H A Dqemu-config.cdiff c5f3014b82adc0e8f50bf5052031503d3467bea3 Thu Oct 06 04:33:17 CDT 2016 Kevin Wolf <kwolf@redhat.com> block: Add bdrv_runtime_opts to query-command-line-options

Recently we moved a few options from QemuOptsLists in blockdev.c to
bdrv_runtime_opts in block.c in order to make them accissble using
blockdev-add. However, this has the side effect that these options are
missing from query-command-line-options now, and libvirt consequently
disables the corresponding feature.

This problem was reported as a regression for the 'discard' option,
introduced in commit 818584a4. However, it is more general than that.

Fix it by adding bdrv_runtime_opts to the list of QemuOptsLists that are
returned in query-command-line-options. For the future, libvirt is
advised to use QMP schema introspection for block device options.
