Hi all. I have a small kilo deployment (virtualbox, Fuel 7.0, 1 Controller 1 Compute) and I am trying to use nova docker. After following the instructions from https://wiki.openstack.org/wiki/Docker (and others ) I managed to get the hypervisor to be reported as docker in Horizon. However I cannot spawn containers. Because no [Error: No valid host was found. There are not enough hosts available.]. The Nova-compute log helps and it reports :

So I looked a bit in the python modules and this is what i Got. From what I understand Nova requests the image from glance. Glance also has to report some metadata (fe Json) which describe the image. One of these fields is 'container_format' which for some reason does not exist. If however i run glance image-show the attribute is listed correctly.

Can anybody help?

EDIT: By installing from stable/kilo and not from trunk the issue was resolved
