Our localization cycle is just kicked off and I would like to post our questions to this mailing list, just as I did for 3.4. It would be greatly appreciated if you could help us by answering questions, so that we can ensure accuracy of our translations, based on the context. Here is our first question. *File:***LocalizedEnums* **Resource ID:*** SELinuxMode___PERMISSIVE* **Strings:*** Permissive *Question:* Could someone explain to us how this appears in the Admin Portal? (we currently do not have a demo environment and cannot check it on the screen). Translators usually leave SELinux modes untranslated as they appear in the command line in English, however this string starts with the uppercase letter "P". We just wonder if this is used as descriptive or it refers exactly the "permissive" mode as shown in the terminal.

Announcing oVirt.js prototype
by Vojtech Szocs 17 Jun '14

------=_Part_23610907_1521630269.1403011303574 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hello everyone, in past few weeks, we've been working on JavaScript SDK for oVirt Engine. Today, I'm happy to announce the first prototype called oVirt.js :) Attached, there's an "sdk-testdrive" UI plugin which: - bundles oVirt.js prototype [ovirt.js] - contains test code for DataCenter object [plugin.js] To install this plugin, simply copy (or symlink) sdk-testdrive.json file and sdk-testdrive-resources directory under /usr/share/ovirt-engine/ui-plugins. Following is a quick recap of test code exercising oVirt.js. To add new DataCenter: // Obtain DataCenter resource collection. // Resource collection is a handle to work with RESTful objects. var dcColl = ovirt.api.datacenters; // Obtain "add DataCenter" operation. // Operation is a reusable, uhm, operation, backed by HTTP request. // You can run the same operation multiple times, if necessary. var addOp = dcColl.add({ name: 'test-dc', local: false }); // Register result handler and run the operation. addOp.success(dcAddedCallback).run(); // Example of operation result handler that receives a single resource. function dcAddedCallback (dc) { console.log('Added: ' + dc.data().name); } In dcAddedCallback function shown above, "dc" is a resource object, representing a handle to work with RESTful DataCenter object. It provides access to underlying resource data: var dcDataObj = dc.data(); // Get var dcName = dcDataObj.name; var dcDesc = dcDataObj.description; // Set multiple properties at once ... dc.data({ name: 'test-dc-updated', description: 'test' }); // ... or one by one dcDataObj.name = 'test-dc-updated'; dcDataObj.description = 'test'; It also gives access to nested collections (if any) and supported actions (if any): // Obtain Cluster resource collection for given DataCenter. var dcClusterColl = dc.clusters; oVirt.js is currently only 445 lines of code, yey :) we're not using any code generation at this point, we're simply relying on HATEOAS [1] principle of REST and dynamically augmenting resource objects with nested collections and supported actions, which are part of resource representation. [1] http://en.wikipedia.org/wiki/HATEOAS I feel we'll eventually come to a point where code generation can be useful, but for now, we're trying to keep things small and simple. oVirt.js currently uses Lo-Dash library [2] containing various utility functions. I think that Lo-Dash is great because it makes working with JavaScript a bit easier. [2] http://lodash.com/ Overall, oVirt.js will be self-contained, which means there will be no additional dependencies from JavaScript perspective. Using oVirt.js in HTML page will be as simple as this: <script src="ovirt.js"></script> This means that (build-time) dependencies such as Lo-Dash will be inlined into resulting oVirt.js build. We're also planning to provide minified version + Source Maps for better debugging. oVirt.js is planned to be usable NOT ONLY in web browsers. In fact, there's "ovirt.svc" namespace containing services used by oVirt.js API implementation. You (or any 3rd party extension) can override these services to achieve SDK portability for given runtime environment. In other words, I'd love to see oVirt.js used also with Node.js :) Finally, an important thing to mention - oVirt.js requires AT LEAST ECMAScript 5.1 compliant environment. All modern browsers support ES5, including IE9+. Unfortunately, IE9 doesn't support ES5 Strict Mode, but that's not that big of a deal. I'll send some more emails outlining implementation design and also how to manage source control & distribution of oVirt.js.

