Missing admin permissions.
by Alexander Wels 21 Jan '16

21 Jan '16

Hi, Somewhere during master upgrades somehow my admin@internal did not get permissions to create VMs. Its is compiling about no permissions to assign a CPU profile. Its been a while since I tried creating a VM. Can any one point me to what is missing and how to fix it? This is the error in the log: 2016-01-18 15:59:46,843 INFO [org.ovirt.engine.core.bll.AddVmCommand] (default task-56) [a6fd12b] Lock Acquired to object 'EngineLock: {exclusiveLocks='[xxxx=<VM_NAME, ACTION_TYPE_FAILED_OBJECT_LOCKED>]', sharedLocks='[00000000-0000-0000-0000-000000000000=<TEMPLATE, ACTION_TYPE_FAILED_TEMPLATE_IS_USED_FOR_CREATE_VM$VmName xxxx>]'}' 2016-01-18 15:59:46,893 WARN [org.ovirt.engine.core.bll.AddVmCommand] (default task-56) [] Validation of action 'AddVm' failed for user admin@internal.

[ATN] RESTAPI specification moving to a separate git repository
by Juan Hernández 21 Jan '16

21 Jan '16

Hello, The specification of the RESTAPI (a.k.a. the model) and the tools that process it (a.k.a. the metamodel) have been moved to separate git repositories: Model: git clone https://gerrit.ovirt.org/ovirt-engine-api-model https://github.com/oVirt/ovirt-engine-api-metamodel Metamodel: git clone https://gerrit.ovirt.org/ovirt-engine-api-metamodel https://github.com/oVirt/ovirt-engine-api-model Currently I'm manually keeping these repositories in sync with the ovirt-engine repository, but I will very soon remove all this code from the ovirt-engine repository: restapi: Move model to separate repository https://gerrit.ovirt.org/51519 This means that once the above patch is merged, which will be very soon, probably this week, when you need to do changes to the specification of the RESTAPI, you will need first to prepare a patch for the ovirt-engine-api-model, submit it, review it, etc. Once that patch is merged I will do a new release of the model. Then you will need to update the root POM of the engine to use the new version of the model, for example: - <model.version>4.0.1</model.version> + <model.version>4.0.2</model.version> And adjust the engine to work with the new version of the model. As you will probably want to do these changes and test them before publishing anything, or asking for any review, I'd suggest the following process: 1. Checkout the model project: $ git clone git://gerrit.ovirt.org/ovirt-engine-api-model 2. Check the version number in the root POM. It should be a SNAPSHOT version, unless you explicitly checkout from a tag. For example, currently it is 4.0.2-SNAPSHOT. 3. Make your changes to the model, and then install it to your local Maven repository: $ mvn clean install 4. Add to your $HOME/.m2/settings.xml a profile that is activated automatically and that changes the value of the "model.version" property used by the engine: <activeProfiles> <activeProfile>myprofile</activeProfile> </activeProfiles> <profiles> <profile> <id>myprofile</id> <properties> <model.version>4.0.2-SNAPSHOT</model.version> </properties> </profile> </profiles> 5. Make your changes to the engine, and build it as usual, it will your modified version of the model. 6. Publish/review the changes to the model. 7. Wait for the new model release. 8. Publish/review the changes to the engine, including the change of the model version in the root POM. Note that you can publish/review these changes without waiting for the new model release, but the Jenkins test will fail. Note also that changes to the model will need to be properly documented in order to be accepted. There are some instructions on how to document the model here: https://github.com/oVirt/ovirt-engine-api-model/blob/master/README.md All these changes affect only the master branch, nothing changed in these regards in the 3.6 branch.

Alpha version of the Ruby SDK ready for use
by Juan Hernández 20 Jan '16

20 Jan '16

Hello, Version 4 of oVirt will include a new Ruby SDK. It is currently in "alpha" status, but I think it is already usable. It is available from "rubygems.org": https://rubygems.org/gems/ovirt-engine-sdk You can install it as usual: $ gem install ovirt-engine-sdk There are examples of how to use it in the source code itself: https://github.com/oVirt/ovirt-engine-sdk-ruby/blob/master/sdk/README.md https://github.com/oVirt/ovirt-engine-sdk-ruby/tree/master/sdk/examples Any feedback is welcome, via this list, reporting bugs: https://bugzilla.redhat.com/enter_bug.cgi?product=ovirt-engine-sdk-ruby Or sending patches to gerrit: $ git clone git://gerrit.ovirt.org/ovirt-engine-sdk-ruby.git Regards, Juan Hernandez -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.

