Re: ovirt-engine-sdk with C (Jarod. w) Yes, you understanded my idea, I want to use c to invoke ovirt engine RestAPI directly, I'll try it(libcurl), but is there any exist example in ovirt-engine project. I just want to connect to ovirt-engine and get vms info, console vm and do some action(start, stop.). thinks. -----ÓÊŒþÔŒþ----- ·¢ŒþÈË: engine-devel-bounces(a)ovirt.org [mailto:engine-devel-bounces@ovirt.org] Žú±í engine-devel-request(a)ovirt.org ·¢ËÍÊ±Œä: 2013Äê5ÔÂ14ÈÕ 14:19 ÊÕŒþÈË: engine-devel(a)ovirt.org Ö÷Ìâ: Engine-devel Digest, Vol 20, Issue 39 Send Engine-devel mailing list submissions to engine-devel(a)ovirt.org To subscribe or unsubscribe via the World Wide Web, visit http://lists.ovirt.org/mailman/listinfo/engine-devel or, via email, send a message with subject or body 'help' to engine-devel-request(a)ovirt.org You can reach the person managing the list at engine-devel-owner(a)ovirt.org When replying, please edit your Subject line so it is more specific than "Re: Contents of Engine-devel digest..."

[Engine-devel] spice-xpi(firefox) plugin for Windows
by Christophe Fergeau 13 May '13

13 May '13

--tsOsTdHNUZQcU9Ye Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi everyone, Lately I've been hacking on getting the spice-xpi plugin to work on Windows. This is the Firefox plugin that is used on Linux to implement the portal SPICE console. This work has now been merged upstream ( http://cgit.freedesktop.org/spice/spice-xpi/ ), and I've pushed a scratch build using mingw available from http://koji.fedoraproject.org/koji/taskinfo?taskID=5265107 (this will go away in several days). Copying this dll + its dependencies to the C:\Program Files\Mozilla Firefox\plugins directory are enough to get a spice-xpi plugin to show up in about:plugins, and to then be able to start a SPICE client from the spice-xpi test page ( http://teuf.fedorapeople.org/plugins/test.html ). The dependencies I had to copy are: gspawn-win32-helper-console.exe gspawn-win32-helper.exe iconv.dll libffi-6.dll libgcc_s_sjlj-1.dll libgio-2.0-0.dll libglib-2.0-0.dll libgmodule-2.0-0.dll libgobject-2.0-0.dll libgthread-2.0-0.dll libintl-8.dll libstdc++-6.dll pthreadGC2.dll zlib1.dll (I picked them from the various mingw-* fedora packages). The reason for this email is that to be usable from oVirt, some portal changes are needed as it currently only tries to use the spice-xpi plugin on Linux platforms. Another fuzzy bit is how to get this plugin to the users' machines... And that's about all I had to say in that email ;) Let me know if that's useful to oVirt, how you want to integrate this, ...

[Engine-devel] DB performance optimization
by Liran Zelkha 13 May '13

13 May '13

Hi all, There is a WIP for caching and DB performance optimization. Please look at - http://gerrit.ovirt.org/#/c/14188/4 To summarize, it includes automatic caching for some business entities (*_static for instance), break up of VDS to VDS_static, VDS_dynamic and VDS_statistics, and support for batch updates. Please share if/where you think batch updates can be used (for a usage scenario, please check InterfaceDaoDbFacadeImpl.massUpdateStatisticsForVds()). Future tasks will include update sensitivity, better Collection caching and trying to minimize getConnection() calls. Would love your comments and ideas. Thanks.

