Hi, Thank you very much for your reply ! But there are still some questions for me. Now I've come to the step where ironic partitions the disk as you replied. Then, how does ironic copies an image ? I know the image comes from glance. But how to know image is really available when reboot? And, what are the differences between final kernel (ramdisk) and original kernel (ramdisk) ?
