OpenStack Compute (nova)

Bundling Images

Asked by naangilsunder

Hi,
  I Have configured Nova Environment in 2 Servers
          1, nova-api + nova-network + nova-objectstore + nova-scheduler
          2, nova-compute,nova-volume
       on Ubuntu 10.10, Hypervisor KVM

I bundled Ubuntu Images as per the below link

http://cssoss.wordpress.com/2010/05/10/eucalyptus-beginner%E2%80%99s-guide-%E2%80%93-uec-edition-chapter-4-%E2%80%93-image%C2%A0management/

My Bundling,image registration process went successfully. but i am not able to run the instance.

is this the right practice to bundle image? is there any other method for bundling the images.

How does running the instance fail?

Do you see anything useful in the console output (from
euca-get-console-output, for instance)?

There's your problem.

The image you've uploaded is in qcow2 format. It needs to be in raw format.

nova doesn't support whole disk booting (yet). The image needs to be just the main partition from your image (without a boot sector). If you are wanting to boot a whole disk image, you will need to wait for the lp:~dendrobates/nova/raw-disk-images to get merged.

Hi,

Once you've prepared your images, they can be bundled following the steps here: http://wiki.openstack.org/XenServerDevelopment#Instance_Management

You will want to note the euca-bundle* commands.