[Engine-devel] [ANN] Technology preview of new ovirt-engine setup
by Alon Bar-Lev 12 May '13

12 May '13

Hello, We[1] are working on a re-implementation of ovirt-engine setup to a more advanced and customizable implementation. A significant feature is the ability to use the installer on different distributions, first was Gentoo[2], I am working on Ubuntu. Another[3] major features is the ability to use the same setup procedure for production and development. Among of other changes is the option to install product into existing database without having the DBA user, avoid redirection of root URI into application, ability to customize almost anything, and the option of localization. Although this is technology preview and likely to break, we merged this so people may experience the new setup at early stage and provide feedback so we may solve as many issues as we can before product release. So come on, you brave people... let's see you break our setup! This should be available at tomorrow's nightly packages. STATUS Side-by-side installation New installer and legacy installers are available side-by-side. Legacy installer: engine-setup, engine-upgrade, engine-cleanup. New installer: engine-seutp-2, engine-cleanup-2. This means that once ovirt-engine is installed, there is an option to use the legacy setup or the new setup. Compatibility Onces setup is done by either, it cannot be updated by the other. We will work toward having a solution of upgrade legacy to the new, but not the other way around. Coverage setup should be feature complete. cleanup currently only clean files that were created by the setup, not these which were modified. upgrade is implemented using re-execution of setup, currently only database upgrade is performed, no package upgrade. Thank you, Sandro Bonazzola, Alex Lourie, Alon Bar-Lev [1] Sandro Bonazzola, Alex Lourie, Alon Bar-Lev [2] https://wiki.gentoo.org/wiki/OVirt [3] http://lists.ovirt.org/pipermail/engine-devel/2013-May/004532.html

[Engine-devel] VDSM Fake
by Libor Spevak 12 May '13

12 May '13

Hi, let me introduce an experimental project called VDSM Fake. This is a small Java web application simulating selected VDSM features, but only from the Engine point of view. The aim was to get oVirt-Engine top performance characteristics in core features simulating hundreds of fake hosts and VMs, and in ecologic way. More info: http://www.ovirt.org/VDSM_Fake Sources: git clone git://github.com/lspevak/ovirt-vdsmfake.git git clone git://github.com/lspevak/ovirt-restapiconf.git Regards, Libor

[Engine-devel] Migrating engine-setup to otopi
by Alex Lourie 10 May '13

10 May '13

Hi All Recent development of the otopi [1] framework allows us to migrate the engine-setup, upgrade and cleanup (and potentially other) utilities to implementation as an otopi plugin. Potential benefits of such a move are: 1. Be able to port engine to other distributions. 2. Be able to install engine in a development mode. 3. Be able to customize installation easily. 4. Share installation of components (reports, dwh). 5. Modular implementation, reduce maintenance costs. 6. Code reuse of installer code for multiple purposes (host-deploy, enigne-setup). Currently we are in the process of creating a 'setup' plugin for the otopi, and the progress can be monitored at [2]. The current roadmap for the feature is as follows: 1. Recreate the configuration utilities as plugins in otopi. 2. Support side-by side installation using both the old and the new utilities. 3. Switch to the new utility when the confidence that it is on-par with an old one is high. Our goal is to have the new utilities ready for 3.3 release (at least for the step 2 in the roadmap). We'd like to hear as much feedback as possible, so we could address it as soon as possible. Thanks!

[Engine-devel] Device custom properties
by Martin Perina 09 May '13

09 May '13

Hi, I'm currently trying to implement device custom properties infrastructure in ovirt-engine. During discussion with Yair, we found out, that it's not clear, for what type of devices custom properties should be available? In engine we have the VmDeviceType enum which contains following values: FLOPPY("floppy", "14"), DISK("disk", "17"), CDROM("cdrom", "15"), INTERFACE("interface", "10"), BRIDGE("bridge", "3"), VIDEO("video", "20"), USB("usb", "23"), CONTROLLER("controller", "23"), REDIR("redir", "23"), SPICEVMC("spicevmc", "23"), QXL("qxl"), CIRRUS("cirrus"), SOUND("sound"), ICH6("ich6"), AC97("ac97"), MEMBALLOON("memballoon"), SMARTCARD("smartcard"), BALLOON("balloon"), OTHER("other", "0"), UNKNOWN("unknown", "-1"); But VmDevice class has two String attributes device and type. So for example a disk is a device which has device set to disk and type set to disk (according to VmDeviceCommonUtils.isDisk method). So my question is, if I have a custom properties for disk, will they be available for all disk devices (disk, cdrom, floppy, ...) or only for real disk? So should we support custom properties for all VmDeviceType enum value separately? Thanks for suggestions Martin
