[ovirt-users] Questions regarding neutron implementation for oVirt 3.5

-----Original Message----- From: Andrew Brimer Sent: Wednesday, December 10, 2014 10:56 AM To: 'Moti Asayag' Subject: RE: Questions regarding neutron implementation for oVirt 3.5 Hi Moti, Yes. I did not consider sending this out in a way that everyone would benefit, sorry. This is the first time that I have posted a question for oVirt and just saw your email address in the instructions document and quickly fired off an email. I will post to users(a)ovirt.org for all future questions, I would love to participate in any way possible to help you guys (and those of us who rely on your efforts) move things forward. If you would like for me to forward the next (or this one) message to users(a)ovirt.org I would be very happy to. To answer your question regarding testing connectivity, yes I pressed the test button and was provided the success message. In addition to that, when I create a net and subnet in oVirt I am able to query neutron and find them. I can also create a net in neutron (neutron net-create) and import it into oVirt. It seems that the two systems are communicating but that somewhere along the way an error is halting your workflow (see the snippit from the /var/log/ovirt-engine/engine.log) Output (subset) of the /var/log/ovirt-engine/engine.log: 2014-12-10 14:41:23,623 ERROR [org.ovirt.engine.core.bll.provider.network.GetExternalSubnetsOnProviderByNetworkQuery] (ajp--127.0.0.1-8702-3) Query GetExternalSubnetsOnProviderByNetworkQuery failed.

to send ovirt related questions to users(a)ovirt.org for the benefit of other community members. If no concerns, please include it in your next reply's cc. Regarding your issue - see inline. ----- Original Message ----- Were you able to verify connectivity to the neutron appliance after it was added to the ovirt-engine as shown on https://www.youtube.com/watch?feature=player_detailpage&v=naLFSFwHI94... Could you post the /var/log/ovirt-engine/engine.log ? Thanks, Moti
