Now that almost everything in my cloud is looking like
it's working almost perfectly (except a few minor issues
here and there), I decided to provision the other hosts
as Computes.

Everything on the new node(s) come up as it should (from
what it seems now anyway), but NOT the console service(s)!

When I had only one Control and one Compute, it worked just
fine. But as soon as I added a second (and third etc) Compute,
it just stopped working..


Please correct me if I'm wrong, but the following services
(packages) should be installed on the Control(s):

    nova-api
    nova-conductor
    nova-consoleauth
    nova-consoleproxy
    nova-scheduler
    nova-volume
    spice-html5

And on the Compute(s):

    nova-compute
    nova-compute-kvm
    nova-console

The configuration on the Control:

    [spice]
    html5proxy_host = 0.0.0.0
    html5proxy_port = 6082
    html5proxy_base_url = http://control:6082/spice_auto.html
    server_listen = 0.0.0.0
    server_proxyclient_address = control
    enabled = true
    agent_enabled = false

And the Compute console should connect to the Control:

    [spice]
    html5proxy_host = 0.0.0.0
    html5proxy_port = 6082
    html5proxy_base_url = http://control:6082/spice_auto.html
    server_listen = 0.0.0.0
    server_proxyclient_address = control
    enabled = true
    agent_enabled = true


The service list (bladeA0[12] is Control nodes, all other are
Compute nodes):

    bladeA01:/etc/nova# nova-manage service list 2> /dev/null
    Binary           Host                                 Zone             Status     State Updated_At

    nova-console     bladeA05                             internal         enabled    XXX   2016-07-24 19:04:26
    nova-console     bladeA04                             internal         enabled    XXX   2016-07-24 19:04:34

The 'bladeA03' was the first Compute being installed. That
still seems to be enabled, so maybe I've missed to document
a step to get this to work..
