Hi Martin,

    Sorry for that I have not observed this patch. I made a duplicated
work about this recently. and I found this patch has not been updated
for several days, but since the QEMU have extra supported "memory-file"
and some flags/properties, this patches should be refactored. 
    Do you plan to send a new version ? If not, Can I take over them?

Thanks,
Chen
