~RohitWould I get to know will this issue get solve in 4.1 release ?On git repository, I saw some commit in which added support to switch network type in host. but there is red cross across those changes.Hi All,I am also facing same issue (unable to change ovirtmgmt to OVS type).I tried modifying ifcfg-ovirtmgmt and ifcfg-eth0 file to support OVS and then rebooted m/c.When m/c got bootup I found that configuration made in ifcfg got overwritten by vdsm.Is their any workaround ?Thanks,On Thu, Dec 29, 2016 at 5:17 AM, Sverker Abrahamsson <sverker@abrahamsson.com> wrote:From /usr/libexec/vdsm/hooks/before_device_create/ovirt_provider_ ovn_hook (installed by ovirt-provider-ovn-driver rpm):

Hi
I first tried to set device name to dummy_0, but then ifup did not succeed in creating the device unless I first did 'ip link add dummy_0 type dummy' but then it would not suceed to establish the if on reboot.
Setting fake_nics = dummy0 would not work neither, but this works:
fake_nics = dummy*
The engine is now able to find the if and assign bridge ovirtmgmt to it.
However, I then run into the next issue when starting a VM:

This VM has a nic on ovirtbridge, which comes from the OVN provider.

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 scenario (even if it

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.

Den 2016-12-28 kl. 10:45, skrev Marcin Mirecki:
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?
I then create a bridge for use with ovirt, with a private address.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:

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.
