[Engine-devel] Increasing the HTTP keep alive to 30 seconds
by Juan Hernandez 19 Dec '13

19 Dec '13

Hello, We have an RFE that has been open for quite a long time requesting an increase of the keep alive time in the HTTP communications between the GUI applications and the web server: https://bugzilla.redhat.com/833799 Implementing it should be as simple as modifying the setup application so that it includes the modified KeepAlive directives in the web server configuration, something like this: KeepAlive on KeepAliveTimeout 30 Is someone with knowledge of the setup application interested on taking this?

[Engine-devel] No-arg constructor required by default in backend "common" module's classes
by Vojtech Szocs 18 Dec '13

18 Dec '13

Hi guys, in order to avoid potential errors related to GWT RPC serialization, a recent patch [1] introduced the requirement for no-arg constructor in backend "common" module's classes. [1] http://gerrit.ovirt.org/#/c/21733/ (Even though we're planning to move away from GWT RPC to using REST API, for the time being, this should prevent RPC related errors caused by missing no-arg constructor, which are sometimes hard to trace.) For a select few classes *not* involved in RPC communication, you can add these in checkstyle-suppressions.xml file. Vojtech

[Engine-devel] Polling vs Pushing engine events
by Sven Kieske 18 Dec '13

18 Dec '13

Hi, we got the following problem: we create / start / stop hole vms /data centers / storage etc (basically: everything ovirt can handle via REST-API) But if you want to know e.g. the status of a vm (or anything) you need to constantly poll the API. This is not what we desire to do, as it does not scale very well (e.g. polling 100 vms). Is there a standardized way of pushing information from the engine? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Engine-devel] GUI widget for adding/removing entries
by Lior Vernia 17 Dec '13

17 Dec '13

Hello, Lately a patch has been merged that introduces a widget for adding/removing entries (e.g. network interfaces when creating/editing a VM): http://gerrit.ovirt.org/#/c/19530/ This kind of widgets is becoming common in oVirt, so the idea is to make adding one easy rather than copying & pasting code. AddRemoveRowWidget takes care of the plus/minus button logic, disabling an entry that hasn't been edited, and the arranging in rows. In order to use it, one is required to override a couple of abstract methods that are dependent upon the specific entry implementation. An example may be found in ProfilesInstanceTypeEditor, which handles adding/removing network interfaces in the new/edit VM dialog. Yours, Lior.

The oVirt team is pleased to announce that the 3.3.2 Release Candidate is now available in ovirt-updates-testing [1]. We planned to release it on Wed Dec 18th 2013 but it will probably be postponed to next week for allowing more testing on the RC. The release date will be decided in next oVrit sync meeting on Wed Dec 18th. Feel free to join us testing it[2] and verifying the bugzilla entries actually under verification [3]. Release notes for this update are available on the wiki [4]. A new oVirt Node build will be available soon as well.

[Engine-devel] [engine-devel] instance type as top-level entity
by Tomas Jelinek 16 Dec '13

16 Dec '13

Hey all, I have started to work on the instance types[1] again and hit an issue. Since the instance types are supposed to be top-level entities (e.g. without the connection to DC/Cluster) but they are modeled as templates it is not possible to store them to DB since the DB constraints violation on vm_static table (e.g. the vds_group_id has to be unique and point to an existing vds_group). So, I see 4 options: 1: drop the constraints on the vm_static.vds_group_id (the vds_groups_vm_static constraint) (most simple approach but would open the door to some issues which are now guard on the DB level) 2: do the same magic [well, hacks :) ] as with the "blank" template which is in the same situation (not exactly a nice solution to have the instance types wired to one specific cluster just to satisfy the constraint but return them all the time) 3: do not store this data in vm_static but create some new table called e.g. instance_type which would contain all of the fields from vm_static which are needed by it (actually the best approach AFAIK but to do it correctly it would require some more refactoring to do some hierarchy of tables and not copy the fields from table to table) 4: make the instance types not top-level (e.g. bound to specific DC/Cluster) (would bring some issues for example with the default instance types which should be present for all the DC/Clusters) Thoughts? Thank you, Tomas [1]: http://www.ovirt.org/Features/Instance_Types

[Engine-devel] developmen environment: logs
by Einav Cohen 13 Dec '13

13 Dec '13

[working on development environment] (1) I tried following instructions in [1] in order to have my engine.log log messages from the bll module in DEBUG level. After adding section [2] to the relevant file, I got an error message [3] (probably since a logger for category "org.ovirt.engine.core.bll" already exists in the file). I removed that new section, and changed the relevant string within the already-existing <logger category="org.ovirt.engine.core.bll"> from "INFO" to "DEBUG"; however, log for bll messages kept being logged only in the "INFO" level. [I restarted ovirt-engine.py after every change] Any ideas? (2) Does anyone know why queries invocation isn't being logged into the engine.log [maybe they are being logged in DEBUG level and due to (1) I cannot see them]? it seems that only action invocations are being logged. Many thanks in advance. ---- Regards, Einav [1] http://www.ovirt.org/OVirt_Engine_Development_Environment#Enable_DEBUG_log [2] --- <logger category="org.ovirt.engine.core.bll"> <level name="DEBUG"/> </logger> --- [3] [ovirt-engine-devel-env]$ ./ovirt-engine.py start Listening for transport dt_socket at address: 8787 ovirt-engine[13794] ERROR run:485 Error: process terminated with status code 1 [ovirt-engine-devel-env]$
