[ovirt-users] Issue adding Network to host with Python SDK

I am having issue with adding network to host nic with python SDK. It works just fine using the portal GUI. I have the following: bond0 that is setup as mode 4 bond0.120 that is attached to ovirtmgmt network bond0.96 that I am trying to attach a new installed network called External. Below is a code snippet of what I am trying to do: hosts_service = connection.system_service().hosts_service() host = hosts_service.list(search='name=%s' % HOSTNAME)[0] host_service = hosts_service.host_service(host.id) hostnics_service = hosts_service.host_service(host.id).nics_service() n = None for n in hostnics_service.list(): if n.name == 'bond0.96': n_id = n.id print("n is %s" % n_id) system_service = connection.system_service() networks_service = connection.system_service().networks_service() network = networks_service.list( search='name=External and datacenter=%s-local' % HOSTNAME) [0] print ("Network name is %s" % network.name) print ("Network id is %s" % network.id) net_attachments_service = host_service.network_attachments_service() net_attachment = net_attachments_service.add( types.NetworkAttachment( network=types.Network(id=network.id), host_nic=types.HostNic(name='bond0.96') ), ), I will end up with an error of File "./add_host_py", line 193, in Add_External_network host_nic=types.HostNic(name='bond0.96') File "/usr/lib64/python2.7/site-packages/ovirtsdk4/services.py", line 15441, in add self._check_fault(response) File "/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py", line 98, in _check_fault Service._raise_error(response, fault) File "/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py", line 71, in _raise_error raise Error(msg) ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Cannot setup Networks. The attachment of network 'External' references vlan device 'bond0.96'. Network attachment cannot reference vlan device.]". HTTP response code is 400. Can someone guide me on what I am doing wrong or not understanding with the NetworkAttachment Service? Thanks Don
