...full amount of data to read/write. Monitoring the "inflight" numbers in the guest I've seen it go as high as 184. I'm trying to figure out if there are any limits on how high the inflight numbers can go, but I'm not having much luck. I was hopeful when I saw qemu calling virtio_add_queue() with a queue size, but the queue size was 128 which didn't match the inflight numbers I was seeing, and after changing the queue size down to 16 I still saw the number of inflight requests go up to 184 and then the guest took a kernel panic in virtqueue_add_buf(). Can someone with more k...
