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

Fwd: Re: [ovirt-devel] [QE] oVirt 3.4.1 RC status

by Sven Kieske

I just wanted to let the users list know this, because I think the interest on the users list will be much higher to get debian into ovirt ;-) https://bugzilla.redhat.com/show_bug.cgi?id=1073453 -------- Original-Nachricht -------- Betreff: Re: [ovirt-devel] [QE] oVirt 3.4.1 RC status Datum: Thu, 17 Apr 2014 10:49:14 +0000 Von: Sven Kieske <S.Kieske(a)mittwald.de> An: devel(a)ovirt.org <devel(a)ovirt.org> Well I added some questions to the tracker bug. It would be huge if "Debian 7" could be selected as a vm OS. I don't see anything preventing this tbh, but it's just not implemented yet (shouldn't be much work?)

oVirt - RHEV release

by Maurice James

------=_Part_353_1377390067.1397732327075 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit I'm curious about which version of oVirt will power the next release of RHEV. Here is why I ask. I have come across a few major problems since upgrading to 3.4.x (External Authentication BZ1081204, Quota assignment BZ1081014, Live migration "qemu bug" ) to name a few. I imagine that all of the features need to be polished before inclusion into RHEV. I'm trying to get my company to adopt RHEV instead of V-Sphere but that is becoming a little tricky. Minus the cool new features of 3.4.x 3.3.4 was pretty stable IMO. ------=_Part_353_1377390067.1397732327075 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: quoted-printable <html><body><div style=3D"font-family: times new roman, new york, times, se= rif; font-size: 12pt; color: #000000"><div><span style=3D"color: #333333; f= ont-family: monospace; font-size: 13px; background-color: #fafafa;" data-mc= e-style=3D"color: #333333; font-family: monospace; font-size: 13px; backgro= und-color: #fafafa;">  I'm curious about which version of oVirt will p= ower the next release of RHEV.

[Users] Instructions to add a remote controlled power strip not in the native list?

by David Smith

We use Raritan / Dominion PX remote power blocks, is there a way to easily add support for these? On a feature request side, seems like adding support for generic wouldn't be too hard; just ask for what the login/password prompts look like, what the main prompt is, and the command sequence to turn on and off a port as well as logout.
