Thanks, i'm try to test this patch series and get error:

Block format 'raw' used by device 'drive-scsi0-0-0-0' doesn't support
the option 'detect_zeros'
my relevant libvirt xml:

<alias name='scsi-disk0'/>
<target dev='sda' bus='scsi'/>
<address type='drive' controller='0' bus='0' unit='0'/>
</disk>
Also my help message for qemu (2.5.0-rc3) does not have
"detect_zeroes", but "detect-zeroes", not _ but -
