[Qemu-devel] [PATCH 1/1] QMP test code - qmp.py

[Costas Drogos]

Hello there,

a very small patch to address two small issues:

1) The json state in python2.5 and python2.6. json module is included
by default on python2.6, whereas you have to import simplejson in
python2.5. I have this problem on Debian testing, so feel free to test
if this is applicable in your distribution.

2) For qmp commands to work (e.g. query-kvm) we have to give first the
command 'qmp_capabilities' because monitor is in 'Capabilities
Negotiation mode' on startup. The patch takes care of issuing that
command immediately after connecting.

The patch is more of a hack to ease qmp testing and development.
