[PATCH 0/6 V2] Discover Kimchi peers using openSLP
v1 -> V2: - Update docs/API.md - Expose federation on /config/capabilities Aline Manera (6): Update kimchi.config values according to command line input Delete http_port from /config API as it is not in use anymore Add federation option to Kimchi config file Discover Kimchi peers using openSLP Add documentation on how to enable federation on Kimchi Expose federation on /config/capabilities docs/API.md | 11 ++++++++- docs/README-federation.md | 27 +++++++++++++++++++++ src/kimchi.conf.in | 4 +++ src/kimchi/config.py.in | 1 + src/kimchi/control/peers.py | 29 ++++++++++++++++++++++ src/kimchi/mockmodel.py | 14 ++++++++--- src/kimchi/model/config.py | 6 ++--- src/kimchi/model/peers.py | 59 +++++++++++++++++++++++++++++++++++++++++++++ src/kimchi/server.py | 1 - src/kimchid.in | 36 +++++++++++++++++---------- tests/test_rest.py | 19 +++++++++------ 11 files changed, 177 insertions(+), 30 deletions(-) create mode 100644 docs/README-federation.md create mode 100644 src/kimchi/control/peers.py create mode 100644 src/kimchi/model/peers.py -- 1.9.3
Kimchi allows users to change some configuration values by command line. Those values override the kimchi.conf values. That way we need to properly update kimchi.config.config to provide the accurate data for whole application.

http_port information was used to display the guest console But since we have changed how to redirect user to guest console by adding the ui/pages/websockify/console.html it is not in use anymore.
