[Qemu-devel] qemu and own disk driver writing questions

[Vasiliy Tolstov]

Hi! If i want to develop some sort of qemu network block driver to own
storage. I can write qemu driver or tcmu / scst userspace driver and
attach to qemu block device (i'm use linux)
So in theory what path have minimal overhead in case of memory copy
and performance?
Where i can find some info how qemu works with data that needs to be
written or readed from block device passed to vm?
Thanks.
