Select hosts where instances are launched
|
|
=========================================
|
|
|
|
With the appropriate permissions, you can select which
|
|
host instances are launched on and which roles can boot instances
|
|
on this host.
|
|
|
|
#. To select the host where instances are launched, use
|
|
the :option:`--availability-zone ZONE:HOST` parameter on the
|
|
:command:`openstack server create` command.
|
|
|
|
For example:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack server create --image IMAGE --flavor m1.tiny \
|
|
--key-name KEY --availability-zone ZONE:HOST \
|
|
--nic net-id=UUID SERVER
|
|
|
|
#. To specify which roles can launch an instance on a
|
|
specified host, enable the ``create:forced_host`` option in
|
|
the ``policy.json`` file. By default, this option is
|
|
enabled for only the admin role.
|
|
|
|
#. To view the list of valid compute hosts, use the
|
|
:command:`openstack hypervisor list` command.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack hypervisor list
