Dear Marco,

Actually the question is for Devstack not Essex. I also face the same problem, the current Desvatack allows URL to be specified for image Creation I have specified URL of AMI format Bitnami Wordpress. Although the Image is said to be created the Instances are not getting launched from these AMI Images.

Hello,

as far as I know, using the dashboard, there's no way to either create an image or load, in the catalogue, an image you created.

For creating an image, you need to use kvm (see a description here http://forums.openstack.org/viewtopic.php?f=15&t=523&p=1716&hilit=red+hat#p1716 (http://forums.openstack.org/viewtopic...) ) or some tools specifically designed to do that (see http://docs.openstack.org/essex/openstack-compute/admin/content/creating-new-images.html (http://docs.openstack.org/essex/opens...) ). This means that starting from an installation ISO image, you create a boot-able "disk" or (better) a boot-able image.

Once you have created an image, you have to load it into the catalogue by calling glance's CLI. See here for details: http://docs.openstack.org/essex/openstack-compute/install/yum/content/uploading-to-glance.html (http://docs.openstack.org/essex/opens...) This second step actually reads the image (the file) and loads it into glance.


Alternatively you can download some per-fabricated image from a "free" catalogue you find in Internet (see, for example here http://www.turnkeylinux.org/ (http://www.turnkeylinux.org/?) ) and load such an image into glance (with the steps described in the previous step).
