[Openstack] Keystone integration in glance
We recently finished up functional tests for the keystone integration recently added to glance, and I wanted to send a quick description of the specifics for everyone's reference—could give people an idea of how to integrate with keystone for other projects. tl;dr version: The code added to glance performs integration with keystone, adds the concept of ownership to images, and allows images to be shared with others. Now, the details: First, glance is integrated with keystone. This requires adding a couple of sections to the glance-api.conf and glance-registry.conf configuration files and modifying the pipeline. (The plugin WSGI middleware pieces themselves are shipped with keystone.) This integration makes the username, tenant, and is_admin flag available. There is also an abstract concept of an owner--by default, this is the tenant, but a configuration option allows it to be switched to be the user name. The second piece is that all images now have an owner field (separate from image properties). The owner is based on that abstract concept of owner in the glance keystone integration--i.e., by default, images are owned by tenants, but flipping that configuration option makes them owned by individual users. Either way, the owner field of an image is set to the owner abstraction of the creating user and cannot be modified except by an admin. Also, the is_public flag that was already available for images is now interpreted relative to owner: if the image is owned by the authenticated user, it shows up in lists even if is_public is False, while other users can neither see nor access the image (with the exception of admins). There is one special behavior I implemented: if the owner of an image is set to nothing, the image is always accessible, but is_public determines whether the image is visible in lists. The point of this special behavior is to allow providers to publish alpha and beta images that they want some users to be able to use, but which they don't want to appear in lists of usable images. The third piece is image sharing. Images can be shared to other users; these third-party users cannot change the image, but they are able to see and use images shared with them, and may be delegated permission to further share images. Again, access controls are based on the owner abstraction. Now, the really long technical details: The is_public attribute already existed in images; the owner attribute has been added. It may not be changed; attempts to change owner are silently ignored (I wanted to allow the possibility that users take the image description, change a value, and PUT it back whole). The glance command line tool has been updated to allow admins to manipulate owner. Sharing is a little more complicated. There are a total of 5 operations added: listing who an image has been shared with (image members); listing images shared with someone; adding to or updating an entry in an image's sharing list (the image's membership list); replacing an image's membership list; and deleting an entry from an image's membership list. Retrieving an image's membership list is a GET to /images/{image_id}/members; the returned JSON entry looks like: {members: [ {member_id: MEMBER, can_share: SHARE_PERMISSION}, ... ]} Likewise, retrieving the list of images shared with a given owner is a GET to /shared-images/{member}, and the returned JSON looks like: {shared_images: [ {image_id: IMAGE, can_share: SHARE_PERMISSION}, ... ]} The entire membership list of an image may be replaced by doing a PUT to /images/{image_id}/members with a JSON body like the following: {memberships: [ {member_id: MEMBER, can_share: SHARE_PERMISSION}, ... ]} (Note that the can_share attribute is optional here; if not provided, old entries preserve their can_share setting and new entries default to False. Any entries not in the body will be removed.) Finally, individual entries can be added, updated, or deleted using PUT or DELETE requests to /images/{image_id}/members/{member}. For the PUT operation, the body is optional, for specifying the can_share setting of the membership: {member: {can_share: SHARE_PERMISSION}} If the body is not provided, existing entries have their can_share setting preserved and new entries have it default to False. Obviously, no body can be provided when deleting an entry with the DELETE operation. I should note that attempting to delete an image or update image attributes when you do not own the image will result in a 404 error, instead of a 403 error. The sharing operations listed above return 403, but the way glance is currently architected makes it more difficult to return a 403 for the image update/delete operations. I expect this to be addressed by future work. -- Kevin L. Mitchell

[Openstack] libvirt vs. Xen driver handling of local storage
Hey guys, We have a very annoying discrepancy between how local space is used in the xen driver vs the libvirt driver. I think it is vital that this is rectified before the Diablo release. We already have a few functional gaps between the drivers, but the fact that disks are partitioned completely differently between the two is very confusing to users. Bug is here: https://bugs.launchpad.net/nova/+bug/834189 The libvirt driver: * downloads the image from glance * resizes the image to 10G if it is 10G (in the case of a separate kernel and ramdisk image it extends the filesystem as well. In the case of a whole-disk image it just resizes the file because it doesn't know enough to change the filesystem) * attaches a second disk the size of local_gb to the image (when using block device mapping through the ec2 api, more swap/ephemeral disks can be attached as volumes as well) The XenServer driver (I'm less familiar with this code so please correct me if i am wrong here): * downloads the image from glance * creates a vdi from the base image * resizes the vdi to the size of local_gb The first method of resize to 10G and having separate local_gb is essentially the strategy taken by aws. Drawbacks of the first method: 1) The actual space used by the image is local_gb + 10G (or more if the base image is larger than 10G) which is inconsistent. 2) The guest has to deal with the annoyance of not having one large filesystem. It is easier for the user if they can just use all the space that they have without thinking about it. Drawbacks of the second method: 1) Limits cloud images to a particular format. We can't always guarantee that we can resize the image properly. We need to decide on a common strategy and use it for both hypervisors.

In the first case it is perfectly reasonable to have a whole disk image that is of a decent size for the base image, so you can get by just fine with the secondary attached disk if the resize does nothing.

Re: [Openstack] libvirt vs. Xen driver handling of local storage
Vish, I think Rackspace ozone/titan has some upcoming work to do for the resizing for xenserver that might close some of the gap. I think we need some options (flags) if we are to synchronize libvirt/xen. At some point, Rackspace also needs an API extension to support a couple different ways of handling resizes. Until we get there, we at least need an option to keep the xenserver code working as-is for now. I assume others need the current libvirt implementation to stay as well. That said, I think it's probably not too difficult to do the 'libvirt way' for Xen, but I don't know about it making diablo. Adding support into libvirt to do the 'xen way' should be easier, I'd think. But I'm the opposite of you, Vish. I don't know the libvirt layer as well. :) If we can FLAG the way it works... and make these options work in both libvirt/xen, I think we can all remain happy. - Chris On Aug 31, 2011, at 11:45 AM, Vishvananda Ishaya wrote: Hey guys, We have a very annoying discrepancy between how local space is used in the xen driver vs the libvirt driver.

I've heard this a couple times recently and it's a fine idea. That being said I'm not aware of anyone currently working on this. This would be a great thing to add for Essex and a great topic in general for the upcoming Design Summit in October. Is this something you want to work on?
