Hi, 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! -- Best Regards, Qin Jia Computer Science Cornell University -------------- next part -------------- An HTML attachment was scrubbed...
