Thesedays I want to update nova version 15.02 to 15.0.8.So I git clone the code from github,and run:

pip install .

After that,the controller and compute nodes all successfully update the nova version:

root@controller:~# nova-manage version

But there's error when run openstack cli.

root@controller:~# openstack server list
Unable to establish connection to http://controller:8774/v2.1/servers/detail (http://controller:8774/v2.1/servers/d...): HTTPConnectionPool(host='controller', port=8774): Max retries exceeded with url: /v2.1/servers/detail (Caused by NewConnectionError('<requests.packages.urllib3.connection.httpconnection 0x7f3e0e619950="" at="" object="">: Failed to establish a new connection: [Errno 111] Connection refused',))</requests.packages.urllib3.connection.httpconnection>

It seems that the connection between controller and compute was lost.How to solve this problem?
