Horizon/Nova interactions broken

[Rob Cresswell]

This has occurred within the past few days. There are probably two distinct errors here, one related to listing extensions and the other related to using absolute limits.

Downgraded to python-novaclient 6.0.0 and everything works as expected.

Nova API logs: http://paste.openstack.org/show/595825/

What do the nova-api logs look like for the req-b96b3a99-884f-40f3-ac49-86e87d0bdcae request?

The fact that this is a 403 and not a 400/500 makes me wonder if there is a policy enforcement issue here.

There were a number of deprecations in python-novaclient this release.

If I had to guess (without much digging), I suspect it has to do with the deprecations that were done in the following series; especially if it's project id related.

Perhaps this, in particular:

But I could be wrong ;)

I can dig more on Monday. Have a great weekend, folks!

[Diana Clarke (diana-clarke)]

After a bit more digging, I take those initial hunches back, but I'll circle back Monday if no one beats me to it.

I looks like Istvan & Andrey found the root cause. Thanks!
