Hi Eric. Is this a bug?
$ nbdkit -fv random size=1023
(You can choose any size which is not a multiple of 512.)
$ qemu-img convert nbd:localhost:10809 /var/tmp/test
qemu-img: error while reading sector 0: Invalid argument
In the nbdkit debugging output:
nbdkit: random.1: error: invalid request: offset and count are out of range:
offset=0 count=1024
qemu requested bytes beyond the end of the size of the device.
Rich.