----- Forwarded Message ----- From: "Paolo Bonzini" <pbonzini(a)redhat.com> To: "Libvirt" <libvir-list(a)redhat.com> Sent: Monday, June 16, 2014 12:08:22 PM Subject: [libvirt] KVM Forum 2014 Call for Participation ================================================================= KVM Forum 2014: Call For Participation October 14-16, 2014 - Congress Centre Düsseldorf - Düsseldorf, Germany (All submissions must be received before midnight July 27, 2014) ================================================================= KVM is an industry leading open source hypervisor that provides an ideal platform for datacenter virtualization, virtual desktop infrastructure, and cloud computing. Once again, it's time to bring together the community of developers and users that define the KVM ecosystem for our annual technical conference. We will discuss the current state of affairs and plan for the future of KVM, its surrounding infrastructure, and management tools. Mark your calendar and join us in advancing KVM. http://events.linuxfoundation.org/events/kvm-forum/ Once again we are colocated with the Linux Foundation's LinuxCon Europe, CloudOpen Europe, Embedded Linux Conference (ELC) Europe, and this year, the Linux Plumbers Conference. KVM Forum attendees will be able to attend LinuxCon + CloudOpen + ELC for a discounted rate. http://events.linuxfoundation.org/events/kvm-forum/attend/register We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2014. http://events.linuxfoundation.org/cfp Suggested topics: KVM/Kernel - Scaling and optimizations - Nested virtualization - Linux kernel performance improvements - Resource management (CPU, I/O, memory) - Hardening and security - VFIO: SR-IOV, GPU, platform device assignment - Architecture ports QEMU - Management interfaces: QOM and QMP - New devices, new boards, new architectures - Scaling and optimizations - Desktop virtualization and SPICE - Virtual GPU - virtio and vhost, including non-Linux or non-virtualized uses - Hardening and security - New storage features - Live migration and fault tolerance - High availability and continuous backup - Real-time guest support - Emulation and TCG - Firmware: ACPI, UEFI, coreboot, u-Boot, etc. - Testing Management and infrastructure - Managing KVM: Libvirt, OpenStack, oVirt, etc. - Storage: glusterfs, Ceph, etc. - Software defined networking: Open vSwitch, OpenDaylight, etc. - Network Function Virtualization - Security - Provisioning - Performance tuning =============== SUBMITTING YOUR PROPOSAL =============== Abstracts due: July 27, 2014 Please submit a short abstract (~150 words) describing your presentation proposal. Slots vary in length up to 45 minutes. Also include in your proposal the proposal type -- one of: - technical talk - end-user talk Submit your proposal here: http://events.linuxfoundation.org/cfp Please only use the categories "presentation" and "panel discussion" You will receive a notification whether or not your presentation proposal was accepted by Aug 20th. Speakers will receive a complimentary pass for the event. In the instance that your submission has multiple presenters, only the primary speaker for a proposal will receive a complementary event pass. For panel discussions, all panelists will receive a complimentary event pass. TECHNICAL TALKS A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, it should focus on the work that needs to be done or the difficulties that haven't yet been solved. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups.

Question/thoughts about our engine logging framework
by Yair Zaslavsky 16 Jun '14

16 Jun '14

Hi all, During my recent work on AAA, I was suggested by Juan Hernandez to use slf4j logging framework which serves as a facade for other logging frameworks (including java utils logging which is now used by jboss), log4j and others. I have accepted Juan's offer, and then when looking at our LogFactory class I have noticed we use commons logging. Several thoughts/questions - A. Why continue use our own wrapper as slf4j is already a facade. b. I think we should move cross java code to slf4j. What do you think on this point? Some reading material - http://javarevisited.blogspot.com.au/2013/08/why-use-sl4j-over-log4j-for-lo… http://stackoverflow.com/questions/3222895/what-is-the-issue-with-the-runti… Yair

Say Hello to the oVirt Engine Virtual Appliance
by Fabian Deutsch 16 Jun '14

16 Jun '14

Hey, one of the things on the list for oVirt 3.5 was the oVirt Virtual Appliance. Huh, what’s that? You might ask. Well, imagine a cloud image with oVirt Engine 3.5 and it’s dependencies pre-installed, and a sane default answer file for ovirt-engine-setup. All of this delivered in an OVA file. The intention is to get you a running oVirt Engine without much hassle. Furthermore this appliance can be used in conjunction with - and is actually intended for - the Self Hosted Engine feature, and the upcoming oVirt Node Hosted Engine plugin. More informations and links about the appliance and how to build it can be found here: http://dummdida.tumblr.com/post/88944206100/say-hello-to-the-ovirt-engine-v… Testing it with hosted engine is the next step. Greetings fabian

