But we have two cases to consider: - one submitted IO includes requests from multi vq(virtio-blk or virtio-scsi maybe), and each vq has to notify guest - one submitted IO includes requests from multi bs for scsi device The 2nd case should be easy to handle, but I am a bit headache for the 1st case.
You can just have one bottom half per virtqueue. :) Paolo
