Selecting Hosts to Launch Instances

To create and launch an instance on a specific host you must be logged in as an administrator.

  1. Select the host where instances are launched using the --availability-zone ZONE:HOST parameter on the openstack server create command.

    For example:

    $ openstack server create --image <UUID> --flavor m1.tiny --key_name test --availability-zone nova:server2
    
  2. To view the list of valid compute hosts, use the openstack hypervisor list command.

    $ openstack hypervisor list
    +----+---------------------+
    | ID | Hypervisor Hostname |
    +----+---------------------+
    | 1  | server2             |
    | 2  | server3             |
    | 3  | server4             |
    +----+---------------------+
