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

[Juan Hernandez]

Itzik, can you provide the complete python script that is generating
that fault? I will try to reproduce it in my environment.

It will be also helpful to know the exact version of ovirt-engine-sdk
that you are using. If you cloned the git repository just tell me what
is the commit.
