Looks like a configuration issue in glance/nova. I would suggest you to look at or share debug logs and versions of python-glanceclient

[Matt Riedemann (mriedem)]

This might be related to what Eric Fried is doing with keystoneauth adapters for configuration in Queens (current master).

[Matt Riedemann (mriedem)]

What does the [glance] section of your nova.conf look like? Because it looks like you might have a full URL reference to an image in there? That would be wrong.

'api_server = http://controller:9292/v2/images/6c861554-35b2-49eb-8dbf-a2a51bc1d07a'

[Matt Riedemann (mriedem)]

Or maybe the 'image' entry in the service catalog does not match 'controller:9292'? What does "openstack catalog list" look like?

[Eric Fried (efried)]

What version is this? Pike? What's the version of keystoneauth? Looks like could be 3.1.0? Your confs will probably be needed.

This could be a missing/invalid service catalog entry for glance. Does the URL displayed by

openstack endpoint list --service glance

match what you've listed in your nova compute conf under [glance]api_servers ?
