Are the two files referred (the .dmp and the .xml that I collected) useful to analyze anything? Do the contain sensitive data? The win7 VM has spice-guest-toos-0.3 installed and defined with spice console. It is the first win7 VM on final 3.2, while on another cluster with 3.2 beta I have another similar one (same iso) that stays up for several days without problem, so I presume something possible with particular hw of this node: HP BL685c G1 with 32Gb of ram AMD Opteron G2 (quad sockets dualcore) OS Version: Fedora - 18 - 1 kernel 3.7.8 - 202.fc18.x86_64 qemu-kvm 1.2.2 - 6.fc18 vdsm-4.10.3-8.fc18 libvirt-0.10.2.3-1.fc18 spice 0.12.2 - 3.fc18 active VMs : 4 Thanks, Gianluca

[Users] Ovirt & iSCSI
by Alex Leonhardt 22 Feb '13

22 Feb '13

Hi All, I was wondering if there is a document that describes in detail how ovirt is working with iscsi and how it creates the disks, etc. etc. on the SAN / iSCSI storage ? I checked the online documentation however cant see it going into much detail. I'd also be prepared to write something up for the documenation section, but I need to get it to work and understand first ;) FWIW, this is a part 2 of a project I'm working on, now moving away from NFS and onto iSCSI (a cheap san solution). Your help would be greatly appreciated. Thanks! Alex -- | RHCE | Senior Systems Engineer | www.vcore.co | www.vsearchcloud.com |

[Users] VNC web console
by Jaco 22 Feb '13

22 Feb '13

I've seen this in the list archives, but not sure how much traction it's gained in the intervening period (or ). I've fiddled with, and had some pretty decent experiences with Guacamole: http://guac-dev.org/ An HTML(5?)-based VNC client for a browser - no client-side components needed :) Could fit in nicely with the project. Just putting it out there - J

You can achieve this by using the 'optimize' button in the webui while looking at the Volume. Joop -- irc: jvandewege

[Users] Backup and restore procedure?
by Jonathan Daugherty 22 Feb '13

22 Feb '13

Greetings, I'm working on deploying oVirt for the first time and I need to know what needs to be backed up in order to be prepared for a system recovery. Is this documented? For the engine, so far I imagine I'd want to back up /etc and dump my postgres database; the restore procedure for both of those is trivial. For the nodes, other than /etc, I don't know what needs to be backed up or what the restore procedure is. (And backing up /etc just for this seems a bit ham-fisted.) What am I missing? Thanks! -- Jonathan Daugherty Software Engineer Galois, Inc.

[Users] vlan interface failed : Bridged network Internet is attached to multiple interfaces: <UNKNOWN> on Host node1.
by Kevin Maziere Aubry 22 Feb '13

22 Feb '13

Hi there Few weeks ago I report on the 3.2beta a problem to set a new Vlan tagged interface. I've sent logs to Antoni. Now on the stable release, fresh install, I try to add a vlan tagged interface, and I have exactly the same error. I don't understand how such a problem in a stable release is possible ? Does anyone success to had a vlan ? I can't use ovirtmgmt network to go to Internet, so that i can't use 3.2 release. I can send log again if needed, just ask :) Kevin -- Kevin Mazière Responsable Infrastructure Alter Way – Hosting 1 rue Royal - 227 Bureaux de la Colline 92213 Saint-Cloud Cedex Tél : +33 (0)1 41 16 38 41 Mob : +33 (0)7 62 55 57 05 http://www.alterway.fr

[Users] workflow for minor updates in al-in-one config
by Gianluca Cecchi 22 Feb '13

22 Feb '13

Suppose that for your Fedora 18 oVirt 3.2 all-in-one config, where you have both the engine (ovirt-engine service) and the node (vdsmd service) there are a bunch of updates available such as: vdsm kernel ... is it correct to go through the workflow below? 1) stop running VMs 2) upgrade engine 2a) no related updates # engine-upgrade Checking for updates... (This may take several minutes)...[ DONE ] No updates available 2b) some related updates (eg. Supposing x.y below is the same as the one currrently installed Checking for updates... (This may take several minutes)...[ DONE ] 11 Updates available: * ovirt-engine-x.y.x-4.fc18.noarch * ovirt-engine-backend-x.y.z-4.fc18.noarch .. Error: New ovirt-engine-setup rpm available via yum. Please execute `yum update ovirt-engine-setup`, then re-execute 'engine-upgrade'. ) # yum update ovirt-engine-setup # engine-upgrade 3) stop engine # systemctl stop ovirt-engine.service 4) stop vdsmd # systemctl stop vdsmd.service 5) update remaining system packages if something already done in step 2 # yum update 6) reboot and check all is ok Gianluca

Wow. That's an incredibly tight focus! I've always recommended targeting "all human beings" (including blind, color-blind, and physically handicapped people) mostly because I think those damn Martians and Jovians are a bunch of whiners. They should stop complaining about being excluded and just learn to live at one Earth gravity like normal right-thinking people. Working towards a maximally useful product wastes resources, and the aliens will never buy Earth goods anyway. --Charlie On Wed, Feb 20, 2013 at 11:00 AM, Noam Slomianko <nslomian(a)redhat.com> wrote: > After an interesting presentation by Dave Neary today we started thinking about the persona[*] of the ovirt project users > We focused on the users of the new coming feature of UI plugins. > And this was our vision of an active user: > > Name: Dan > Age: 25 > Job position: an integrator at a medium sized service company > Technical level: computer savvy person with interest in gadgets and innovations. > Has about two years of java coding experience, but coding may not be his main focus at work. > Reason for using the UI Plugins feature: After getting requests from his costumers for simple log monitoring feature, the integration team leader have decided that implementing this as a Plugin for ovirt > would offer a more centralised solution and has assigned dan to start getting familiar with it and give him a time estimation for completion. > > > By creating a more accurate persona(s) of the user base we could more easily understand the needs of the users and steer the project in more productive and helpful ways for the people that really need it. > It would be very interesting to see what others think this "person" is like and what does he need. > so who do you feel is the likely user? > > In hopes of making ovirt better and more relevant to its users, > Noam. :) > > > [*] For those who don't know what a persona is: It's a fictional "person" that represents the users/costumers/"people of interest" of a product. by giving this "person" a name, age, education level and other traits its easier to relate and vision "his" needs > > > ***** > In the future the question we ask ourselves will change from "what do I want?" to "what do I want to want?" > And if this does not scare you, you haven't thought about it hard enough. > ***** > > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users

[Users] info on logs regarding tasks..
by Gianluca Cecchi 21 Feb '13

21 Feb '13

Hello, on oVirt 3.2 I successfully tested disk moving for a powered off windows 7 VM (I'm going to try powered on case later). Storage As soon as the operation starts, I can see its details on task section at bottom board. But when it completes I then am unable to see in events any information, for example to track down duration. Any info on where can I find in Webadmin GUI this kind of information? Thanks, Gianluca

[Users] Flush old logs
by Nicolas Ecarnot 21 Feb '13

21 Feb '13

Hi, I'd like first to thank people of this mailing list for there help and advices - I learned a lot by reading your archive. Here's a simple question : In the "Alerts" message queue at the bottom of the screen, I see an error message dating from two weeks (about the failure to verify to restart status of a host). I'm pretty sure this shouldn't be there anymore, as the power management of this host has already been tested and approved many times since. I haven't find any trivial way to flush this message queue, and I was wondering whether it was stored in a database? Is there a way to clear these error messages? (Am I right with the db location?) Regards, -- Nicolas Ecarnot
