VNC setup issues connecting to console

Hello all, I've just installed two servers. One All-in-one (AIO) Packstack distribution, running on CentOS 7. I have later added a compute node to this configuration. I am having issues opening the console for the instances that I create on both server, and I'm unsure of the configuration settings for /etc/nova/nova.conf, with respect to VNC. I need assistance understanding what should be the correct configuration of nova.conf for vnc connectivity. I haven't been able to consistenly open the Console for the instances I create. My setup is the following: Controller/Network/Compute (All-in-one) Host 1 IP Address: 10.200.127.17 Compute Host 2 IP Address: 10.200.127.16 What should be the setup for /etc/nova/nova.conf on each host? I'm mainly interested in understanding the defition of the following values: novncproxy_host=0.0.0.0 novncproxy_port=6080 novncproxy_base_url=http://0.0.0.0:6080/vnc_auto.html # # vnc_enabled=True novncproxy_base_url=http://0.0.0.0:6080/vnc_auto.html vncserver_listen=0.0.0.0 vncserver_proxyclient_address=0.0.0.0
