The Hyper-V agent raises:

The issue does not affect functionality, but it creates a lot of noise in the logs since the error is logged at each iteration.

Could you provide more detail information? Which method was requested when this error occurs?
Let me mark this Incomplete.

If Hyper-V team is already working on it, it is nice.

debug level log is http://paste.openstack.org/show/97957/

ML2 RPC port_update method causes the error message.
ML2 RPC base version is wrongly bumped to 1.1 and it breaks hyper-v agent with ML2 plugin.
It is not an intended behavior.

Ideally ML2 RPC API base version should be reverted to 1.0, but it affects several agents,
so bumping API version in hyper-v agent sounds reasonable approach.

    Fixes Hyper-V issue due to ML2 RPC versioning

    The ML2 RPC version 1.1 breaks the hyper-v agent and
    consequentially the RPC version in the Hyper-V agent needs
    to be set to 1.1 to match the ML2 RPC base API version.
