At last, give some tests and submit my patches for 'Rename storage volume' to upstream. Are my thoughts all right? Could anyone please give me some suggestions?

It doesn't hurt to destroy the object first if he wants to rename it. And I guess for most of the cases, it has to be destroyed first to let the new name take effect. E.g. For a domain, the qemu process has to be restarted to use the new name. Osier -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

We would have to move files (e.g. associated snapshots, monitor socket, logs, etc) and what if we fail somewhere in the middle of the process. We would have to perform a rollback. Sure, that's what it means to provide an atomic operation. You should not assume that dumpxml + define is more reliable though. For the QEMU/LXC drivers where XML is the canonical configuration, it may be reliable, but for VMWare / VirtualBox, the dumpxml + define pair will *loose* information for any native config declarations that libvirt does not understand. Their native APIs also already provide a rename capability, thus a libvirt rename API is unambiguously safer for those hypervisors. It is also much better from an access control POV, because the 'define' API is a highly privileged operation, whereas 'rename' is fairly low privilege. It is desirable to be able to give someone 'rename' permissions, without giving them 'define' permissions.

Hi all, After i read all comments from Danpb, Mprivozn, Osier, i find i should rephrase my project idea for Libvirt storage during GSOC 2013(Thanks for Stefan Hajnoczi. He let me know this key point).

Enthusiasm of the students to learn libvirt isn't the only consideration. The project mentors have to put non-trivial effort into GSoC and want to have some level of confidence that the project will result in a positive outcome for both the student the project. I think a project looking at adding 'rename' API support for all objects in libvirt has a high liklihood of success, since it is a clearly defined problem with easily measurable success criteria and a fairly unambiguous design to follow that will not require much debate. A project looking at capabilities has a much lower liklihood of success because it very focused on architectural design. Getting such design right requires significant knowledge of libvirt, and will require significant debate discussion by many parties on the list. Design discussions of this kind pay no attention to any external deadlines, that programs like GSoC have. I'm not saying a student couldn't write something, but I'm not confident that the result would be something we'd be prepared to merge, and by that benchmark could be considered a failure. I think GSoC projects should focus on something where the design is clearly defined upfront, and the task is mostly about learning the libvirt codebase getting a thorough implementation done.

While the work should definitely start with offline renames, there is also room for some additional scope such as online rename support for hypervisors such as ESX that might already provide such functionality natively and where the existing libvirt approach of dumpxml/define may be inadequate to expose the full hypervisor capability.

IMHO to do a good job on that design-wise requires someone with a very good understanding of libvirt architecture application needs. I understand. However, i think our Libvirt is developing so we should give more choices to learners who are very interested in some field of Libvirt.(Like me, i love the storage system of Libvirt very much). Maybe this is the essence of GSOC, isn't it? Actually, some student is not only interested in Libvirt but also wanna to join this community and contribute to this community forever. (Like me, i love the community because i can learn more knowledge from it.) I believe that interest is the best teacher. No matter how the problem is difficulty i will try my best to achieve it if i am very interested in it. Another key point is that GSOC just let students join the community and finish easy jobs firstly. GSOC wanna train more core developers for our community. If i can finish a job a bit difficulty, i can also accomplish it after GSOC continuously. All in all, i think you should not worry about this matter ;-). Hi all, After i read all comments from Danpb, Mprivozn, Osier, i find i should rephrase my project idea for Libvirt storage during GSOC 2013(Thanks for Stefan Hajnoczi. He let me know this key point). I find Osier and Mprivozn agree with the project named 'The capability support for storage' and Danpb just feel it is a bit difficulty for students to do, which i have given my feedback to explain. So i rephrase my project idea for Libvirt storage during GSOC 2013 like following. Project name: The capability support for storage driver. Summary: The capability support for storage driver (like virsh capabilities for the hypervisor drivers, e.g. what pool types it supports, what volume types each pool type supports, even may what operations/APIs the pool type support, ...etc). Sill level: Advanced. Osier said to me this is a deserved bug to fix so i think he may wanna be the mentor for this one, right? I could be if you want, but the question is which project you are focusing on? This one or the renaming APIs? And as far as I got from the wiki page, we generally don't want the student fails, and the renaming APIs work is much simpler than this one, and thus more possible to succeed in 12 weeks.

