The ability to clone an image to a volume was only recently added to cinder, so there is no automatic clone on boot in horizon yet. You will have to manually create a volume from an image and then boot from it.
For older versions of openstack, the instructions are here: http://docs.openstack.org/trunk/openstack-compute/admin/content/boot-from-volume.html In folsom you can skip the mount and copy step and just create a volume directly from an image: IMAGE_ID=f4addd24-4e8a-46bb-b15d-fae2591f1a35 cinder create --image-id $IMAGE_ID --display-name my-volume 10 VOLUME_ID=<uuid from above command> $ nova boot --image $IMAGE_ID --flavor 2 --key_name mykey --block_device_mapping vda=$VOLUME_ID boot-from-vol-test Vish On Oct 22, 2012, at 4:02 AM, Egoitz Aurrekoetxea Aurre <ego...@ramattack.net> wrote: > Good morning, > > I have noticed I was confused about the volume concept and booting from > volume.