All, I pulled the latest vdsm from master and noticed that build is failing. Here is the patch that causes the failuer: http://gerrit.ovirt.org/#/c/28226 and looking at jenkins comments I can see that jenkins was failing with the same reason: http://jenkins.ovirt.org/job/vdsm_master_storage_functional_tests_localfs_g… Thanks, Piotr

Small note on workarounds in UI code
by Vojtech Szocs 13 Jun '14

13 Jun '14

Hi guys, recently, we've merged a small patch [1] that adds some info on notable (in this case, GWT-Platform framework related) workarounds via comments that look like this: // TODO-GWT: description goes here If you find yourself working around some GWT or GWT-Platform issue, please add a comment like above with some brief description, i.e. link to GWT(P) issue tracker and maybe also short summary of the workaround. In future, when upgrading to newer GWT/P versions, this should aid us in reviewing existing code and reducing the risk of potential issues due to the upgrade. (Ideally, workarounds shouldn't be needed assuming relevant issues are fixed in newer versions; in the worst case, those workarounds might pass compilation but will actually not work or even break stuff.)

virtio-scsi
by Marcus White 12 Jun '14

12 Jun '14

Hello I had some basic questions, was asking them on the kvm list but it probably makes more sense here:) The questions are about virtio-scsi. I would appreciate any help. 1. Is virtio-scsi via QEMU a zero copy operation from guest to disk? The vhost-LIO as I understand it is zero copy, wasnt sure about QEMU. With the VM and the QEMU thread part of the same process, it would be good to know the flow and where the copies occur, if they do. 2. When the block layer underneath QEMU(assuming the QEMU does talk to the block device and not sg, for example), if an error code comes in, is it converted to a SCSI response before being passed to the guest? 3. Are there any other performance tweaks that would help in both the QEMU case and the LIO case? Thanks in advance:) MW

Posting to ovirt-devel will help in having people to review your patches. I did "git blame" on the file you changed in http://gerrit.ovirt.org/28113 and added those who already changed that file for reviewing the patch. > Who decides which oVirt version will include this code or if this code will be included or needs adaptions (I only know that a certain score in gerrit > is required and some developers are allowed to rate a commit)? > > I'm aware that my commit isn't fancy at all and there's no need for any priority, but just want to know what's the right workflow in case I have more > time to work on some bugs... > > I guess these questions could be interesting for users (basically for users who are not familiar with a professional development setup/workflow > including gerrit like me) who want to work on the bugs in june edition as well... I agree. You did everything right since now: - opened a bz - pushed a patch referencing it - added the gerrit reference to bugzilla what you just miss is adding other people for reviewing the patch. Oved Ourfali already set whiteboard to virt, so this is a virt team patch and virt team maintainers will merge your patch once it's ready. Itamar Heim also reviewd the bug you pushed and set target release to 3.5.0. Now you just need to wait for other developers to review the patch and maintainer to merge it. If there will be comments on your patch a new version of the patch may be needed (just amend the patch and push again with the same Change-ID) and it will be reviewed again. you can find more info on gerrit here: https://gerrit-review.googlesource.com/Documentation > > > Thanks, > René > > > On 06/12/2014 04:11 PM, Sandro Bonazzola wrote: >> Hi, >> have you got some free time and do you want to get involved in oVirt integration? >> After the success of first edition we're now proposing this again. >> Here are a couple of bugs you can hopefully fix in less that one day or you can just try to reproduce providing info: >> >> Bug 1091651 - Misleading error message when first host cannot be reached during hosted-engine deployment >> Bug 1080823 - [RFE] make override of iptables configurable when using hosted-engine >> Bug 1065350 - hosted-engine should prompt a question at the user when the host was already a host in the engine >> Bug 1097635 - ovirt-hosted-engine-setup fails with Modules libvirt contains invalid configuration >> >> Is this the first time you try to contribute to oVirt project? >> You can start from here [1][2]! >> >> [1] http://www.ovirt.org/Develop >> [2] http://www.ovirt.org/Working_with_oVirt_Gerrit >> >> -- Sandro Bonazzola Better technology.

