[Engine-devel] IMPORTANT: engine_3.1 branch created
by Ofer Schreiber 21 Jun '12

21 Jun '12

Hey, I created the engine_3.1 branch on gerrit.ovirt.org, based on commit 6ef9f873ab88a35c8ec5afdcbbab7541c0d54c4e (masayag: "core: Remove trailing comma from network names list", pushed Wed Jun 20 10:16:57 2012 +0300). Any new critical bug fix, should be cherry-picked into engine_3.1 branch (by pushing the cherry-pick to refs/for/engine_3.1). If you have a critical fix merged after this commit, please make sure it's cherry-picked properly. Thanks, -- Ofer Schreiber oVirt Release Manager

[Engine-devel] [virt-node] VDSM as a general purpose virt host manager
by Saggi Mizrahi 21 Jun '12

21 Jun '12

There is an important discussion starting about the future of the VDSM API on vdsm-devel. If you want to be involved in the future of the VDSM API don't miss out and join vdsm-devel. To sign up go to https://fedorahosted.org/mailman/listinfo/vdsm-devel There growing need for a way to more easily reuse of the functionality of VDSM in order to service projects other than Ovirt-Engine. Originally VDSM was created as a proprietary agent for the sole purpose of serving the then proprietary version of what is known as ovirt-engine. Red Hat, after acquiring the technology, pressed on with it's commitment to open source ideals and released the code. But just releasing code into the wild doesn't build a community or makes a project successful. Further more when building open source software you should aspire to build reusable components instead of monolithic stacks. We would like to expose a stable, documented, well supported API. This gives us a chance to rethink the VDSM API from the ground up. There is already work in progress of making the internal logic of VDSM separate enough from the API layer so we could continue feature development and bug fixing while designing the API of the future. In order to achieve this though we need to do several things: 1. Declare API supportability guidelines 2. Decide on an API transport (e.g. REST, ZMQ, AMQP) 3. Make the API easily consumable (e.g. proper docs, example code, extending the API, etc) 4. Implement the API itself All of these are dependent on one another and the permutations are endless. This is why I think we should try and work on each one separately. All discussions will be done openly on the mailing list and until the final version comes out nothing is set in stone. If you think you have anything to contribute to this process, please do so either by commenting on the discussions or by sending code/docs/whatever patches. Once the API solidifies it will be quite difficult to change fundamental things, so speak now or forever hold your peace. Note that this is just an introductory email. There will be a quick follow up email to kick start the discussions. Don't forget to sign up to the vdsm-devel mailing list.

[Engine-devel] Questions about ovirt engine
by Shu Ming 19 Jun '12

19 Jun '12

Hi, I created a VM in my engine. And I found that every time I run the VM after shutdown, the VM uuid was changed to a different not while the VM itself was not changed including the VM name. Why doesn't engine keep the UUID for a VM and use the UUID every time the VM starts? How can I persistent my setting to a VM with "vdsClient", like the password set by the "setVmTicket" command? -- Shu Ming<shuming(a)linux.vnet.ibm.com> IBM China Systems and Technology Laboratory

[Engine-devel] 'deactivate' disk - what's the use case?
by Yaniv Kaul 18 Jun '12

18 Jun '12

I'm wondering what's the usefulness of having dual action of attach + activate to get a disk properly attached and working in a VM (and the deactivate and detach counterparts). The only reason I can think of is that we've annoyed the user by this useless dual action when working with storage domains in a data center for ages, and we wish to remain consistent and annoy the user in the disks scenario as well, but there may be a reason I'm not aware of. TIA, Y.

[Engine-devel] Version number changed to 3.1.0 (removing the _0001 suffix)
by Juan Hernandez 18 Jun '12

18 Jun '12

Hello, Please note that the suffix _0001 has been removed from the artifact versions and from the RPM version. This shouldn't be a problem, but if you find issues please let me know. Also take extra care when merging changes to any POM files, as you may be undoing the change for that particular POM file. Thanks in advance, Juan Hernandez -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif. Gorbea 3, planta 3ºD, 28016 Madrid, Spain Inscrita en el Reg. Mercantil de Madrid – C.I.F.

Hi everyone, please note that the original (SmartGWT-based) UserPortal application has been removed from oVirt repository, as part of patch [http://gerrit.ovirt.org/5317] This has no impact on the current UserPortal application, which is part of the standard oVirt Maven build. Please let me know if you have any questions. Thanks, Vojtech
