[Users] Migrate KVM to Ovirt
by EricD
Hello Guys,
I have a infrastructure of 2 Ubuntu servers that hosts kvm guest.
I want to implement Ovirt, I'm wondering what is the best way to migrate
the existing KVM Guest from my Ubuntu server to Ovirt.
Can i rsync the .img and the xml to Ovirt ?
virt-v2v ?
I want a mention that I have a VM of 800GB would it be to large for Ovirt
or to convert ?

[Users] Add a Host and iptables
by Alexandre Santos
Hi,
I noticed that when I install a new Host using the oVirt Node ISO, when I
try to register my new host on the oVirt Engine, I can't download the
engine key. I must disable the iptables on the engine before.

[Users] Is this "dd" operation harmful?
by Shu Ming
Hi,
I found some "dd" operations were launched contiguously in my vdsm.log.
Is this harmful? How was this operation caused?

[Users] how to convince oVirt a VM is down
by Alan Johnson
One of my hosts died while going into maintenance mode. 2 of the VMs
didn't make it through migration before it became unresponsive. Now, they
are flagged as unknown and I can't do anything with them in that state. I
can't even remove them?
Anyway, is there anyway to convince the engine that a VM is down so I can
bring it back up again, like with "Confirm 'host has been rebooted'" on
hosts?

[Users] Virtual Machine Provisiong
by Marco Mornati
Hello guys,
I'm trying to integrate an automatic provisioning to my oVirt installation.
Something like: API to create VM, NIC and Disk, tool to install SO (??).
I'm actually working around aeolus (after a useless test with koan), but
I'm not sure I can do what I want. I prefer not to use a PXE to get all
things really automatic (something cloud style).
Have you got any idea, suggestion and/or guide about it?
Thanks a lot
Marco

Hi Marco,
From reading through what you're looking for, it seems a good fit for Aeolus.
As well as the points you mention (templates for creations of vm's, with
desired packages, etc), it does a lot more too:
+ VM launching/killing and monitoring
+ Supports several virtualization and cloud platforms simultaneously,
so you build/launch/manage your VM's on (say) oVirt, VMware, and EC2.
OpenStack support (amongst others) is currently being added.
+ You can build custom applications out of several vm templates,
and have them correct pass configuration information amongst
themselves when they launch. (IP addresses, dependency info, etc)
For example, a 2-node Wordpress application, consisting of an Apache
webserver vm template + a MySQL vm template). Automatically sets
itself up at launch:
https://github.com/aeolusproject/audrey/tree/master/examples/wordpress
With the oVirt setup you're doing for those instructions, please try and
use oVirt 3.0 for the moment. There's a bug in an rpm we rely on for our
oVirt support (vdsm floppyinject hook) that's broken with oVirt 3.1.
Hopefully we'll have that issue fixed late next week (enabling oVirt 3.1
support). That doesn't help you right now though. ;)
If it's helpful, the Aeolus dev's are in the #aeolus freenode IRC channel,
and are generally pretty responsive requests for help. i.e. RHEV-M
setup, etc.
We also have an aeolus-users mailing list, which is worth asking on if
you're not in to IRC. :)
https://lists.fedorahosted.org/mailman/listinfo/aeolus-users
Does that help? :)
Regards and best wishes,
Justin Clift

[Users] oVirt MCollective Agent
by Marco Mornati
Hello guys,
I'm working on a cloud provisioning automatic tool and control (
http://www.kermit.fr) and I'm actually creating the module to control the
virtual farm based on oVirt (and RHEV 3.1 when will be out ;)).
That means I created a module to control oVirt using MCollective (
http://docs.puppetlabs.com/mcollective/).
You can find some information about the agent and the usage on my blog,
here: http://blog.mornati.net/2012/10/09/mcollective-ovirt-agent/
And source of the Mcollective oVirt agent here:
https://github.com/thinkfr/mcoplugins (ovirt.rb and ovirt.ddl).
Even if you are not interested in the agent, I think the ruby file could be
useful if you want to use the rbovirt API. I couldn't find any doc about
that API on the net, so I created the agent looking to ruby api sources (I
think any good project should have a little bit of documentation!!!).
Anyway, let me know if you are interested and if you have any suggestion
and idea about it.

[Users] Ovirt live USB - aka oVirt on a stick
by Moran Goldboim
In order To improve the ease of installation, we are working on two new tools:
1. Fedora oVirt spin
We are planning on integrating oVirt to a live fedora spin[1]
This will simplify the the installation for new users. It will contain the oVirt "AllInOne" [2] on top of a Fedora liveCD desktop.
This will allow users to experiment with oVirt before later installing it.
The idea is user will install fedora from the CD, then answer the questions of the all-in-one setup.
2. Simple demo environment
As a second stage, for simple demo use cases, we want to take this one step further.
We'd like to extend this live spin to include a complete environment - sample vm/template/iso/node,etc so that a user can boot from a USB key and have a complete environment that's pre-installed and configured, this will probably will be done with a script calling one of the APIs[3] to create it.
The user would download an image, write it to a USB disk and then boot it[4].
the idea is user can copy this iso to a usb disk (or a qcow/vdmk) and
Once booted the user will have a pre-installed, pre-configured oVirt Engine, host and local storage domain complete with ISOs, VM and template.
any suggestions/help will be appreciated
