Description of problem:

one of the community members just reported the following where practically, connectStorageServer fails as engine send NFS version as str while vdsm expects int.

I just did a clean install of ovirt version 3.1 on CentOS 6.2 (dreyou build @ http://www.dreyou.org/ovirt/). When I attempt to add storage (Data/NFS), the web GUI hangs and the storage is not added. The engine log reports:

Class Name: org.ovirt.engine.core.vdsbroker.vdsbroker.ServerConnectionStatusReturnForXmlRpc
mStatusList                   Null
mStatus                       Class Name: org.ovirt.engine.core.vdsbroker.vdsbroker.StatusForXmlRpc
mCode                         451
mMessage                      Error storage server connection: ("domType=1, spUUID=00000000-0000-0000-0000-000000000000, conList=[{'port': '', 'connection': 'cmcd-db-vip.in.hwlab:/vmstore', 'iqn': '', 'portal': '', 'user': '', 'protocol_version': '3', 'password': '******', 'id': '500d06d3-00f7-4d8f-b42b-eabd6a394be7'}]",)

The vdsm.log on the host I'm using (also CentOS 6.2, vdsm-4.9.6-0.274.git937a4b7) says:

Thread-3810::ERROR::2012-06-12 14:58:19,879::task::853::TaskManager.Task::(_setError) Task=`c514ffd1-2777-44ae-9b77-06a9fb51f41e`::Unexpected error

Managed to reproduce latest engine-core.
