I did a fresh re-install of devstack.
Now I got the URL for the console.
localadmin at qa4:~/devstack$ nova get-vnc-console vm1 novnc
+-------+-------------------------------------------------------------------------------------+
| Type | Url |
+-------+-------------------------------------------------------------------------------------+
| novnc | http://172.29.172.161:6080/vnc_auto.html?token=9ced0dd0-f146-42eb-9b26-c64a29443936 |
+-------+-------------------------------------------------------------------------------------+
However, when attempt to connect to the URL, error "Failed to connect to server (code: 1006)" is returned at the web page.
The following traceback is logged in the Controller's screen-x-n-novnc.log:

Devstack is used to deploy OpenStack. I enabled the “n-novnc” service at the Compute node.
Below is a snippet of the localrc.
Compute:
# Services
disable_all_services
ENABLED_SERVICES=neutron,n-cpu,rabbit,q-api,q-agt,n-novnc
Controller:
# Services
disable_service n-net
disable_service n-cpu
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service neutron
The process n-novnc is running at both the Controller and Compute nodes.
Is this a misconfiguration issue?
Thanks,
Danny

No this is not expected and may represent a misconfiguration or a bug. Something
is returning a 404 when it shouldn?t. You might get more luck running the nova command
with ?debug to see what specifically is 404ing. You could also see if anything is reporting
NotFound in the nova-consoleauth or nova-api or nova-compute logs

Hi,
I used devstack to deploy multi-node OpenStack, with Controller + nova-compute + Network on one physical node (qa4),
and Compute on a separate physical node (qa5).
When I launch a VM which spun up on the Compute node (qa5), I cannot launch the VM console, in both CLI and Horizon.

Is this expected behavior?
