[libvirt] [PATCH 15/15] Start of support for JSON based QEMU monitor protocol
Daniel P. Berrange
berrange at redhat.com
Tue Nov 3 19:50:09 UTC 2009
Initial support for the new QEMU monitor protocol using JSON
as the data encoding format instead of plain text
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Hack to turn on QMP
mode
* src/qemu/qemu_monitor.c: Delegate to json monitor if enabled
* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add
impl of QMP protocol
* src/Makefile.am: Add src/qemu/qemu_monitor_json.{c,h}
