Hi, I tried building an ovirt engine RPM for the first time on my Fedora17 machine using the wiki instructions. I get the following error - # make rpm sed -e 's/@PACKAGE_VERSION@/3.3.0/g' \ -e 's/@PACKAGE_RELEASE@/0.1.20130208174746/g' packaging/fedora/spec/ ovirt-engine.spec.in > ovirt-engine.spec git ls-files | tar --files-from /proc/self/fd/0 -czf ovirt-engine-3.3.0.tar.gz o virt-engine.spec rm -f ovirt-engine.spec You can use rpmbuild -tb ovirt-engine-3.3.0.tar.gz to produce rpms rm -rf /home/guest/ovirt-engine/tmp.rpmbuild mkdir -p /home/guest/ovirt-engine/tmp.rpmbuild/{SPECS,RPMS,SRPMS,SOURCES,BUILD,B UILDROOT} mkdir -p output rpmbuild -ts --define="_topdir /home/guest/ovirt-engine/tmp.rpmbuild" ovirt-engi ne-3.3.0.tar.gz Wrote: /home/guest/ovirt-engine/tmp.rpmbuild/SRPMS/ovirt-engine-3.3.0-0.1.201302 08174746.fc17.src.rpm mv /home/guest/ovirt-engine/tmp.rpmbuild/SRPMS/*.rpm output rm -rf /home/guest/ovirt-engine/tmp.rpmbuild srpm is ready at output rm -rf /home/guest/ovirt-engine/tmp.rpmbuild mkdir -p /home/guest/ovirt-engine/tmp.rpmbuild/{SPECS,RPMS,SRPMS,SOURCES,BUILD,B UILDROOT} mkdir -p output rpmbuild --define="_topdir /home/guest/ovirt-engine/tmp.rpmbuild" --rebuild out put/ovirt-engine-3.3.0*.src.rpm Installing output/ovirt-engine-3.3.0-0.1.20130208172931.fc17.src.rpm error: Failed build dependencies: ovirt-host-deploy-java is needed by ovirt-engine-3.3.0-0.1.2013020817293 1.fc17.noarch make: *** [rpm] Error 1 -Sharad

[Engine-devel] Import/snapshots duplicate MAC support
by Mike Kolesnik 10 Feb '13

------=_Part_14223209_123477223.1360131191449 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, The current situation dictates that if the configuration value AllowDuplicateMacAddresses is set to false (this is the default setting), then we block import or switching snapshots where a MAC address in one or more of the snapshot/ovf's virtual NICs is already used. Given that we don't currently give the admin any option to select otherwise, I'm not sure that's a very robust behaviour.. First of all the MAC address should be unique per network and not in the whole system (like it is currently). Furthermore, as long as in the same network there are no two virtual NIC s running with the same address, it is not such a bad situation. Therefore, I would like to propose a couple of solutions (from backend perspective): 1. Keep blocking. 2. Keep blocking but fix the mac pools to be per network basis. 3. Don't block, and allow duplicate MACs in these scenarios, but block on activating a NIC with duplicate MAC address. Warn the user that the NIC is with duplicate MAC, and perhaps even unplug or unwire it so that it would be obvious that it's using someone else's MAC. 4. Don't block, and give the problematic NIC a new MAC from the pool. Solution 1 is obviously not the greatest (hence this email). In my opinion, 4 is sort of a cat in a bag, since I'm not sure changing the HWADDR for the guest OS is really a good idea. Solution 2 would be nice going forward, but it just reduces the chances of an admin to come across this situation and doesn't solve it entirely. Hence, I would favour solution 3 which seems to solve the problem and allow the admin to choose what to do. Please voice your opinion, or propose an alternate solution.

[Engine-devel] NPE during addStorageServer command
by Deepak C Shetty 08 Feb '13

08 Feb '13

Hi All, I am trying to compile ovirt engine after applying sharad's glusterfs domain support patches @ http://gerrit.ovirt.org/#/q/project:ovirt-engine+branch:master+topic:gluste… After compiling, deploying the engine ( by following the steps in wiki.ovirt.org/Building_Ovirt_Engine ) I connect to the weadmin GUI, add a VDSM host ( this is my own vdsm host with VDSM glsuter domain support ) and the host is "Up" state. Then I select New SD->None in DC -> select my vdsm host->provide the args (remote path = volfileserver:volume, vfstype=glusterfs, mount => left blank) and click on OK I see NPE in the engine side during addStorageServer cmd ( IIUC ) and then engine tries to send disconnectStorageServer, which reaches my VDSM host and it throws a excp, since the domain is not mounted at all. I have captured the logs on the engien and vdsm side and attached here. I am looking for some help on why the NPE is being seen on the engien side during adding a new SD ? thanx, deepak

[Engine-devel] Proposing Kiril nesenko as power user for "ovirt engine tools"
by Eyal Edri 07 Feb '13

07 Feb '13

Hi, I would like to propose kiril nesenko as 'jenkins power user' for ovirt engine tools. These tools indlude iso uploader, log collector, image uploader and others. Kiril is very involved in building and running Jenkins jobs on the rhevm product, and maintains & package the ovirt tools currently. As part of being power user on jenkins.ovirt.org, he will create new jobs to build and release tools for the various OS supported. I vote +1 as i personally know kiril and he's experience. Thansk, Eyal.

