[Qemu-devel] [Bug 1677492] [NEW] block_set_io_throttle complaints Need exactly one of 'device' and 'id'

[dE]

Public bug reported:

All of sudden, after a qemu update, block_set_io_throttle does not work
anymore.

Full command to QEMU monitor --

(qemu) block_set_io_throttle db 0 0 0 0 0 0
Need exactly one of 'device' and 'id'

The help text still point to the same old syntax, which no longer works.

Broken in 2.8, fixed here (will be in 2.9):

commit 3f35c3b166c18043596768448e5d91b5d52f8353
Author: Eric Blake <eblake@redhat.com>
Date:   Fri Jan 20 17:03:59 2017 -0600

    hmp: fix block_set_io_throttle

    Commit 7a9877a made the 'device' parameter to BlockIOThrottle
    optional, favoring 'id' instead.  But it forgot to update the
    HMP usage to set has_device, which makes all attempts to change
    throttling via HMP fail with "Need exactly one of 'device' and 'id'"
