As part of our efforts to raise awareness of and educate more developers
about the oVirt project, we will be holding an oVirt workshop at
LinuxCon Japan, taking place on June 8, 2012. You can find full details
of the workshop agenda on the LinuxCon Japan site. 
Registration for the workshop is now open and is free of charge for the
first 50 participants. We will also look at adding additional
participant slots to the workshop based on demand.
Attendees who register for LinuxCon Japan via the workshop registration
link  will also be eligible for a discount on their LinuxCon Japan
Please spread the word to folks you think would find the workshop
useful. If they have already registered for LinuxCon Japan, they can
simply edit their existing registration to include the workshop.

I am trying to run engine-setup utility on rhels6.2 machines to configure ovirt-engine but get an error while starting jboss. (Exception: Error while updating jboss ROOT.war directory) Any ideas what is happening? Thanks
oVirt Engine will be installed using the following configuration:
org-name: NASA LaRC
Proceed with the configuration listed above? (yes|no): yes
Configuring oVirt-engine... [ DONE ]
Creating CA... [ DONE ]

What is the proper process for this in ovirt? Or has someone done it

I'm attempting to fine-tune the process of getting my KVM/Libvirt
managed VMs over into my new oVirt infrastructure, and the virt-v2v
import is failing in the WUI with "Failed to read VM 'dh-imager01'
OVF, it may be corrupted". I've attached both engine and vdsm logs
that are a snapshot from when I ran the virt-v2v command until I saw
the failure under Events.
virt-v2v command used...
# virt-v2v -i libvirtxml -o rhev -os
virt-v2v: dh-imager01 configured with virtio drivers.
The xml has been modified numerous times based on past mailing list
comments to have VNC and Network information removed, but still the
same failure. I've attached the latest XML that was used in the log's
failure as dh-imager01.xml. I've also tried passing hte bridge device
(ovirtmgmt) in the above command with same failure results.
Node and Engine are both CentOS 6.2, with vdsm-4.10.0-4 and
Please let me know what other configuration information could be
helpful to debug / troubleshoot this.
Are there any other methods besides a virt-v2v migration that can
allow me to use my previous KVM VMs within oVirt?
Last week I pitched the idea of having some demo videos (I called them
"screencasts" although that's not quite accurate) ready before the 3.1
release next week.
I don't have the domain knowledge to do this myself, so I need your help!
What is there to do?
1. Go to http://wiki.ovirt.org/wiki/Screencasts - have a look at the
features I've proposed for the first round of videos. If you really
think one of them shouldn't be there, or there's a really important
feature you'd like to see a demo for, please reply here and we'll
discuss it. You can always add a proposed feature with the skeleton
template to the Screencasts page also, but there's no guarantee we'll
have a video by the time the release comes around. It would helkp me
prioritise if we could gather feedback here.
2. For each feature, we should have a scenario/script for the demo,
* Required pre-requisites and set-up (what do I need to do before I
start the demo)
* A step by step description of how to show the feature being demoed
Right now, only two features are described, and those descriptions may
If you see a feature which is not yet described, and you know how to use
it, please add a little script following the template. If you see a
feature which is not described well enough, please update the description.
3. For each feature with a script, we need a video. I have started a
page to help people record videos of their screen, for the systems I
know about: http://wiki.ovirt.org/wiki/Recording_video - the videos
(without sound) can, I think, be attached to the wiki page - ogv or webm
format preferably, please!
4. For each video, we will need a sound-track. I'm happy to voice over
some of the videos, but again, it would be nice to spread the load.
We're not even here yet, though.
Thanks everyone for your help! It will be greatly appreciated.

I have an environment where I would like to be able to provide users
with a single web interface from which they would be able to open a
console on either a virtual machine or on a physical machine. Playing
with a clean install of oVirt 3.1 suggests that oVirt is not capable
of doing this.
Has anyone successfully configured oVirt to provide this capability,
or know of a system that could integrate with oVirt to meet that
In some setups, like when you got two datacenters that works like failover sites, you would like to have two external raid controllers(storage devices), one in each datacenter.
You then send two identical LUN's, from each controller, to a cluster, let's say two hosts, for simplicity. What you normally do is to host raid these LUN's in mirror(raid 1), so the hosts write the same to both LUN's, and both controllers.
Question for me here is if I can accomplish this in oVirt management? Because if I can't, it will be a problem, because if I host raid at the host level, then the storage would be local storage for oVirt, wouldn't it? And then I suppose it can't be used for live migration, can it?
