image snapshots broken (disk config change causes glance plugin AttributeError)

[Dan Prince]

Using nova trunk a515337.

I'm now getting the following exception when trying to create an image snapshot w/ nova:

According to smokestack revision 532cd93 runs clean (and can create snapshots). It looks like 144b5e4 (Adds disk config) is the culprit here.

Hi ,
When am trying to create a snapshot from the Dashboard, am getting the error 403.
there is problem in nova/glance.py or glance/common/client.py. Its not able to get the Auth Token.
Are you able to get this error when trying to take snapshot?