Entity names in DB scripts

Hi all, I have a feeling there is some inconsistency in using entity names in the DB scripts. For example, should we use Host or VDS? I am not talking about existing tables or columns but about new ones (and new stored procedures). I am quite sure I saw patches containing both approaches. Yair

[ANN] oVirt 3.4.2 Release is now available
by Sandro Bonazzola 10 Jun '14

10 Jun '14

The oVirt development team is pleased to announce the general availability of oVirt 3.4.2 as of Jun 10th 2014. This release solidifies oVirt as a leading KVM management application and open source alternative to VMware vSphere. oVirt is available now for Fedora 19 and Red Hat Enterprise Linux 6.5 (or similar). This release of oVirt includes numerous bug fixes. See the release notes [1] for a list of the new features and bugs fixed. The existing repository ovirt-3.4 has been updated for delivering this release without the need of enabling any other repository, however since we introduced package signing you need an additional step in order to get the public keys installed on your system if you're upgrading from an older release. Please refer to release notes [1] for Installation / Upgrade instructions. Please note that mirrors will need a couple of days before being synchronized. If you want to be sure to use latest rpms and don't want to wait for the mirrors, you can edit /etc/yum.repos.d/ovirt-3.4.repo commenting the mirror line and removing the comment on baseurl line. A new oVirt Node and oVirt Live ISO will be available soon[2].

Hi guys, following is a summary of today's Gamification session. More details can be found on Gamification etherpad [1]. * Eyal gave an overview of oVirt Gamification initiative and its projects * Vojtech went really quickly through Space Shooter UI plugin * Vojtech walked through main parts of ProgressBar UI plugin source code Next action items: - implement service to retrieve "event" info from Engine - implement service to load achievement definitions and compare them with "event" info - modify main tab to show real data (instead of dummy data) - achievement categories and their respective progress - list of achievements, visually distinguished by their status (completed/locked/etc.) Future action items: - use Grunt to automate common development & build tasks - provide "badges" (round icons) for different achievements -- any volunteers? :) - think of logical scenarios (levels) that group multiple achievements * YamakasY pointed out that it would be nice to have better integration for popular frameworks like AngularJS, establishing common development tools/libraries, sharing knowledge and experience with others Feel free to add anything I might have missed :) [1] http://etherpad.ovirt.org/p/gamification Regards, Vojtech

Hi List, This is the design for NUMA-support oVirt Scheduler integration; I'll add 3 policy unit modules (#) as described in following document: (1) Filter Module: NUMA_HostFilter: If the VM has NUMA vNodes/pinning configured, and the rule can't be accommodated on the host, it'd filtered. NOTES: * pin2host filter should make sure the filter gets a single host. the filter should be transparent to specific hosts. * not sure we'll want to add this filter in first phase to all cluster/scheduling policies; @Doron? Weights Modules: (2) even_dest_NUMA Should "even distribute" weights (scores) according to: * Available memory on nodes * Numatune memory mode (strict/preferred/interleave) * Autonuma/pinned NUMA (3) power_saving_NUMA (added to power_saving cluster/scheduling policy) * same as even_dest_NUMA with opposite weights. I'd appreciate any comment or suggestion. Once approved by you, I'll update the feature page and upload a patch for review. Thanks, Gilad.

GetCaps for jsonrpc
by Piotr Kliczewski 08 Jun '14

08 Jun '14

Hi all, I would like to see whether there are any suggestions how we can provide information like: - lastClient - lastClientIface - network interface on which client connected In the code prior to jsonrpc changes every time new request (new connection) was received clientIF threadLocal was updated with client information. This code was implemented in xml binding and now we need to provide similar information for jsonrpc. There is difference that we keep connection open for jsonrpc so we can't provide behavior as described above. We can update client information when connection is established. Is that OK or are there any suggestions how to update this information? Thanks, Piotr
