[Qemu-devel] [PULL 1/2] input: fix send-key monitor command release event ordering

[Gerd Hoffmann]

commit 2e377f1730d06deafb3e3ef6cf88792de4a6f4df changed the ordering
of the release events as side effect.  Some guests are not happy with
that and don't recognise ctrl-alt-del any more.  This patch restores
the old last-pressed first-released behavior.

+Send input event to guest.

+
+The consoles are visible in the qom tree, under
+/backend/console[$index]. They have a device link and head property, so
+it is possible to map which console belongs to which device and display.
