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             |
   +----+---------------------+
