I am trying to create a linux VM inside of openstack, I have added the installer ISO as an image, and intend to install to a volume. Ceph is used for storage of both images and volumes. When I create the instance booting from the ISO image it starts up fine, and I am able to see the ISO's boot selection from the console. However, booting the installer greets me with Initramfs unpacking failed: write error. I don't quite know what would cause this, as I am very new to the openstack platform. I followed the base install guide for openstack on ubuntu, and added ceph storage to that with cinder. If there is any other information that would be useful in solving the problem, I can try to provide it.
