[Openstack] Adding Ubuntu Images to Xenserver Powered Devstack

The qcow2 images provided by Ubuntu aren't set up correctly for the Xen console - this means that the output during the boot process doesn't go to the screen.

If you leave the image it should eventually (after perhaps 5 minutes on first boot) reach the login prompt.

If you have injected credentials then you should be able to login using them, however I believe that if you have left it to Ubuntu to generate a random password this is displayed on the screen at a point which is not visible through the VNC console.

The three-part images do not suffer from this, and are set up correctly for the Xen console.

I installed devstack on top of xenserver. Now I want to add a ubuntu image to it. I downloaded qcow2 image from here ( http://cloud-images.ubuntu.com/precise/current/) and used the guideline here (http://blogs.citrix.com/2012/10/17/upload-custom-images-to-a-xenserver-powered-openstack-cloud/) to convert the image to vhd format and add to openstack using glance.

But when I start the instance, it got shut-off automatically. When I try to restart the instance in Xensenver, it got stuck at the messages:

[ 1.612617] EXT4-fs (xvda1): mounted filesystem with ordered data mode. Opts: (null)

[ 2.245259] EXT4-fs (xvda1): re-mounted. Opts: (null)

One thing to mention is that I successfully added a cirros image to xenserver using the steps above.

So what's the problem here? Could any one give any suggestions?

Thanks in advance!
