Boot an instance from an ISO image
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
OpenStack supports booting instances using ISO images. But before you
|
|
make such instances functional, use the :command:`openstack server create`
|
|
command with the following parameters to boot an instance.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack server create \
|
|
--image ubuntu-14.04.2-server-amd64.iso \
|
|
--block-device source=blank,dest=volume,size=10,shutdown=preserve \
|
|
--nic net-id = NETWORK_UUID \
|
|
--flavor 2 INSTANCE_NAME

In this command, ``ubuntu-14.04.2-server-amd64.iso`` is the ISO image,
|
|
and ``INSTANCE_NAME`` is the name of the new instance. ``NETWORK_UUID``
|
|
is a valid network id in your system.
|
|
|
|
.. note::
|
|
|
|
You need the Block Storage service, and the parameter
|
|
``shutdown=preserve`` is also mandatory, thus the volume will be
|
|
preserved after the shutdown of the instance.
|
|
|
|
After the instance is successfully launched, connect to the instance
|
|
using a remote console and follow the instructions to install the
|
|
system as using ISO images on regular computers. When the installation
|
|
is finished and system is rebooted, the instance asks you again to
|
|
install the operating system, which means your instance is not usable.
|
|
If you have problems with image creation, please check the
|
|
`Virtual Machine Image Guide
|
|
<http://docs.openstack.org/image-guide/create-images-manually.html>`_
|
|
for reference.

.. _Make_instance_booted_from_ISO_image_functional:
|
|
|
|
Make the instances booted from ISO image functional
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Now complete the following steps to make your instances created
|
|
using ISO image actually functional.
|
|
|
|
#. Delete the instance using the following command.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack server delete INSTANCE_NAME
|
|
|
|
#. After you delete the instance, the system you have just installed
|
|
using your ISO image remains, because the parameter
|
|
``shutdown=preserve`` was set, so run the following command.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack volume list
|
|
+--------------------------+-------------------------+-----------+------+-------------+

|
|
| 1025f4264e4f | 26a8d955a1d9-blank-vol | | | |
|
|
+--------------------------+-------------------------+-----------+------+-------------+
|
|
|
|
You get a list with all the volumes in your system. In this list,
|
|
you can find the volume that is attached to your ISO created
|
|
instance, with the false bootable property.
|
|
|
|
#. Upload the volume to glance.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image create --volume SOURCE_VOLUME IMAGE_NAME
|
|
$ openstack image list
|
|
+-------------------+------------+--------+

|
|
| 74303284-f802-... | IMAGE_NAME | active |
|
|

|
|
|
|
The ``VOLUME_UUID`` is the uuid of the volume that is attached to
|
|
your ISO created instance, and the ``IMAGE_NAME`` is the name that
|
|
you give to your new image.
|
|
|
|
#. After the image is successfully uploaded, you can use the new
|
|
image to boot instances.
|
|
|
|
The instances launched using this image contain the system that
|
|
you have just installed using the ISO image.
