Hi,
I am trying to setup OVS network using ovirt and found guide as shown below:
https://www.ovirt.org/networking/ovs/
Then, I tried to explore "vNic Profile" in sdk but not found any ovs
profile in types.py.
Can anyone help me how to setup ovs using python sdk ?
I am using ovirtsdk4 (4.0 version).
Thanks,
~Rohit

Note that it isn't complete, and that I didn't test if the OVS network
does work. But at least the creation of the network and the modification
of the VNIC profile does work.
I am suggesting to add this to the collection of examples of the SDK:
Add example of how to create OVS network
https://gerrit.ovirt.org/68825
You may want to review it.

Hi,
Thanks for providing script it is working fine.
But it not complete, would you help me to complete step 2 ?
https://www.ovirt.org/networking/ovs/
Setup network
In the oVirt UI open the 'Setup Host Networks' dialog. Proceed to editing a
desired logical network's properties. Among them you will find 'ovs', set
it to 'true' or '1' to mark is as a OVS Network.
And have one doubt.
Why we have to set ovs property two time ?
Thanks,
~Rohit

Hi,
I found a way to update property in setup network as shown below
# Get the reference to the hosts service:
hosts_service = connection.system_service().hosts_service()
myhost = hosts_service.list(search='name=myhost')[0]
myhost_service = hosts_service.host_service(myhost.id)
mynet_attached_services = myhost_service.network_attachments_service()
for mynet_attachment in mynet_attached_services.list():
if mynet_attachment.network.name == "mynet":
print "Found : %s"%(mynet_attachment.network.name)
mynet_attached_services.attachment_service(mynet_attachment.id).update(
attachment=types.NetworkAttachment(
properties=[types.Property("ovs","1")]
) )
else:
print "Not Found : %s"%(mynet_attachment.network.name)
Please find below ovs output.

But ovirt is showing me "out-of-sync" message.
*Can someone explain me why it shown as out-of-sync ?*

You should not use the OVS hook or native implementation.
We don't feel this feature is ready and we stopped its development recently.
You should look at the OVN implementation, there is a deep dive planned for
this soon, please look it up.
