2016-03-17 04:16:04 -0500 answered a question How to change hostname of instance

in the /etc/cloud/cloud.cfg

Remove the ‘ – update_hostname’ line.

And your hostname will not be updated on reboot. It will take the name from /etc/hostnames

2016-03-08 22:19:34 -0500 commented question Kilo: Network Node External Network unreachable?

If you can ping the 192.168.137.104 in the qrouter-c49868c0-2f77-49ff-bcc7-946c48a1c45c, and it should be no problem ? You can't ping your external gateway 192.168.137.1. I'm pretty sure you have a network problem outside of openstack. So I think you need to ckeck why eth2 can't talk to your networ

2016-03-08 08:26:40 -0500 commented question Kilo: Network Node External Network unreachable?

Yes, its normal that your qg interface is under br-int at least liberty. so i guess its the same in kilo. can you ping your router ip from internet ? can you reach the external gateway from ip netne exec qr.. ping ?

2016-03-07 05:04:09 -0500 answered a question can't ping external gateway

It turned out to be a network problem. The interface eth3 was not conected to the correct network.

It had no chance to succeed. It was tcpdump that helped me to understand that the traffic was not arriving to the interface.

I have not configured br-ex with an ip adress, so that is not requirerd.

2016-03-06 22:22:59 -0500 asked a question can't ping external gateway

I have problem to get acces to external network. I user the ovs-dvr setup. My external interface is connected to eth3

my setup

ip netns 
snat-dd11b70d-9222-4553-8458-ee70ab1a139b
qrouter-dd11b70d-9222-4553-8458-ee70ab1a139b
qdhcp-afd14f37-5493-474b-818a-018a9a2ee0d7

Routing And ip's in Router i think ?

netns exec snat-dd11b70d-9222-4553-8458-ee70ab1a139b route -n
