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

You have a problem with nova-api service on Controller:

netstat -lntp | grep 8774
iptables-save | grep 8774
ps -ef | grep nova-api

It should look like this :-

[root@juno1 ~(keystone_admin)]# netstat -lntp | grep 8774
tcp        0      0 0.0.0.0:8774            0.0.0.0:*               LISTEN      1663/python         
[root@juno1 ~(keystone_admin)]# iptables-save | grep 8774
-A INPUT -p tcp -m multiport --dports 8773,8774,8775 -m comment --comment "001 nova api incoming nova_api" -j ACCEPT
[root@juno1 ~(keystone_admin)]# ps -ef | grep 1663
nova      1663     1  0 08:56 ?        00:02:00 /usr/bin/python /usr/bin/nova-api
nova      3569  1663  0 08:56 ?        00:00:00 /usr/bin/python /usr/bin/nova-api
nova      3572  1663  0 08:56 ?        00:00:00 /usr/bin/python /usr/bin/nova-api
nova      3653  1663  0 08:56 ?        00:00:06 /usr/bin/python /usr/bin/nova-api
nova      3655  1663  0 08:56 ?        00:00:06 /usr/bin/python /usr/bin/nova-api
nova      3702  1663  0 08:56 ?        00:00:00 /usr/bin/python /usr/bin/nova-api
nova      3703  1663  0 08:56 ?        00:00:00 /usr/bin/python /usr/bin/nova-api
