Hi,
I am new to OpenStack.
I am doing a single node node OpenStack setup (Control and Compute) for POC purpose. My document reference is : http://docs.openstack.org/icehouse/install-guide/install/apt/content/ ....
Till nova-compute service configuration every thing went fine. the "nova -list" commands were working fine. Soon after I configured "nova netwrok" by following the document "http://docs.openstack.org/icehouse/install-guide/install/apt/content/ch_networking.html". adding the necessary attributes in "/etc/nova/nova.conf*".
tried to execute the command:
"nova network-create demo-net --bridge br100 --multi-host T --fixed-range-v4 192.168.10.24/29"
The error I got is:
"ERROR: HTTPConnectionPool(host='192.168.78.145', port=8774): Max retries exceeded with url: /v2/6bf0bcb4a1e145afa699f0660b7505ae/os-networks (Caused by <class 'socket.error'>: [Errno 111] Connection refused)"
