[Engine-devel] Proposal for new commit msg design for engine commits
by Eyal Edri 23 Aug '13

23 Aug '13

Hi, You all probably know and familiar with 'ovirt-engine' git hook for commit msg template [1]. this helps understand the general area of the patch in the project but it lacks additional info that might be valuable for scaling automatic tests in Jenkins CI. Let me explain: Infra team is working hard on expanding oVirt CI infrastructure and adding more tests in jenkins (per commit/patch). Adding important meta-data per patch can significatly improve the ability to run specific tests for each patch/commit, and not waste valuable resources on Jenkins jobs that are not relevant to the code in the patch. So the idea is to add/expand current metadata per patch, in the form of: (either) 1. expanding current header template to include more data like 'network' , 'setup', 'tools', 'virt' 2. adding a new label with relevant tags for the patch, called e.g 'METADATA: network, rest, virt' Jenkins jobs will then be able to parse that data and trigger only relevant jobs for it. this can also allow us to add more jobs per patch, an option that is very problematic today considering the amount of patches coming in to engine. Once agreed on a format, we'll be able to add a git hook to verify the validity of the commit msg. (similar to bug-url). if we're not 100% sure that the tags will cover all corner cases and we feel like we need to run the code on all jobs, we can a nightly job to run all the remaining jobs (but at least it won't run on every patch/commit).

[Engine-devel] Gluster Volume asynchronous tasks
by Sahina Bose 22 Aug '13

22 Aug '13

Hi all, We are working on a feature to add support to start and monitor gluster volume asynchronous tasks (like rebalancing a gluster volume, removing brick from volume ) from the oVirt engine. The operations can be started from the Volumes tab or the Bricks sub-tab using the Rebalance, Remove options. These are long running operations which can be monitored using a task id returned from Gluster. We are planning to add the monitoring in the existing Task sub tab The feature description and User flows are at http://www.ovirt.org/Features/Gluster_Volume_Asynchronous_Tasks_Management The detailed design (including REST API design) is at http://www.ovirt.org/Features/Detailed_Gluster_Volume_Asynchronous_Tasks_Ma…. I would really appreciate if you could review and provide your valuable feedback. thanks sahina

[Engine-devel] Feedback/ input needed on Host power management
by Malini Rao 21 Aug '13

21 Aug '13

Hello all, In taking a look at the current implementation of Hosts> Power management, we have come up with a couple of approaches on improving this from a UX perspective -http://www.ovirt.org/Talk:Community#UXD_Proposals_for_Host_Power_management. We want your thoughts and input on what approach makes more sense from a user's perspective before fine tuning the UI. Thanks Malini User Experience designer

[Engine-devel] Issues with IBM POWER support in oVirt engine

--_000_B2CAFC4D5E2D574A883EF61ACD5ADE330180A712SERV070corpeldo_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi everyone, I wrote some code to run a VM on a IBM POWER host, but I stumbled in some i= ssues that will need a little bit of refactoring in the current code and I = would like some feedback. The first issue is that KVM on POWER requires a special SCSI interface (cal= led SPAPR), which is not available in x86-64. Currently I'm solving this pr= oblem by using (in the VmInfoBuilder class): if (vm.getArchitecture().equals(ArchitectureType.ppc64)) { Map<String, Object> struct =3D new HashMap<String, Object>(); struct.put(VdsProperties.Type, VmDeviceType.CONTROLLER.getName(= )); struct.put(VdsProperties.Device, VdsProperties.Scsi); // Create a controller in the index 1, the VirtIO_SCSI interface= is in index 0 struct.put(VdsProperties.Index, "1"); Map<String, String> spaprAddress =3D new HashMap<String, String= >(); spaprAddress.put("type", "spapr-vio"); struct.put(VdsProperties.Address, spaprAddress); devices.add(struct); } But this is a poor solution, because this class would be polluted by archit= ectural differences. Another thing to notice is that since in IBM POWER the= re are two SCSI controllers, all the SCSI devices must have their SCSI addr= ess explicitly defined (it was not needed before, since there was just one = controller before). It was proposed that a "strategy" class could solve the= problem, but I would like to have some feedback on which package it should= be, since it will also be used in the bll package to validate other stuff. The second issue is that the CD-ROM interface is SCSI on POWER guests (and = must be attached to the SPAPR interface) and IDE on the x86_64, this inform= ation could be retrieved from the osinfo (by creating a property there) or = It could be hard-coded in the strategy class. Which would be the best way to handle this difference? The third and final issue is that when the VNC protocol is used in a VM, by= default a Cirrus Logic VGA device is created. This device is not supported= on POWER guests, but the standard VGA device is. I made a workaround, but = the issue is where to put this association between the device type and the = display protocol. Should it also be a property in the osinfo? Or it should be handled in the = strategy class? --_000_B2CAFC4D5E2D574A883EF61ACD5ADE330180A712SERV070corpeldo_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Dus-ascii"= > <meta name=3D"Generator" content=3D"Microsoft Word 14 (filtered medium)"> <style></style> </head> <body lang=3D"PT-BR" link=3D"blue" vlink=3D"purple"> <div class=3D"WordSection1"> Hi everyone,<o:p></o:p><= /p> <o:p> </o:p> I wrote some code to run a VM o= n a IBM POWER host, but I stumbled in some issues that will need a little b= it of refactoring in the current code and I would like some feedback.<o:p><= /o:p> <o:p> </o:p> The first issue is that KVM on = POWER requires a special SCSI interface (called SPAPR), which is not availa= ble in x86-64.

