I had running OPenStack 3 node architecture. I integrated OpenDayLight into
it. Compute node and control node are seen in DLUX. I am also able to
create router and networks in Horizon but not able to launch instances. The
error is as follows:

MessageNo valid host was found. Code500Details File
"/usr/lib/python2.7/dist-packages/nova/scheduler/filter_scheduler.py", line
108, in schedule_run_instance raise exception.NoValidHost(reason="")
5, 2015, 10:11 a.m.

On compute and control node, ovs-vsctl show result is:
    Manager "tcp:"
        is_connected: true
    Bridge br-int
        Controller "tcp:"
            is_connected: true
        fail_mode: secure
        Port br-int
            Interface br-int
    ovs_version: "2.0.2"

Can anyone tell what is the problem?
