OpenStack PackStack All-in-One

Latest response

For a proof-of-concept I've requested and been provided a sixty-day demo of OpenStack 4. My goal is to demostrate OpenStack quickly, so using the Getting Started Guide I've intalled the all-in-one version of PackStack. PackStack is a very good way to instantly get OpenStack up and running. Having accomplished that let's create a golden-image Red Hat Linux server.

To this end I log onto the dashboard as "admin" and to the left select the existing project tab named "demo". Then I click Images and Snapshots and make the ISO image for RH 6 available. I'm certain the image is useful because I can Lauch an Instance using Instance Boot Sourcd -> Boot from Image, with the Image Name drop-down as "RH 6.5". The instance starts running and I can connect the the console and see the messages typical for a Red Hat install from DVD.

So far so good.

But now I'm a little confused on how to create a useful virtual machine. Using the steps I detail above, I continue with the installation dialog (Choose a Language, Keyboard Type, Installation Method -> Hard Drive, Select Partition -> /dev/vda1, Welcome to Red Hat -> Ok). The installation process presents a warning Error processing drive, for a "Virtio Block Device. I'm offered the chance to ignore or reinitialize. Regardless of the choice the next window says: "Unknown Device The installation source given by device ['/dev/vda1'] could not be found. Please check your parameters and try again. -> Exit installer."

I don't understand how I booted from ISO, but the installation can't seem to see the DVD to conduct an actual install.

Advice?

William,
The power of the OpenStack, comes from being able to use pre-built cloud images. These are generally small basic images that can be upgraded or have whatever application you need on it. Red Hat offers both a RHEL 6.4 and RHEL 6.5 guest images that can be used in conjunction with OpenStack.

This page should be accessible if you have a base RHEL Server subscription. Besides for Red Hat's guest images you can also find a variety of images available from the RDO site. http://openstack.redhat.com/Image_resources.

If you want to build an image from scratch I would recommend looking into Oz which is a library and utilised for automated guest OS installations.
