Hi,

We have a failure on OST/network-suite-master for several days now.
My suspicions of the cause are detailed below.
Can you have a look?

Thanks

Hi Ondra,

We have above failure on OST network-suite-4.2 [1] due to:
Fault reason is "Request syntactically incorrect.". Fault detail is "For correct usage, see: https://192.168.201.4/ovirt-engine/apidoc#services/vm/methods/preview_snapshot"

and I see in engine.log [2]:
javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"disks")

at the same time I see in model_4.2 [3] that a change was done to add the disks, but if i am not mistaken the ovirt-engine-sdk pom.xml [4] was not bumped to reflect this change.
Can you please check?

Thanks