Vdsm sync 19/1
by Yaniv Bronheim 20 Jan '16

20 Jan '16

Hi all, (Participated: Piotr, Francesco, Adam, Nir, Edy and I) We discussed about the following topics: Python3 - terminating contextmanager is ready https://gerrit.ovirt.org/51407 - this allows us to remove deathSignal usages and safely kill processes on failures. Francesco already covered one location (https://gerrit.ovirt.org/#/c/52349/) this week I hope we'll *start* the work to cover the rest of the code as follow: vdsm/storage/mount.py vdsm/storage/iscsiadm.py vdsm/storage/imageSharing.py vdsm/storage/hba.py vdsm/storage/blockSD.py vdsm/v2v.py If any gaps or dependencies are raised I asked to state it in python3 work sheet ( https://docs.google.com/spreadsheets/d/180F-C1jU54ajUn7TuR-NwrKRZY1IiZI1Z8U…) and we'll discuss it in next call. next will be to remove all deathSignal usages - currently there are redundant place where its being used that can be removed today: lib/vdsm/qemuimg.py vdsm/storage/curlImgWrap.py vdsm/storage/storage_mailbox.py vdsm/storage/misc.py vdsm/API.py Hopefully patches for that will be posted during the week. Next step will be to use Popen where cpopen is not available ( https://gerrit.ovirt.org/48384) and we'll move forward with migrate more tests to python3. - Vdsm communicate - we did a little summary about what was explored and what we want to have. It was only a discussion to see where we're heading. External Broker - In the past we checked Cupid (IMQP) and ActiveMQ (STOMP). In cupid we found many bugs and gaps, we thought about using only the client of it for point to point communication, but then found it too complex. actionMQ is in java and found to be too slow and consume a lot of memory so we thought about having only one instance in cluster, or maybe run it in external host that doesn't run vdsm, or put it with the engine host - for that we will need to change all "host lifecycle" that we have today so we left it as well (piotr, fill me up if I missed something) We have implementation for "mini borker" as part of vdsm which perform what we need to run it as external process to vdsm and forward messages to clients. there are alternatives as ZeroMQ that we can explore. Bottom line - we want to approve the communicate inside the host, between vdsm to other services such as supervdsm, mom and maybe later we'll split the current implementation of vdsm to more services that will run in parallel (such as vm monitoring, vdsm-storage and so on. For that we can use dbus, multiprocessing(uds), or some kind of a broker. This leaded us to talk about service separation which we want to design soon. - Vdsm contract - Piotr sent yaml schema plan in https://gerrit.ovirt.org/#/c/52404 - please ack that you agree with the concept. Piotr moves on with that and start to migrate all verbs to that form. For next version we shell have both types of schema available, and start to add new verbs and events structures in the new yaml format. - Exceptions - Nir raises that we should define Virt specific exceptions - Francesco can elaborate about the plans next week. - Network updates - Edy checks how to improve network configuration time. Currently vdsm modifies ifcfg files, which after changing them it takes time for the update to catch. Interesting call guys, I encourage more developers to participate, listen and influence vdsm 4.0 directions. See you next week. -- *Yaniv Bronhaim.*

vdsm] tag and branch ovirt 3.6.2 RC3

Hi, Sorry for the short notice of this email. the state of branch ovirt-3.6 is as follows tag sha subject bug target release ---------------------------------------------------------------------------------------------------------------------- de54e59 virt: Don't expose GuestAgent.guestInfo directly 1295428 3.6.3 83c4ac8 supervdsm: failed validateAccess leaves pipes open 1271575 3.6.3 37bda50 vm: safer handling of conf in restore 1296936 3.6.3 57b1814 virt: safer handling of migration parameters 1296936 3.6.3 9b29ddd lun: Serial attr should not passed to libvirt for lun disks. 1291930 3.6.2 <<<< 7b94531 migration: use context manager for semaphore 1296936 3.6.3 508b2fd virt: Correct epoll unregistration usage in vmchannels 1226911 3.6.3 68a1b69 virt: Set cloexec flag on channel sockets 1226911 3.6.3 4.17.17 505026d spec: require libvirt to fix hotplugging So, for the next tag the plan is to 1. branch out ovirt-3.6.2 from tag 4.17.17. This branch is expected to be short-lived (basically only for this RC). 2. apply commit 9b29ddd only 3. tag 4.17.18 from branch ovirt-3.6.2 I see we have only two patches in queue for ovirt-3.6 https://gerrit.ovirt.org/#/c/52346/ https://gerrit.ovirt.org/#/c/52348/ Do we need them in this build? Should we require another 3.6.2 build, backports will be needed ALSO on branch ovirt-3.6.2. Will start implement the plan before lunch if noone objects.

