nova-docker on mitaka unable to boot instances

Configured compute node with nova-docker with either the master branch or stable/mitaka branch, and when trying to boot docker instances, it does not boot up.

nova list shows the status is ACTIVE with assigned IP address with provider network. nova show <instance-id> does not show any error.

But on the compute node, docker ps does not show the docker image running.

vnc console shows mesage: no bootable device

and I also noticed that in the liberty release, the hypervisor type for compute node is 'docker' but with mitaka release, it is set us 'QEMU'

Any help is appreciated.

docker ps -a shows the container? vnc won't work because probably the container don't have any vnc connection method

1.If it's possible post Dockerfile been used to build docker image uploaded to Glance.
2.Test ubuntu/rastasheep or tutum/tomcat to be loaded as Nova-Docker instances
The last images have been tested hundreds of times ( positive ) with Nova-Docker (Mitaka,Liberty,Kilo )

docker ps -a does not show the container on compute host

tried to boot tutum/tomcat, same issue.

It's a fair Nova-Docker (Mitaka,Liberty) works fine. You made some mistakes during driver installation
See for instance https://www.linux.com/blog/java-serve...

I followed instructions from http://egonzalez.org/nova-docker-driver/ the same instruction works for liberty, but not for mitaka.

rootwrap needs to be setup on all hosts (controller + all compute hosts)

vi /etc/nova/rootwrap.d/docker.filters

[Filters]
# nova/virt/docker/driver.py: 'ln', '-sf', '/var/run/netns/.*'
ln: CommandFilter, /bin/ln, root

It was not setup on controller which caused the issue
