[ovirt-users] using ovirt-scheduler-proxy

[Amedeo Salvati]

   hello guys,
   I'm triyng to use ovirt-scheduler-proxy, and for this, now, I'm starting with examples available on:
   https://github.com/oVirt/ovirt-scheduler-proxy/tree/master/doc/plugin_samples
   so, on ovirt 3.5 fresh installation I've installed ovirt-scheduler-proxy package (by yum), then I've downloaded from above link host_memory_balance.py file under /usr/share/ovirt-scheduler-proxy/plugins directory, I've changed the connection string due to reflect my ovirt engine hostname/port/user/password, and finally I've started the service:
   service ovirt-scheduler-proxy start
   on log ovirt-scheduler-proxy.log I got:
   [root at engine ovirt-scheduler-proxy]# cat /var/log/ovirt-scheduler-proxy/ovirt-scheduler-proxy.log

   Tue, 04 Nov 2014 16:01:18 INFO     [process:MainProcess, thread:MainThread] Publishing API
   [root at engine ovirt-scheduler-proxy]#
   but after that on web ui I can't see any change under cluster policy and under Configure -> Cluster Policies (host_memory_balance balancers is not displayed)
   what did I miss?
   Best regards
