Currently, no. Creating a new request operation type that allows the front end to pass through ioctls would be useful, but it ends up being rather Linux specific. Further, for security reasons the backend is going to need to be able to decode the ioctl and decide whether its safe to issue or not. It would be better to have a 'wire protocol' for this. A mechanism for passing scsi commands through would be better, but even then there are a bunch of vendor-specific ones its not entirely easy to tell whether they should be allowed by a guest or not. I suspect we need to draw up a list of what "ioctls" should be allowed. What one do you want to perform?