[vdsm] New schema format proposal
by Piotr Kliczewski 19 Jan '16

19 Jan '16

I would like to propose new format for schema that we use in vdsm. I started to work on a patch [1] where I explore how the new file should look like. I have couple of goals which I would like to achieve by doing this transformation: 1. I would like to use this file to verify engine code. Currently we check only vdsm which leads to compatibility issues. 2. I would like to base new jsonrpc based replacement for vdsClient on it. I want to create dynamic client which would use new format (description used as help when calling verbs) 3. Simplify Bridge.py 4. Extend the schema to add events 5. Explore ideas around api evolution and contract definition. Once we agree on the format I will work on script which will translate one format to the other. Thanks, Piotr [1] https://gerrit.ovirt.org/#/c/52404

oVirt Node Next - Sprint 2 Summary
by Fabian Deutsch 19 Jan '16

19 Jan '16

Hey, during our second sprint, lasting 3 weeks, ending on January 15, the Node team worked on the following items: Add ovirt-release-host-node --------------------------------------- This subpackage of ovirt-release now has all teh dependencies which are expected to be available on node. In addition to vdsm, this package also depends on cockpit and imgbased. In addition this file carries systemd presets, to enable the relevant services, it also provides the firewalld configuration of Node. It also set's the VARIANT fields in teh os-release file to identify node in a non-invasive way. https://gerrit.ovirt.org/gitweb?p=ovirt-release.git;a=tree;f=ovirt-release-… Add branding to ovirt-release-host-node -------------------------------------------------------- This is part of the next sprint but already completed: The release file now also provides oVirt branding for cockpit! https://gerrit.ovirt.org/gitweb?p=ovirt-release.git;a=tree;f=ovirt-release-… Move imgbased to gerrit ----------------------------------- imgbased is the component taking care of the image management on node. Previously it was hosted on github, now it's on gerrit: https://gerrit.ovirt.org/gitweb?p=imgbased.git Yaml-ize imgbased and ovirt-node-ng jobs ------------------------------------------------------------ The ovirt-node-ng repository holds the image recipe (and nothing else), this repo was created adn yaml-ized and is building on jenkins. The job for imgbased was also yamlized and is alos building on jenkins: http://jenkins.ovirt.org/job/imgbased_master_build-artifacts-el7-x86_64/ http://jenkins.ovirt.org/job/ovirt-node-ng_master_build-artifacts-fc23-x86_… Next ------- In the next sprint - 3 - the team will focus on further stabilizing the jenkins builds, creating the update rpm and creating the required disk layout during installation. The bottom line is that the ovirt-node-ng image is now regularly build in u/s - still a bit flaky, but it's there. The squashfs can be used for installing node, as described here: http://lists.ovirt.org/pipermail/devel/2016-January/012073.html On behalf of the Node team fabian

Topic for next Vdsm call - 19.1
by Yaniv Bronheim 18 Jan '16

18 Jan '16

Things I plan to raise. feel free to add more 1. Plans to handle async processes without using death signal. 2. Vdsm messaging - I'll ask Piotr to elaborate about infra plans for that topic (what about the external broker plans? any standard plan to communicate with vdsm? such as for supervdsm and mom). 3. Contract for events and new apis - where it stands. 4. py.test - If someone can pick up the migration to py test -- *Yaniv Bronhaim.*

Subject: Looking for advice regarding user portal development.
by Thomas Shaw 18 Jan '16

18 Jan '16

Evening all, I'm a student from the UK, currently studying Bsc (Hons) Computer Forensics & Security, looking for a bit of advice regarding front-end development for the oVirt user portal. For my final year project I’m going to be extending the current user portal to produce a user interface that fits the needs of Computer Security education. I want to create an interface that supports the workflow of a tutor configuring one to many virtual machines / networks for a scenario based lab session. The project will involve developing two different interfaces depending on whether a student or tutor is logged in. The project is going to be based on a paper that was presented in the UK at the first Cybersecurity Education and Training conference as part of the Vibrant Workshop, and is available in full here: http://z.cliffe.schreuders.org/publications/VibrantWorkshop2015%20-%20An%20… The tutor portal will have an avenue for tutors to upload images and a way to group templates of virtual machines for students to clone. The student portal will have one webpage with a list of their owned VMs on the left, like the current user portal, and all lab VM templates on the right organised/grouped by lab. Students will be able to clone a VM or group of VM's from the right with a couple of clicks at most. I'm planning on forking the user-portal code and making changes here. I want a different interface to appear for the students and the tutors. Initial thoughts were to do this based on the 'Role' concept within oVirt - I plan on creating 2 new user group’s with predefined roles, Student and Tutor, and having the tutor-only functionality appear on an additional tab which only appears if the logged in user has the Tutor role. We have a powerful development server at university which is currently running oVirt 3.6 with 3 nodes. As of right now I've set up the engine development environment on Fedora 23. I'm still getting familiar with the code and build process and have not yet deployed a build to the server. It is my hope and intention that any work I produce will be of value to the greater community and will open source all work. I would really appreciate any input / advice in developing for the user portal and hope to produce something make my code changes more likely to be accepted upstream. Thanks for reading, Thomas Shaw

