Hello,

I'm trying to install nova-docker with openstack stable/kilo.

I have three machine (Controller(VM), Compute1(VM), Compute2(Physical Machine)). Then All VMs(controller, compute1) has ubuntu-14.04.2, kernel-3.16.0, and PM(compute2) has a ubuntu-14.04.3, kernel-3.19.0

I installed OpenStack to Compute1 and Compute2 with exactly with same procedures via DevStack.

problem is that compute1 working well for attaching interface (I mean "creating instance -> attaching additional interface"), but compute2 doesn't working(creation working but not work for attaching additional interface).

I used below command to attach interface

nova interface-attach --net-id=d69c4fbc-a664-4fb5-960c-4f97e83b4aac test-docker

below log is n-cpu log.
