[Qemu-devel] Question about open() in qemu

[morgenlette madeBy]

Hello

I am studnet studying QEMU.

I have a question open in QEMU.

In  function handle_aiocb_rw_linear() in block/raw-posix.c,

i tried to open my device driver(mydev).

this driver was confirmed safe operation by test program.

But in qemu, this driver was not opened returning -1.

errno is 1. 1 means 'Operation not permitted'

QEMU is not supporting open()???
