With the split of the User Guides, there's no need anymore to have orphan and admin_only flags, remove them from the user-guide-admin directory. Change-Id: Id30666b87c7b0ae9fb6c2997cac62e8d52651dec

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 ``--availability_zone ZONE:HOST`` parameter on the
|
|
:command:`nova boot` command.
|
|
|
|
For example::
|
|
|
|
$ nova boot --image <uuid> --flavor m1.tiny --key_name test --availability-zone nova:server2
|
|
|
|
#. To specify which roles can launch an instance on a
|
|
specified host, enable the :code:`create:forced_host` option in
|
|
the :file:`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:`nova hypervisor-list` command, as follows::
|
|
|
|
$ nova hypervisor-list
