hypervisors went wrong in dashboard
just completed installation of neutron(juno). i login dashboard with admin account, every page looks good, but only hypervisors page went wrong, saying unexpected error. tried to do "nova service-list" on compute node, it responsed like below
ERROR (ConnectionError): HTTPConnectionPool(host='controller', port=8774): Max retries exceeded with url: /v2/1ce2678eeaf44a62a938d08b44135702/os-services (Caused by <class 'socket.error'>: [Errno 111] Connection refused)
there is nothing in /var/log/nova-compute.log
tried nova-manage service list just now, found out there is something written on juno document, which can be easily make it wrong formation. here is the error
oslo.config.cfg.ConfigFileParseError: Failed to parse /etc/nova/nova.conf: at /etc/nova/nova.conf:25, No ':' or '=' found in assignment: 'LinuxOVSInterfaceDriver'.
i simply copy and paste in nova.cfg about this section, then it went wrong. well the juno document shows this cli in two lines like below. but actually it should be one line, such us "nova.network.linux_net.LinuxOVSInterfaceDriver" linuxnet_interface_driver = nova.network.linux_net. LinuxOVSInterfaceDriver
