docker is not in the nova tree any more, so this is no longer in scope
for nova.

Title:
  Container servers are wrongly scheduled to non-docker hypervisor

Status in OpenStack Compute (nova):
  Won't Fix

Bug description:
  In an environment with more than one hypervisor type including QEMU and
  docker, when creating a container server, the request can be wrongly
  scheduled to a QEMU hypervisor.

  I test it in Juno and there is the same bug in Kilo.

  For example,  there is two compute node, one hypervisor is docker
  (node A-172), anther one hypervisor is QEMU(node B-168).

  I can create a docker server which uses docker image "tutum/wordpress" in a QEMU node(node B-168).
  In this case it ignores the parameter “image" whether is match the hypervisor type, finally this server
  boot failed with "no bootable device".

  I'm not sure is there any other parameter for QEMU,  docker and Xen
  hypervisor should check.

  My step is following:
