Probably you need to create qcow2 image out of iso image and then use that qcow2 to create VMs from Openstack. Follow the instructions similar to this: http://docs.openstack.org/image-guide/content/ubuntu-image.html From: Narayanan, Krishnaprasad [mailto:narayana at uni-mainz.de] Sent: Thursday, February 06, 2014 7:19 AM To: openstack at lists.openstack.org Subject: [Openstack] Error while booting VM Hallo all, Can I seek help for the problem described below? I have a VM running Ubuntu 12.04 in my OpenStack cloud and when it boots, I get an error message that says "Error: invalid magic number, error: You need to load the kernel first. Press any key to continue". Can I know how to make the VM boot? Thanks, Krishnaprasad -------------- next part -------------- An HTML attachment was scrubbed...
