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