[ANN] Team in Whiteboard is not more, long live oVirt Team custom field.
by Yaniv Dary 18 Jan '16

18 Jan '16

Hi All, For a long time now we have been using the whiteboard free-text field to set the team that owns each ticket in Bugzilla. This causes several issues: - The usage was not documented. - We had issue reporting on that field. - People can make mistakes setting it (mis-spelling the team for example). Today Bugzilla team has completed setting oVirt Team field for all open bugs (NEW-> VERIFIED). From today we will be moving to using it. The documentation for this field is updated in Bugzilla, so if you are not sure on what team to set the ticket, click on the field itself and you will have a detailed help page. Please update all queries to use it! It should be easy to do so by changing the field you search on from 'Whiteboard' to 'oVirt Team'. Next Tuesday (26/01/16) I will request removal of all whiteboard team values. Please make sure to fix you queries beforehand. Thanks!

oVirt engine 4.0 will require WildFly 10 / EAP 7
by Martin Perina 18 Jan '16

18 Jan '16

Hi, we are going to merge patches which drop EAP 6 support [1] and require WildFly 10 / EAP 7 [2] for oVirt engine master on Monday January 18th at 10:00 CET. This is a huge step as we will finally be able to use all new features provided by WildFly 10 (J2EE 7, Java 8, RESTEasy 3, ActiveMQ Artemis, Hibernate 5, ...). Upgrade of code base to use those new features will be done incrementally, for example this patch [3] cleans up our CDI related code and upgrades to CDI 1.2. So on Monday please upgrade WildFly packages on your development machines to: ovirt-engine-wildfly-10.0.0 ovirt-engine-wildfly-overlay-10.0.0 and rebase your patches on top of latest master. To ease backporting of patches to oVirt 3.6 we have already merged patches which made oVirt 3.6 compatible with WildFly 10, but please bear in mind that oVirt 3.6 have to be compatible with EAP 6 and there are no plans to upgrade it to WildFly 10! Please contact me or other members of infra team if you have any issues with this upgrade. Thanks Martin Perina [1] https://gerrit.ovirt.org/48208 [2] https://gerrit.ovirt.org/48209 [3] https://gerrit.ovirt.org/48305

No more "vds group" in master code , instead please use "cluster"
by Eli Mesika 17 Jan '16

17 Jan '16

Hi I have merged today this patch[1] to master. The code from historical reasons uses both "vds group" and "cluster" for a cluster entity. This makes the code not-clear, non-readable and hard for beginners (to find for example SPs that handle clusters , or all code related to a cluster operation) This also makes our logging and error messages using sometimes "vds group" and sometimes "cluster" to relate to the same entity. Worse than that, new code written sometimes introduce a mix of both terms. Patch[1] renames "vds group" to cluster all over the code. This renaming covers all engine code including Class names Variables Comments Logging Error messages Database tables,views, columns and SPs including all kinds of keys and constrains Please do not use from now on the term "vds group" (all its variants (VdsGroup, vdsGroup, vds_group etc.) Instead , cluster and all its variants should be used If you have some written code that is not merged yet, you will probably have a little work on rebase on top this patch, as far as I know those should be trivial patches and if you have any question, please ask. Possible affects on other products are minor and were communicated to the relevant product people. [1] https://gerrit.ovirt.org/#/c/51109/ Thanks Eli Mesika

