This also affects version 1.15.1.

attached error log

I can confirm that this issue is present on 1.15.2. I followed all the instructions on setting up NoVNC on Foreman 1.15.2. My Qemu/KVM server is running Centos 7 and I have SELINUX and IPTABLES disabled. My Foreman instance is running on Ubuntu 16.04. I can manage my KVM server from Foreman using the FQDN of the server and qemu+ssh, but whenever I launch the console I get:

Error: Failed to set console: Call to virDomainUpdateDeviceFlags failed: Operation not supported: cannot change keymap setting on vnc graphics

The instance I am trying to console into has en-us set as the keymap, there is no password, vnc is set up to listen on all interfaces and I have auto set up for the VNC port (5903).

If I manually set the VNC port to any port between 5910-5930 I get:

Error: Failed to set console: Call to virDomainUpdateDeviceFlags failed: Operation not supported: cannot change port settings on vnc graphics

In either case, I do not see websockify.py under processes, nor do I see anything significant in the production.log (with debug enabled). Every time I click on the console button, the only thing that pops up in the log is:

At this point, I think I've exhausted all possible options (to include updating the config settings in Firefox). I would really like to get this working if possible.

Cheers,
Carlos
