Hi,
I'm using ovirt-sdk to attach and detach a network to a host's Interface.
Once the network is attached to the interface I try to detach the 
network from the interface using the following steps:
1.Detach the network from the cluster through the GUI.
2.Remove the network from the datacenter through the GUI.
3.Detach the network from the host's interface using the SDK:
nic = api.hosts.get(name=host).nics.get(name=if_name)
net = params.Network(name=net_name)
act = params.Action(network=net)
nic.detach(act)
api.hosts.get(name=host).commitnetconfig()
Then I get the error:
http://pastebin.com/3Md07huE
The same flow using the GUI works fine.
Network removal from the Datacenter is a trigger for me to run the 
detachment operation therefore I use this flow.
I use the following components:
rhevm-3.0.2_0001-2
ovirt-sdk (Using the latest from git repository)
Please advise how to proceed.
Thanks,
Itzik

Ovirt-sdk and rhevm don't comply (ovirt-sdk is based on the upstream 
version of rhevm)

Use the REST api instead:

curl -X POST user@domain:password -H "Content-Type: application/xml" 
-d@/path/to/file.xml 
https://rhevm:8843/api/hosts/{host-id}/nics/{nic-id}/detach

file.xml:

<action>
<host_nic>
<name>eth0</name>
</host_nic>
</action>
