Local ISO server
================

ISO Web Server
--------------

It is pointless and resource consuming download each time the ISO files
from the Internet. Set up a webserver in the main host and let the
development virtual ravadas download them from there.

Copy the ISO files
~~~~~~~~~~~~~~~~~~

Copy the ``.iso`` files to the directory ``/var/www/html/iso``.

::

    $ sudo mkdir /var/www/html/iso
    $ sudo cp /var/lib/libvirt/images/*iso /var/www/html/iso

Apache
------

Install Apache
~~~~~~~~~~~~~~

Install apache web server:

::

    $ sudo apt-get install apache2

Config apache
~~~~~~~~~~~~~

Configure it so ISOs are donwloaded from the storage pool, and only the
local virtual network is able to access to it.

Edit */etc/apache2/sites-enabled/000-default.conf* and add:

::

    <Location /iso>

        Options FollowSymLinks
        AllowOverride None

        Allow from localhost
        Allow from 192.168.122.0/24
        Deny from all

        Require all granted
        Options +Indexes

    </Location>

Restart apache
~~~~~~~~~~~~~~

::

    $ sudo systemctl restart apache2

Change the ISO locations
------------------------

In the table iso\_images there is an entry that states where are located
original ISO files, change it.

From localhost
~~~~~~~~~~~~~~

If you want to access to the ISO files from localhost change the *URL*
field to this:

::

    $ mysql -u root -p ravada
    mysql> update iso_images set url = 'http://127.0.0.1/iso/';

From Virtual Machines
~~~~~~~~~~~~~~~~~~~~~
If you install ravada in a virtual machine inside the host you have to
change the URLs to the virtual address, it will probably be
``192.168.1.1``, check it is doing

::

    $ ifconfig virbr0


    $ mysql -u root -p ravada
    mysql> update iso_images set url = 'http://192.168.122.1/iso/';

Try it
------

Remove the ISO from the storage and from the table

Remove from the VM storage pool
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

::

    $ sudo rm /var/lib/libvirt/images/*iso

Remove the device name from the table
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First find out the id of the iso image, then remove it.

::

    $ mysql -u root -p ravada
    mysql> select id,name FROM iso_images;
    mysql> update iso_images set device = null where id=9;

Restart rvd\_back and reload the admin page and verify Ravada won't
download them from Internet the next time you try to install a new
machine.

::

    $ sudo ./bin/rvd_back.pl --debug
