[Bug 1233433] [NEW] hv: util: Fix a bug in version negotiation code for util services

 

Public bug reported:

The current code picked the highest version advertised by the host. WS2012 R2
 has implemented a protocol version for KVP that is not compatible with prior
 protocol versions of KVP. Fix the bug in the current code by explicitly specifying
 the protocol version that the guest can support.

More information and the entire patch is available here:

Thanks,
Abhishek