[VDSM] health: Introduce Vdsm health monitoring
by Nir Soffer 15 Jan '16

15 Jan '16

Hi all, Continuing the leak investigation Francesco and Milan are working on, I posted this patch, adding leak health monitoring to vdsm [1]. This patch currently monitor collectible objects, and we may add other interesting stuff later if needed. To enable the monitor, you must set: [devel] health_monitor_enable = true In vdsm.conf, and restart vdsm. Here is an example logs - this was logged 60 seconds after starting vdsm, when running as spm: Thread-13::DEBUG::2016-01-14 18:53:43,239::health::84::health::(_check) Checking health Thread-13::DEBUG::2016-01-14 18:53:43,272::health::86::health::(_check) Collected 460 objects Thread-13::WARNING::2016-01-14 18:53:43,277::health::100::health::(_check) Found 5873 uncollectible objects, 10 suspects implementing __del__: ['<pthreading.Lock object at 0x7f012c115320>', '<pthreading.Lock object at 0x7f012c115440>', '<pthreading.Lock object at 0x7f012c1153b0>', '<pthreading.Lock object at 0x7f012c1154d0>', '<pthread.Cond object at 0x7f012c111350>', '<pthread.Cond object at 0x7f012c1112d0>', '<pthread.Cond object at 0x7f012c111250>', '<pthread.Cond object at 0x7f012c111850>', '<pthread.Cond object at 0x7f012c1117d0>', '<pthread.Cond object at 0x7f012c111750>'] We found 460 uncollectible objects, 10 of them are objects implementing __del__. Having such object in a reference cycle make the entire cycle uncollectible. The pthreading objects in this log grow as vdsm continue to run, even without any interaction with engine. The pthreading objects leak is caused by a cycle in storage.misc.RWLock, fixed in patch [2]. After solving the pthreading leak, we still have many uncollectible objects in the logs, listing them, it seems that the suspect is hiding inside a collection (dict, list, tuple) and does not appear in the gc.garbage list. I will address this in later patch, searching in the entire object graph instead of the top level of gc.garbage. See end of this mail for list of these objects. I printed them like this: Enable manhole debugging shell: [devel] manhole_enable = true Connect to vdsm using manhole: nc -U /run/vdsm/vdsmd.manhole Print garbage: >>> import pprint >>> import gc >>> with open('/tmp/garbage.txt', 'w') as f: pprint.pprint(gc.garbage, stream=f, indent=4) These objects looks related to libvirt - Francesco, can you take a look?

VARIANT_ID usage - with our without oVirt version?
by Fabian Deutsch 15 Jan '16

15 Jan '16

Hey, we've now merged a patch [0] to use and populate the VARIANT and VARIANT_ID fields on Node. Currently the value is something like "ovirt-node-$BRANCH", i.e. "ovirt-node-master" or "ovirt-node-3.6". I'd like to question if we should include the oVirt version in the ID, or if we should just use "ovirt-node" without the version. >From my POV the variant is not depending on a specific version, that is why I'd like to discuss it. The oVirt version can still be retieved like on any other host i.e. using rpm or maybe some file(?). - fabian -- [0] https://gerrit.ovirt.org/gitweb?p=ovirt-release.git;a=blob;f=ovirt-release-… [1] http://www.freedesktop.org/software/systemd/man/os-release.html

Summary for Vdsm sync 12.1
by Yaniv Bronheim 13 Jan '16

13 Jan '16

(edwad, nsoffer, pkliczew, alitke, fromani, ybronhei) Python3 current work and gaps - https://docs.google.com/a/redhat.com/spreadsheets/d/180F-C1jU54ajUn7TuR-Nwr… Current main gaps are the removal of deathSignal to unify cpopen api to standard Popen api, and AsyncProc which uses StringIO internal attributes which don't exist in six's stringIO . because of those two we can't import commands.py which most of the tests use. Jsonrpc client - we need to close gaps before disabling xmlrpc client - Pioter can add more words about the gaps that we currently have. Testing new storage verbs without engine - by such client ^ is a must- https://gerrit.ovirt.org/#/c/35181/6/contrib/jsonrpc basically when we finish with that we'll be able to remove vdsClient Francesco sent as update about virt items - https://www.mail-archive.com/devel@ovirt.org/msg04976.html New leak was exposed in vdsm - fromani will elaborate more once finding the exact location. Nir suggested https://gerrit.ovirt.org/#/c/51708/ to see the status of the gc and gather more internal information about the current vdsm instance - this can help to debug remotely without changing the code. -- *Yaniv Bronhaim.*

oVirt Node Upgrade Design
by Fabian Deutsch 13 Jan '16

13 Jan '16

Hey, Douglas and I have been discussing how the oVirt Node upgrade can work in future with Node Next. The most obvious change is that upgrades will be delivered directly Node. Previously they've been pushed to Node by Engine. The updates will stay to be delivered in an rpm through yum repositories, this will allow us to leverage all tooling around repos, rpm and yum. The most notable user facing benefit is, that our goal is to update Node Next by calling $ yum update Note: This will update Node in an image fashion, and will not just update the packages. Please review our design document here: http://www.ovirt.org/Node/4.0/Update - fabian
