Hi Cinder folks, I am currently fixing the bugs related to booting the instance from the volume. I found there are bugs both in Nova and Cinder.
Cinder: https://bugs.launchpad.net/cinder/+bug/1159824 Nova: https://bugs.launchpad.net/nova/+bug/1191069 For the volumes created from the image, I propose to copy the reference image during the creation of the main image. For example, an image may refer to a kernel image and a ramdisk image. When we create a volume from this image, we only copied this one to the volume. The kernel and ramdisk images are still in glance, and the volume still refers to the kernel and ramdisk images. I think if an image has other reference images, the reference images also need to be copied to the volumes(kernel volume and ramdisk volume), and then set the volume referring to the kernel volume and the ramdisk volume. This feature will make booting from a volume completely independent of the existence of the glance image. Do you think we can firstly add this feature to cinder? Do folks have any comments on it? Thanks.
