Subject: [PATCH] Add a qemuMonitorGetObjectProps() method for QMP
device-list-properties command
https://bugzilla.redhat.com/show_bug.cgi?id=863115
Add a new qemuMonitorGetObjectProps() method to support invocation
of the 'device-list-properties' JSON monitor command. No HMP equivalent
is required, since this will only be present for QEMU >= 1.2
Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
(cherry picked from commit b785cec0dc53653054647e246c314ea115a60d0d)
