Hi, You have configured the region during keystone setup. I believe the most common default would be something like 'RegionOne', but try to run keystone catalog and check your setting. Marek From: varun bhatnagar [mailto:varun292...@gmail.com] Sent: 22. januára 2014 10:54 To: Ruzi

Hi Jon, By any chance, do you have any kind of asymmetric routing in place? This is definitely a long shot, since I have no idea about your setup, but we have experienced similar issues ourselves. In our case it was problem with asymmetric routing and rather dumb linux defaults when it comes to

I second that question… We have a registration system that is creating users/tenants/etc and also taking care of these security groups (deleting defaults, creating custom ones). If it was possible to configure default sec groups, it would be one less thing to deal with. Marek From: Nick Maslov

I’m not 100% sure, but I remember (depending on the driver you are using) it used to zero entire volume before deletion, which might or might not make sense for you. Sorry for not being able to provide any details, this is just something I remember from way back. Cheers, Marek From: Udara Liya

Hi Tiago, I’m not sure if I’m following… Are you trying to create L2 network with Neutron and then handle the L3 from within the instance? If that is so… there is no good way how to do it as far as I can tell. At least no until Juno release as I was told… Even with Provider network, Neutron wi