They can be just one project, as the work need to do for them is similar. Sure, they are a whole project for GSOC 2013 but separate ones. And not restricted to storage stuffs, if renaming API makes sense for storage volume, it makes sense for all other objects too, e.g. domain/network/interface/ nwfilter/secret/pool. What I'm thinking about is, the renaming is easy to implement for inactive objects, but for active ones, it's hard, even not possible, such as for a active domain, the domain name is refered by various places, if you change that, it will produce a big mess. Maybe i will have a try for all of them ;-) 4, Move volume from one pool to another. I will develop 'virsh vol-move xxx' option for virsh tool. Not sure it's deserved, the existing command create-vol-as/vol-clone can actually copy the volume from another pool. And after that, you can just remove the original volume. Perhaps having a virsh command to wrapper the the two APIs together is enough. Maybe we should have this virsh command to move volume from one pool to another one directly. -- Thanks Harry Wei -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

I suggest we can also add following ideas into this project. The capability support for storage driver (like virsh capabilities for the hypervisor drivers, e.g. what pool types it supports, what volume types each pool type supports, even may what operations/APIs the pool type support, ...etc). Deserved, but at beginner level too.

But IIUC, there are 3 levels (beginner, intermediate and advanced), so hopefully the ideas can land in one of them. Hi all, I've also got some ideas like following for GSOC 2013. Storage driver jobs. Currently, there is no Libvirt storage API to rename storage volume, storage pool, snapshot, etc. There is also no Libvirt API to move volume from one pool to another using libvirt API. Possibly those pools could have different backend (lvm, dir, ...). So i wanna finish these jobs for Libvirt during GSOC 2013. See following in details. 1, Rename storage volume. I will develop ' virsh vol-rename xxx' option for virsh tool. 2, Rename storage pool. I will develop 'virsh pool-rename xxx' option for virsh tool. 3, Rename snapshot. I will develop 'virsh snapshot-rename xxx' option for virsh tool. Not sure if you planned to request separate projects for these, but I don't think it's deserved for separate projects. They can be just one project, as the work need to do for them is similar. And not restricted to storage stuffs, if renaming API makes sense for storage volume, it makes sense for all other objects too, e.g. domain/network/interface/ nwfilter/secret/pool. What I'm thinking about is, the renaming is easy to implement for inactive objects, but for active ones, it's hard, even not possible, such as for a active domain, the domain name is refered by various places, if you change that, it will produce a big mess. 4, Move volume from one pool to another. I will develop 'virsh vol-move xxx' option for virsh tool. Not sure it's deserved, the existing command create-vol-as/vol-clone can actually copy the volume from another pool. And after that, you can just remove the original volume. Perhaps having a virsh command to wrapper the the two APIs together is enough. Well, currently, these are just good ideas for Libvirt GSOC 2013. I will give detail design plan for these stuffs according to the workflow of GSOC. Could anyone give me some suggestions?

You can begin thinking about ideas but please keep in mind that we are still in the very early stages of GSoC preparation. Google will publish the list of accepted organizations on April 8th. Then there is a period of over 3 weeks to discuss your project idea with the organization. In the meantime, the best thing to do is to get familiar with the code bases and see if you can find/fix a bug. Contributing patches is a great way to get noticed. There is always a chance that QEMU and/or libvirt may not be among the list of accepted organizations, so don't put all your eggs in one basket :).

But IIUC, there are 3 levels (beginner, intermediate and advanced), so hopefully the ideas can land in one of them. There should be enough work to do a 12 week project. 1) Virsh auto completion This is something I think will be very useful for nearly all libvirt users. I've proposed the idea a while ago and my sense is we have some consensus how this should work. But I am afraid this is more mechanical work than real programming one. I'm not sure how involved this will be. Perhaps it can be combined with related tasks to expand the scope to a 12 week project. 2) Storage driver jobs This is slightly advanced one. Currently, there's no way how to cancel an ongoing storage driver job. For instance, libvirt starts wiping huge file, however user at some point decides to cancel it. And for now, there is no way of doing that (other than just killing 'scub' binary to which we offload the work to). Things get complicated, if we want to share job acquiring code with qemu driver, and report progress (if operation itself is capable of it). Deserved. We lost this for long time, I filed the bug to track it before, but have not get time to do it yet: https://bugzilla.redhat.com/show_bug.cgi?id=830676 I agree, that storage driver job cancellation and progress reporting is a good project idea. The scope fits and it is a useful feature to support. They can start with scrub where libvirt has 100% control. Then, depending on their level of skill and time remaining, they can tackle the QEMU commands. The next step is to find concrete problems for the project description. This will allow students to begin looking into the libvirt code so they can come up with a plan for their work. It's best if you can point out the virsh commands or virt-manager methods that current block or are uninterruptible. Except this, glusterfs support is another thing I see we need to do sooner or later. I have ever had a glance at the gluterfs, as far as I see, setting up the basic is not complex, but fully support is an advanced job. Not sure how much work is necessary here but it could also be a good project idea for GSoC.