[Engine-devel] engine-config behaviour on -g by alternateKey
by Martin Betak 07 Feb '13

07 Feb '13

Hi All, I've been working on the ability to set keyboard layout for VNC server as per each individual VM. Currently the only option is to use engine-config to set the value globally, e.g. engine-config -s VncKeyboardLayout=en-us. After adding this option to database and respective entities there were raised valid concerns about why is this option called VncKeyboardLayout and not just KeyboardLayout as it applies to SPICE equally (note that also VDSM calls this config value as 'keyboardLayout'). So to achieve consistency I also renamed it in engine-config.properties and set KeyboardLayout.alternateKey=VncKeyboardLayout. This indeed works for setting (engine-config -s VncKeyboardLayout=en-us sets KeyboardLayout and engine-config -g KeyboardLayout works but it is unable to read the value by the alternateKey) engine-config -g VncKeyboardLayout fails with "no such entry with default version" in the method EngineConfigLogic.printAllValuesForKey as it is passing the user given key name directly to database which returns zero results. Setter methods such as EngineConfigLogic.persistValue use the entity ConfigKey constructed from the user given key-name which correctly constructs appropriate ConfigKey even when given alternateKey name. So I wanted to ask whether this is the desired behaviour (set by alternateKey name but get only by the primary) or is this a bug? I have also simple patch that fixes this and enables also getting the config value by alternateKey. Thank you

[Engine-devel] Instance Types Feature
by Tomas Jelinek 07 Feb '13

07 Feb '13

Hi All, this is the proposed new feature called instance types: http://www.ovirt.org/Features/Instance_Types Long story short - it should basically split the VM template into: - "hardware profile" called instance types - "software profile" called image This should enable to do something like: Create a new "small" VM and attach a disk with "RHEL + Postgres" installed. Any comments are more than welcome! Tomas

[Engine-devel] UI Plugin API: Introducing optional arguments object
by Vojtech Szocs 05 Feb '13

05 Feb '13

Hi guys, as we're planning to improve some plugin API functions [1,2] I'd like to introduce the concept of optional arguments ('options') object, very similar to jQuery 'settings' object [3]. Each API function will declare only mandatory (required) arguments as part of its signature, with any optional arguments embedded within the 'options' object. The 'options' object itself will be optional (can be omitted) and will always be the last argument of each API function. For example: // Without 'options' object, all optional arguments fall back to their default values showDialog('My Dialog', 'my-dialog', 'http://www.example.com/', '800px', '600px') // With empty 'options' object, all optional arguments fall back to their default values showDialog('My Dialog', 'my-dialog', 'http://www.example.com/', '800px', '600px', {}) // With non-empty 'options' object, overriding default 'resizeEnabled' optional argument value showDialog('My Dialog', 'my-dialog', 'http://www.example.com/', '800px', '600px', { resizeEnabled: true }) Support for this concept should be part of [1].

[Engine-devel] UI Plugins: HTML5 Window.postMessage communication scheme proposal
by Vojtech Szocs 05 Feb '13

05 Feb '13

Hi guys, showDialog API improvement patch [http://gerrit.ovirt.org/#/c/11717/] is planned to include new feature that allows custom content contributed by UI plugins to invoke arbitrary plugin API function. For example, imagine you have a custom modal dialog created via showDialog API: showDialog('Dialog Title', 'dialog-token', 'http://www.example.com/', '800px', '600px') Alternatively, you could also have a custom main tab created via addMainTab API: addMainTab('Tab Label', 'tab-token', 'http://www.example.com/') WebAdmin uses HTML iframe element to render custom content at http://www.example.com/ from within the dialog/tab UI. Now imagine the custom content shows a button that should invoke some plugin API function. For example, imagine a custom "Close" button rendered within the modal dialog content. For this purpose, we're planning to use following HTML5 Window.postMessage communication scheme: * custom content iframe (attached to top-level DOM) does postMessage <pluginName>:<apiExpression>, e.g. foo-plugin:closeDialog('my-dialog') * WebAdmin receives the message, obtains pluginApi for <pluginName> and invokes <apiExpression> on it, e.g. fooPluginApi.closeDialog('my-dialog') The above scheme allows *any* custom content iframe (showDialog, addMainTab, etc.) to invoke arbitrary plugin API function (expression). This means that custom content contributed by UI plugins can interact directly with plugin API on its own. In other words, this gives plugin authors the possibility to call plugin API without having to notify the plugin (JavaScript) in one way or another. Let me know what you think. Vojtech
