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).

[QE] oVirt 3.6.1 Hosted Engine test day
by Sandro Bonazzola 15 Dec '15

15 Dec '15

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.

AppErrors cleanup
by Allon Mureinik 15 Dec '15

15 Dec '15

Hi all, A recent bug [1] reported as part of the translation effort alerted me to the fact that we have a lot (and I mean a LOT - over 100 per file) of deprecated, unused keys in the various AppErrors files that serve no purpose and just take up space and waste translators time when they examine them. To make a long story short - I've just merged a patch to remove all these useless messages, and enforce via unit tests that EVERY key there should have a corresponding constant in the EngineMessage or EngineError enums. Many thanks to my reviewers! I know this was an tedious patch that couldn't have been too fun to review. -Allon [1] https://bugzilla.redhat.com/show_bug.cgi?id=1244766

by Yaniv Bronheim 15 Dec '15

15 Dec '15

Hi list, If you're not aware yet about Lago you should. This our engine to test functional flows over variant distributions for ovirt-engine and vdsm This project is currently maintained by dcaro but it will love to have more contribution in reviews, tests and more. If you want to follow it I encourage to join the mailing list lago-devel(a)ovirt.org and help with reviews if possible ([2]) You can also checkout following links for more info In [3] you can find full readme about how to use it to run ovirt-engine tests. should be intuitive and quick. If not, please raise [1] https://gerrit.ovirt.org/#/admin/projects/lago [2] https://gerrit.ovirt.org/#/q/project:+lago+status:+open [3] https://github.com/ovirt/lago Hope you'll find it interesting and Lago will get more attention by our community Greetings, -- *Yaniv Bronhaim.*
