2016/11/15 |
|
Install and Configure OpenStack Compute Service (Nova).
|
|
| [1] |
Install KVM HyperVisor like here.
It's unnecessarry to set Bridge networking manually. |
| [2] | Add users and others for Nova in Keystone. |

| [5] | Configure Networking. The follows is for the case you use legacy nova-network function. But if you use Neutron Networking function, Refer to here to configure it. Anyway, legacy nova-network function is officially not recommended. |
