Procedure 8.5. Creating a Compute Network

  1. Use the keystonerc_admin file to authenticate with the Identity service. 
    $ source ~/keystonerc_admin
  2. Create a network that virtual machines can use. Do this once for the entire installation and not on each Compute node. 
    $ nova network-create NETWORKNAME --fixed-range-v4=FIXEDRANGE_IP --bridge-interface=BRIDGE_INTERFACE --multi-host=MULTI_HOST
    ⁠

    Example 8.3. Creating a OpenStack Network using Compute Networking

    $ nova network-create vmnet --fixed-range-v4=10.0.0.0/24 --bridge-interface=br100 --multi-host=T
    You have successfully created a network using Compute networking that the virtual machines can use.
