Description Lior Vernia 2014-01-21 15:28:52 UTC
Description of problem:

When using a VDSM version < 3.4 on a host which is part of a 3.4 cluster, there is an issue with the deserialization of QoS reported by the host; even though the host should generally be non-operational in this setting, the deserialization takes place as part of the GetVdsCapabilities action, which should work without throwing exceptions even if the host is non-operational.

Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:
1. Add a host with VDSM version corresponding to < 3.4 to a 3.4 cluster.

Actual results:

ClassCastException in engine log, even if no QoS is set on the host.

Expected results:

No exceptions.
