[Engine-devel] Problem with detachment of host interface using ovirt-sdk

[Itzik Brown]

Hi,

I tried using ovirt-sdk against  ovirt-engine-3.0.0_0001-1.6.
I still get the same result:

10:29:26,554 WARN  [org.jboss.resteasy.core.SynchronousDispatcher] (http--0.0.0.0-8080-4) failed to execute: org.ovirt.engine.api.restapi.resource.BaseBackendResource$WebFaultException

Please advise,

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:

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



This body part will be downloaded on demand.

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 at 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>
