Hi all, and happy holidays. I would like to give a small reminder about the contents of 0000_config.sql - We are trying to keep an alphabetical order when it comes to the option names (the keys). Thanks, Yair

[ACTION REQUESTED] please review new oVirt look-and-feel patch
by Greg Sheremeta 23 Apr '14

23 Apr '14

Hi, A while back, I sent out an email for the new oVirt look-and-feel feature [1]. The new look and feel patch is ready for both code and UI review. At this point we're not looking for design review, although you are welcome to suggest design improvements. I'm mostly looking for help regression testing the entire UI. Especially if you're an oVirt *UI* developer, please download the patch and try it [2]. The patch introduces some new CSS globally, and I had to adjust many screens and dialogs. It's quite possible that there are dialogs that I don't know about, so if you maintain any especially-hidden dialogs, please try the patch and verify your dialogs look good. And you can also just try out the patch to see the amazing new look and feel! Thanks for your feedback.

Is there a way using RHEVM ReST API 3.2, to fetch the hostname(DNS name) of a virtual machine? There is IP address available under <vm> <guest_info> <ips> <ip address=""/> </ips> </guest_info> </vm> but, no way to fetch the hostname. Please guide.

[vdsm] NUMA support broken on UMA machines
by Adam Litke 23 Apr '14

23 Apr '14

Hi, Commit 9d3311320f6fcf190c99068b3f566e2bf9a49d99 "caps: Collect numa information" bruce <xiao-lei.shi(a)hp.com> Introduced reporting of numa-related information in the getVdsCaps verb. Unfortunately it also introduced a bug in machines without NUMA support. On my mini-dell, the getVdsCaps verb is failing with the following exception: Thread-13::ERROR::2014-04-21 11:57:09,908::BindingXMLRPC::1068::vds::(wrapper) l ibvirt error Traceback (most recent call last): File "/usr/share/vdsm/BindingXMLRPC.py", line 1061, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/BindingXMLRPC.py", line 388, in getCapabilities ret = api.getCapabilities() File "/usr/share/vdsm/API.py", line 1193, in getCapabilities c = caps.get() File "/usr/share/vdsm/caps.py", line 458, in get caps['numaNodes'] = _getNumaTopology() File "/usr/lib64/python2.7/site-packages/vdsm/utils.py", line 958, in __call__ value = self.func(*args) File "/usr/share/vdsm/caps.py", line 189, in _getNumaTopology memInfo = _getMemoryStatsByNumaCell(int(cellIndex)) File "/usr/share/vdsm/caps.py", line 203, in _getMemoryStatsByNumaCell return libvirtconnection.get().getMemoryStats(cell, 0) File "/usr/lib64/python2.7/site-packages/vdsm/libvirtconnection.py", line 92, in wrapper ret = f(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3405, in getMemoryStats if ret is None: raise libvirtError ('virNodeGetMemoryStats() failed', conn=self) libvirtError: internal error: NUMA isn't available on this host I guess we need to catch this error and respond appropriately. -- Adam Litke

Re: [ovirt-devel] [Engine-devel] ui plugin problems, cannot read from a file.
by Vojtech Szocs 18 Apr '14

18 Apr '14

Hi guys, > hey, am trying to display the contents of a text file in a java > applet as a ui plugin in ovirt. > The same applet performs successfully when run as a standalone, but > fails to deliver when the it is run through ovirt. UI plugins are written in JavaScript and HTML. UI plugin is technically standalone web application sandboxed within invisible <iframe> element under WebAdmin's DOM. UI plugin uses API to extend existing WebAdmin functionality through custom UI components (main tab, dialog, etc). Java applet technology cannot be used to implement UI plugin because plugin vs. WebAdmin integration happens on JavaScript/HTML level. I suggest to check out samples-uiplugins git repo for examples: http://www.ovirt.org/Features/UIPlugins#Sample_UI_plugins If you really want to write UI plugin in Java language, you can use GWT (as suggested by Greg) which yields JavaScript/HTML output. In general, any technology/language that ultimately yields JavaScript code can be used to implement UI plugin. > isn't one of the points of a uiplugin it doesn't have to be GWT based > (as its not going to be part of the codebase)? In fact, UI plugins can be written in GWT, if desired. However, as you mentioned, plugins are decoupled from WebAdmin code base through the plugin infra/subsystem.

UI plugins: AngularJS Demo Plugin
by Vojtech Szocs 17 Apr '14

17 Apr '14

Hi guys, for those of you interested in AngularJS, there's now a sample oVirt UI plugin available from samples-uiplugins repo: http://www.ovirt.org/Features/UIPlugins#AngularJS_Demo_Plugin (It's very similar to one presented in our recent "Writing UI plugin with AngularJS" presentation.) When writing UI plugins beyond simple "hello world", it's important to keep the code well-structured and maintainable; utilizing proven patterns like Model-View-Controller, Dependency Injection, etc. seems to be a good way to go. Of course, some JavaScript ninjas might do things in a different way. :) Regards, Vojtech

Question about plan/work for javascript SDK
by Yair Zaslavsky 15 Apr '14

15 Apr '14

Hi, Unfortunately I could not attend the tech talk Vojtech presented this week (I did attend the 2nd one about UI-Plugins and Anjular JS). I was wondering if 3rd party developers will be able to use the ovirt.js library/framework for developing JS-based tools around oVirt (let's say - using the MEAN stack). Not sure how much we gave thought to this, so I'm asking here Thanks for any insights on this, Yair