[Engine-devel] oVirt UI technology stack upgrade complete
by Vojtech Szocs 20 Aug '13

20 Aug '13

Hello everyone, last week, we merged a patch that upgrades oVirt UI technology stack to use the latest version of Google Web Toolkit SDK and related modules [1]. This patch includes all "essential" upgrade changes as described in [2]. After merging the above mentioned patch, we faced some issues related to GWT RPC serialization, involving classes shared between frontend and backend. Please read on to learn more about these issues and ways to fix them. -- (A) NullPointerException at server-side (GWT RPC servlet) when serializing backend business entity into RPC response payload Symptoms * exception in server.log -> Exception while dispatching incoming RPC call: java.lang.NullPointerException * error dialog in web UI with status code 500 (internal server error) Root cause * fields such as "private X field = Y;" of the given entity are not included in GWT RPC serialization policy * this happens when entity constructor isn't referenced in UI code -> GWT compiler marks the constructor and instance initializer as dead code * since instance initializer takes care of adding such fields to given type (entity) in generated JavaScript, such fields won't be added at all Workaround * for each field such as "private X field = Y;" 1, change field declaration to "private X field;" 2, add "field = Y;" statement to constructor Consequence * even though constructor and instance initializer are marked as dead code, fields such as "private X field;" are still added to given type (entity) in generated JavaScript * this is due to how generated JavaScript works, i.e. fields without initialization statement such as "private X field;" are always added, whereas fields with initialization statement such as "private X field = Y;" are added via instance initializer (which might be removed if it's marked as dead code) References * patch [http://gerrit.ovirt.org/#/c/17352/] for RepoImage entity -- (B) Instance field(s) with null values at server-side after deserializing RPC request payload Symptoms * object passed from client contains field(s) with null values, despite client initializing fields before making RPC call Root cause * client uses RPC method signature that works with type A, i.e. VdcActionParametersBase * type A meets GWT RPC serialization rules, as defined in [3] section "Serializable User-defined Classes" * client uses type B (extends A) when calling given RPC method at runtime, i.e. MyCustomParameters * type B does NOT meet GWT RPC serialization rules, i.e. missing no-arg constructor * back at server-side, GWT RPC servlet fails to deserialize type B properly Workaround * ensure all types participating in GWT RPC communication meet GWT RPC serialization rules 1, assignable to IsSerializable or Serializable interface 2, all non-final & non-transient instance fields meet GWT RPC serialization rules 3, contains no-arg constructor (in order to create instance during deserialization) References * patch [http://gerrit.ovirt.org/#/c/17368/] for Gluster Parameter classes -- Regards, Vojtech [1] http://gerrit.ovirt.org/#/c/16739/ [2] http://www.ovirt.org/Features/GWT_Platform_Upgrade [3] http://www.gwtproject.org/doc/latest/DevGuideServerCommunication.html#DevGu…

[Engine-devel] Dynamic resource loading in GWT
by Roy Golan 20 Aug '13

20 Aug '13

Painful issue here - we all know the regular drill of maintaining messages in many places, I18N files and so on. Also there's a patch to make all available timezone an java enum and by that share it for free with the UI. its a way better than a backend Query. But this is all hard-coded, not flexible, hard to maintain, we all know. Why won't we make GWT load a javascript dictionary/dictionaries from a servlet or our host page html[1] using GWT Dictionary[3]? that way the configuration is shared with the engine, it relies on the disk, customers and GSS can change it on-site and so on. | index.html | -> | file servlet | -> |read /etc/ovirt-engine/conf/...| ^ | | GWT loads Dictionary | candidates for dynamic resources * I18N resources AppErrors... * config ( just the UI subset ) * osinfo ?
