Troubleshooting console access

The URL for console access is generated from a property that is set on each compute node. Look at the nova.conf file on one of your compute nodes for the novncproxy_base_url property:

novncproxy_base_url=http://control.example.com:6080/vnc_auto.html

This base URL is the address of the nova-novncproxy service that will be able to create a console connection to the instance. In the web interface, this URL is retrieved for you when you select the console tab for an instance. At the command line, you can use Nova's get-vnc-console and pass the novnc type to get the console URL:

$ nova console url show --novnc {instance-id}

This will return a URL that will include base_url from the compute node the instance is running on ...
