Hi kakuma,
I have construct a Juno OpenStack using different machines
and test it, but the result seems to be similar...

Is this mean, I don't have to execute /usr/bin/neutron-ofagent-agent
after the host is rebooted?
I might misunderstand it. Thank you for the information.
Then, after the host is rebooted, I should be able to
execute Ryu program directly.
I have just execute a sample from Ryubook (and sample code
distributed with Ryu), simple_switch_13.py, on a compute node.
But it returns the following error:
--------------------------------------------------------
# ovs-vsctl set Bridge br-int protocols=OpenFlow13

--------------------------------------------------------
I'm not so sure about how the OFAgent is executed
on a compute node, so I may misunderstand something
when Ryu program is executed...
The result is similar when the IceHouse OpenStack
is used.
Could you recognize what happens in this case?
Best regards,
Masato Oguchi
