The nova-docker finally worked for me. Now I can launch containers with nova, in the dashboard it is said that the instances are running. But when I try to go into the containers I fail. It seems that the problem is due to networking issues. Nova fail to create netns for the containers in question and thus all what comes after fail as well.
When I check the compute.log I find these messages. Would you please take a look and see if they are familiar to you and if so suggest me something ?
Any suggestion or hint would be very appreciated.
Thank you all ^^,
Sara
