[1.10-Build 63] On Icehouse, Horizon has internal server error, when Networking is clicked.

[Daisuke Nakajima]

On Icehouse, Horizon has internal server error, when Networking is clicked. Because 'Client' object has no attribute 'list_policys'.
This error is not seen on Havana.

The test environment:
Base OS: Ubuntu 1204/1404

[Daisuke Nakajima (dnakajima)]

This issue is seen in Project -> Other -> Networking TAB but that is not seen in Admin -> Other -> Networking TAB.

[Daisuke Nakajima (dnakajima)]

This issue is only seen at Ubuntu14.04.1 with Icehouse.
/usr/lib/python2.7/dist-packages/neutronclient/v2_0/client.py is different with Ubuntu1204.
client.py which is downloaded from 1404 repository does not have 'list_policys' Class.

I replaced client.py which is downloaded from 1204 repository, this error did not seem.

Please confirm following two repository.
http://ubuntu-repo.opencontrail.org.s3-website-us-east-1.amazonaws.com opencontrail-stock-ubuntu1404-icehouse main
http://ubuntu-repo.opencontrail.org.s3-website-us-east-1.amazonaws.com opencontrail-r120-icehouse main

[Peter C. Norton (spacey-launchpad-net)]

Do you have version or git has info for the working fersion of neutron/v2_0/client.py for icehouse on 12.04? I have a new 12.04 installation and I'm seeing this problem with the following sources:

root@kvm-openstack-5:~# cat /etc/apt/sources.list.d/opencontrail.list
deb [arch=amd64] http://ubuntu-repo.opencontrail.org.s3-website-us-east-1.amazonaws.com opencontrail-stock-ubuntu1204-icehouse main
deb [arch=amd64] http://ubuntu-repo.opencontrail.org.s3-website-us-east-1.amazonaws.com opencontrail-r120-icehouse main

[Peter C. Norton (spacey-launchpad-net)]

Here's a quick workaround:

https://gist.github.com/pcn/9684bde1f8c9bd965596

This removes calls to what are probably depricated neutron API calls.

[Atul Moghe (moghea)]

Hi Peter,
This particular build R1.10/63 was for 12.04/icehouse not for 14.04.
14.04/icehouse is targeted to release with contrail 2.0

Thanks,
Atul

[Martin Gerhard Loschwitz (martin-loschwitz)]

This is still happening on 14.04 with Icehouse and Contrail R2.0.

[Martin Gerhard Loschwitz (martin-loschwitz)]

Installing the neutronclient package from https://github.com/Juniper/python-neutronclient/tree/contrail/icehouse makes it work.

[Martin Gerhard Loschwitz (martin-loschwitz)]

Well, sort of. I now see:

2014-12-16 12:32:48,333 9568 WARNING horizon.exceptions Recoverable error: 404 Not Found

The resource could not be found.

[Martin Gerhard Loschwitz (martin-loschwitz)]

I managed to make the thing work. The packages available from https://launchpad.net/~syseleven-platform/+archive/ubuntu/contrail-1.20 will lead to a working Horizon on Icehouse with the Contrail plugin enabled.

[Atul Moghe (moghea)]
