    <p>Hi<br>
      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

      <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 out: <a class="moz-txt-link-freetext" href="https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/">https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/</a>
for details.

Also please note that the OVN provider is completely different
from the neutron-openvswitch plugin. Please don't mix the two.

Marcin

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.

Marcin

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

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

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?

You could also attach the vnic for the management network here

be.

Please keep in mind that OVN has no use in setting up the
management

The OVN provider can only handle external networks, which can
not be used

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.
