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.
