New git repositories ovirt-engine-api-model, ovirt-engine-api-metamodel and ovirt-engine-api-explorer
by Juan Hernández 18 Dec '15

18 Dec '15

Hello, As part of the changes of the engine REST API for 4.0 two now components have been introduced: - The API model. This is the specification of the API, and it is currently part of the engine repository, in the backend/manager/modules/restapi/model directory. - The API metamodel. This is a set of tools that read the model and generate different artifacts from it, like the XML schema, the the JAX-RS interfaces, etc. It is also currently part of the engine repository, in the backend/manager/modules/restapi/metamodel. In order to support multiple versions of the specification inside the same engine the API model needs to be separated to a different git repository, its releases managed independently of the engine, and the artifacts uploaded to Maven central. The metamodel also needs to be separated to a different repository, and have its own relase cycle, and the artifacts uploaded to Maven central, as they will be required by the engine and by the generators of the SDKs. Thus I'm requesting the creation of two new git repositories in gerrit.ovirt.org to hold these components: ovirt-engine-api-model ovirt-engine-api-metamodel In addition version 4.0 will also include a web application used to explore the automatically generated reference documentation. This application is currently hosted here: https://github.com/jhernand/ovirt-api-explorer But I think it should be hosted in gerrit.ovirt.org, thus I'm also requesting the creation of another git repository: ovirt-engine-api-explorer All in call, can you please create these three git repositories and add me as maintainer, please? 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.

Making GWT UI build logs a bit less confusing
by Vojtech Szocs 17 Dec '15

17 Dec '15

Hi guys, I wrote https://gerrit.ovirt.org/#/c/50545/ and would like to hear your feedback. (Many times, people are confused by those [ERROR]'s which are not really errors.) Thanks, Vojtech

Merged UI infra patch
by Alexander Wels 16 Dec '15

16 Dec '15

Hi guys, I just merged [1] which removes all occurrences of the @ProxyEvent mechanism from the code base. As part of this patch I have to fix some Java generics issues with some sub tabs. I believe I fixed them all properly but I might have missed some. As part of this fix, now it will lazy load the code associated with sub tabs instead of loading all the code at once when you select an item in the main tab grid. This should result in a more responsive UI and less memory usage. If you see any kind of strange behavior in sub tabs let me know and I will see if I can fix it.

[ANN] oVirt 3.6.1 Final Release is now available
by Sandro Bonazzola 16 Dec '15

16 Dec '15

The oVirt Project is pleased to announce today the general availability of oVirt 3.6.1. This latest community release includes several new features, such as: * Ability to add/remove objects from the PM Proxy Preference list in the Power Management tab of Edit Host * Enhanced Cinder Provider -> Authentication Keys -> New/Edit dialog * Possibility to authenticate engine admin users to the JBoss JMX interface * Hosted Engine storage domain auto-import oVirt is an open-source, openly-governed enterprise virtualization management application, developed by a global community. You can use the oVirt management interface (oVirt Engine) to manage hardware nodes, storage and network resources, and to deploy and monitor virtual machines running in your data center. If you are familiar with VMware products, oVirt is conceptually similar to vSphere. oVirt serves as the bedrock for Red Hat's Enterprise Virtualization product, and it is the "upstream" project where new features are developed prior to their inclusion in Red Hat's supported product offering.

New VMStatus methods
by Shmuel Melamud 16 Dec '15

16 Dec '15

Hi! I've just posted the patch introducing new set of VM status checking methods. https://gerrit.ovirt.org/#/c/50590/ The methods are added to VMStatus class and delegated to VM class. The old methods are marked as deprecated and we plan to get rid of them soon. I highly recommend to use these methods everywhere and never to compare to VMStatus constants directly. There are methods to check for individual states and for meaningful sets - using them makes the code much more clear and understandable and it was the goal. If you cannot find a method that fits your needs, feel free to contact me, we can add it. Shmuel

New VM status functions - your comments?
by Shmuel Melamud 16 Dec '15

16 Dec '15

Hi! https://docs.google.com/a/redhat.com/spreadsheets/d/1yb-JdTAGh_4bOC6tL7KLz1… In the document above I've summarized the changes I plan to make to reorganize VM status checks in the Engine. The second page of the documents contains the list of the new functions and the statuses they will check. On the first page I've collected all the places I'm planning to change - class name, method name and line number. "New method" column is the new check that will be put in this place. Changing to new functions will often add/remove a state or two, that's why I'll be VERY pleased to see your comments. I've sorted the classes by topic, so it will be easy to look on those you're familiar with. Ask yourself questions: 1. If Up state is required, what about PoweringUp, PoweringDown, RebootInProgress? 2. If Up state is required, what about WaitingForLaunch? Paused? 3. What about migration? 4. What about hibernation? 5. If Down state is required, should it allow also ImageLocked and ImageIllegal? 6. If Down state is required, what about Suspended? Thank you in advance. Shmuel

QCOW2 support for base images vs GlusterFS support
by Christopher Pereira 16 Dec '15

16 Dec '15

Hi, 4:23 AM and this paradox is struggling my head... Can someone please confirm if oVirt supports QCOW2 *base* images? AFAIK, oVirt only supports QCOW2 for *snapshots* not base images. Base images must always be in RAW format and there is no way to create QCOW2 disks in Engine [1]. On the other hand, working with RAW images on a GlusterFS storage is inefficient because of [2]. in fact, sparse-files performance is unacceptable [3]. Please confirm, comment or ignore. [1] : https://bugzilla.redhat.com/show_bug.cgi?id=1282654 [2] : https://bugzilla.redhat.com/show_bug.cgi?id=1220173 [3] : For example.: A empty RAW disk image file with 2 TB virtual-size and less then 1 MB physical-size is treated by Gluster as a 2 TB physical-size file (TB's of useless zeros traversing the DataCenter's LAN during many hours).

Hi, oVirt 3.6.1 RC4 included latest bits allowing to auto import Hosted Engine storage domain within the Engine. In order to have a wider coverage of the Hosted Engine workflow we've scheduled a Hosted Engine test day for next week on Monday, December 14th. Please join us testing Hosted Engine with oVirt 3.6.1 RC4, both on a clean install and on an upgrade from 3.5 flow. Thanks, -- Sandro Bonazzola Better technology. Faster innovation.
