In spite of this flag,  I see WRITE_SAME_16 being issued when I format a device 
bigger than 2 TB;
I tried both xfs and ext4. Windows hosts currently do not handle unsupported 
commands correctly -
The information returned is not sufficient to effect recovery in the Linux 
guest. While this may be addressed in
future hosts, this patch fixes the problem.
