

used. Might be that I'm missunderstanding something but this is

we can
put to the side for now.
It is not clear for me why the port is added on br-int
instead of the
bridge I've assigned to the VM, which is ovirtbridge??

The tunnels are created to connect multiple OVN controllers.
If there is only one, there is no need for the tunnels, so
none
will be created, this is the correct behavior.
Does the problem still occur after setting configuring the

Hi
The rpm packages you listed in the other mail are
installed but I
had
not run vdsm-tool ovn-config to create tunnel as the OVN
controller
is
on the same host.
[root@h2 ~]# rpm -q openvswitch-ovn-common
openvswitch-ovn-common-2.6.90-1.el7.centos.x86_64
[root@h2 ~]# rpm -q openvswitch-ovn-host
openvswitch-ovn-host-2.6.90-1.el7.centos.x86_64
[root@h2 ~]# rpm -q python-openvswitch
python-openvswitch-2.6.90-1.el7.centos.noarch
After removing my manually created br-int and run
vdsm-tool ovn-config 127.0.0.1 172.27.1.1
then I have the br-int but 'ip link show' does not show
any link
'genev_sys_' nor does 'ovs-vsctl show' any port for ovn.
I assume
these
are when there is an actual tunnel?

<pre wrap="">Hi,
Can you please do: "sudo ovsdb-client dump"
on the host and send me the output?
Have you configured the ovn controller to connect to the
OVN north? You can do it using "vdsm-tool ovn-config" or
using the OVN tools directly.
Please check

Also please note that the OVN provider is completely

from the neutron-openvswitch plugin. Please don't mix
the two.

Hi,
br-int is the OVN integration bridge, it should have been
created
when installing OVN. I assume you have the following
packages
installed
on the host:
openvswitch-ovn-common
openvswitch-ovn-host
python-openvswitch
Please give me some time to look at the connectivity
problem.

I first tried to set device name to dummy_0, but

Setting fake_nics = dummy0 would not work neither,

works:

The engine is now able to find the if and assign

<pre wrap="">Sverker,
Can you try adding a vnic named veth_* or dummy_*,
(or alternatively add the name of the vnic to
vdsm.config fake_nics), and setup the management
network using this vnic?
I suppose adding the vnic you use for connecting
to the engine to fake_nics should make it visible
to the engine, and you should be able to use it for
the setup.

I'm afraid that the engine is not ready for such a

Please give me some time to look for a solution.

network
Hi Marcin
Yes, that is my issue. I don't want to let
ovirt/vdsm see
eth0
nor
ovsbridge0 since as soon as it sees them it
messes up the
network
config
so that the host will be unreachable.
I have an internal OVS bridge called ovirtbridge
which
has
a port
with
IP address, but in the host network settings
that port is
not
visible.
It doesn't help to name it ovirtmgmt.
The engine is able to communicate with the host
on the ip
it has
been
given, it's just that it believes that it HAS to
have a
ovirtmgmt
network which can't be on OVN.

<pre wrap="">Hi Sverker,
The management network is mandatory on each
host. It's
used by
the
engine to communicate with the host.
Looking at your description and the exception
it looks
like it
is
missing.
The error is caused by not having any network
for the
host
(network list retrieved in
InterfaceDaoImpl.getHostNetworksByCluster -
which
gets all the networks on nics for a host from
vds_interface
table in the
DB).
Could you maybe create a virtual nic connected to
ovsbridge0 (as
I
understand you
have no physical nic available) and use this
for the
management
network?

<pre wrap="">I'm not quite sure I understand. Is this yet
another
bridge
connected to
ovsbridge0?
You could also attach the vnic for the management
network
here
if need
be.
Please keep in mind that OVN has no use in
setting up
the
management
network.
The OVN provider can only handle external
networks,
which
can
not be used
for a
management network.

Subject: [ovirt-users] Issue with OVN/OVS and
mandatory
ovirtmgmt
network
Hi
For long time I've been looking for proper
support in
ovirt for
Open
vSwitch
so I'm happy that it is moving in the right
direction.
However,
there
seems
to still be a dependency on a ovirtmgmt bridge
and I'm
unable
to move
that
to the OVN provider.
The hosting center where I rent hw instances
has a bit
special
network
setup,
so I have one physical network port with a /32
netmask
and
point-to-point
config to router. The physical port I connect
to a ovs
bridge
which has
the
public ip. Since ovirt always messes up the
network
config when
I've
tried
to let it have access to the network config
for the
physical
port, I've
set
eht0 and ovsbridge0 as hidden in vdsm.conf.
I then create a bridge for use with ovirt, with a
private
address. With
the
OVN provider I am now able to import these
into the
engine and
it looks
good. When creating a VM I can select that it
will have
a
vNic
on my OVS
bridge.
However, I can't start the VM as an exception
is thrown
in the
log:
2016-12-28 00:13:33,350 ERROR

Looking at that section of code where the
exception is
thrown,
I see
that
it
iterates over host networks to find required
networks,
which I
assume is
ovirtmgmt. In the host network setup dialog I
don't see
any
networks at
all
but it lists ovirtmgmt as required. It also
list the
OVN
networks but
these
can't be statically assigned as they are added
dynamically when
needed,
which is fine.
I believe that I either need to remove ovirtmgmt
network
or
configure
that
it
is provided by the OVN provider, but neither is
possible.
Preferably it
shouldn't be hardcoded which network is
management and
mandatory but be
possible to configure.
