Re: [ovirt-users] How to setup OVS using python SDK ?

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. # ovs-vsctl show Bridge "vdsmbr_tJ9jxY5o" Port "em2" Interface "em2" Port "vdsmbr_tJ9jxY5o" Interface "vdsmbr_tJ9jxY5o" type: internal Port mynet Interface mynet type: internal ovs_version: "2.4.0" But ovirt is showing me "out-of-sync" message. *Can someone explain me why it shown as out-of-sync ?* *How ovirt determine sync on logical network ?* Thanks, ~Rohit On Mon, Dec 26, 2016 at 7:04 PM, TranceWorldLogic . < tranceworldlogic(a)gmail.com&gt; wrote: > 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.
