The XCP PV driver does not like the SCSI Op codes for RESERVE/RELEASE 
and possibly RESET.

I am trying to install Microsoft Failover Clustering on a HVM with the 
XCP PV drivers installed and disk arbitration is broken.

Is there a registry setting or otherwise to enable this behavior?

Or can code be changed to return success if these opcodes are seen in 
the CDB?

I am fairly certain that this will make clustering work and serve as a 
valuable tool to play with clustered Windows configurations.
