Doing this may not be a good thing based on the kernel rules I have understood until now. Maybe Greg and Wolfram can clarify on this. We are waiting here for an external entity (Host kernel) or a firmware that uses virtio for transport. If the other side is hacked, it can make the kernel hang here for ever. I thought that is something that the kernel should never do.
I'm also worried about this. We may be able to solve it by setting a big timeout value in the driver.
