Ocata -> Pike upgrade: openstack-nova-compute service is running on host after upgrading to containers architecture

[Marius Cornea]

As first discussed at https://bugzilla.redhat.com/show_bug.cgi?id=1477768 Ocata -> Pike upgrade: openstack-nova-compute service is running on host after upgrading to containers architecture

After stopping and disabling the openstack-nova-compute service on the host and starting the nova-compute container the service comes back ok:

[root@compute-0 heat-admin]# systemctl stop openstack-nova-compute
[root@compute-0 heat-admin]# systemctl disable openstack-nova-compute
Removed symlink /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service.
[root@compute-0 heat-admin]# docker stop nova_compute
docker start nova_compute
nova_compute
[root@compute-0 heat-admin]# docker start nova_compute
nova_compute
