We have DEV and QA is the same "data center" but on the network side of
things they are on different switches, so they reused some VLAN IDs.
No problem, my server has 4 NICS.
But how do I tell ovirt its ok to have 2 networks with same vlan ID
because I'm going to put them on different NICs?
It says "specified VLAN ID is already in use".

Dumb question: exclamation mark next to VM?
by Chris Adams
I set up a new oVirt 3.6.2 cluster on CentOS 7.2 (everything up to date
as of yesterday). I created a basic CentOS 7.2 VM with my local
customizations, created a template from it, and then created a VM from
that template.
That new VM has an exclamation mark next to it in the web GUI (between
the up arror for "running" and the "server" icon). Usually I would
expect that means something is wrong or needs attention, but I can't
find anything to fix/address/etc. (no messages in the Alerts, nothing
odd in the Events, etc.). What does the exclamation mark mean, and how
do I clear it?

Coming (Very) Soon - New ovirt.org Website & Deprecated Wiki
by Mikey Ariel
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
In the past months we've been working on upgrading the oVirt project
infrastructure, to better support the community contributions.
One of the main platforms for our user documentation, release
management content, and community content has been the MediaWiki site
that you all know as ovirt.org. Most of us are familiar with the wiki
site format, with all its advantages and disadvantages.
After several years of serving the community, I'm happy to announce
that we are very near to completing a full upgrade of the website
infrastructure from a wiki site to a static site, source-controlled on
GitHub and authored in Markdown.
This email is the pre-launch announcement, as we are reaching the
final stages of the migration, and there are a few actions that might
affect your work on website content in the meantime.
Why migrate the website
=======================
As mentioned, wiki sites provide an open and flexible content editing
platform. Unfortunately, as the site grows the content becomes quite
difficult to manage and curate, resulting in lots of obsolete,
outdated, and incorrect information.
By moving to a source-controlled repository and implementing GitHub's
contribution workflow, we strive to ease the work of maintaining an
up-to-date content site, employ a peer-review process for changes, and
standardize the authoring markup language to lower the contribution
barrier.
The Middleman framework (Ruby-based static site generator) was chosen
based on observing successful implementation of other open-source
community websites, such as OpenStack RDO, Project Atomic, and Gluster.
What we did so far
==================
When we started the migration, our Web design team exported all of the
wiki content from the old website and converted it to MD files. They
also set up the website config flow, auto-deploy, and upgraded the
look-and-feel of the website.
We then initiated a content review effort as well as a UX review for
the new website in a smaller forum, which caught most of the critical
issues with the new website and helped us get the new format to a
place where we can release the website in a near-GA/public-beta format.
Yesterday (Wednesday Feb 17) we exported the website one more time and
currently we're running a diff on all the files that changed since the
initial export was done, to make sure we grab all the updates and the
latest content before we launch the new website.
What is about to happen
=======================
Today we are initiating a **wiki freeze**, which means the old
MediaWiki site will become read-only. This is to ensure that all of
our diff scripts reflect the most current state of the content on the
website, and that we don't lose any content in the transition.
Barring any unexpected blockers, we will port the ovirt.org domain to
point to the new website and open the new website for contributions on
**Monday February 22** or earlier.
What do you need to do right now
================================
If you have any wiki pages that you're actively editing, please don't
save them to the old MediaWiki site, and hold onto your pending
changes until we send the happy launch email.
We will also include instructions on how to contribute/edit/add
content to the new website, but in general the workflow will be
aligned with the standard GitHub best practices
(clone-edit-commit-pullrequest), so you can utilize all of the git
commands that you already know or work directly within the GitHub web
editor.
I'd like to thank all of the people who were involved with this
migration so far, ovirt.org is a big website with lots of content and
it was no small task to upgrade it.
Please feel free to ping me on- or off-list if you have any questions
about the next steps, and expect a happy launch email soon!
Cheers,
Mikey

Perhaps you do not have an IP address on that interface? You do need one.
The engine will communicate with the host using this address.

Sorry for that. Bugs/RFEs/patches are always welcome :-)

Because of the way the deploy script is currently implemented, it would be
hard to completely undo changes on failure (which we do try hard in
engine-setup). We have an open RFE for supplying a cleanup tool:
https://bugzilla.redhat.com/show_bug.cgi?id=1001181
See also:
http://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-from-fa...
The source package also has:
https://gerrit.ovirt.org/gitweb?p=ovirt-hosted-engine-setup.git;a=blob;f=...
It's currently down for some reason, not sure. A mirror is available at:
https://github.com/oVirt/ovirt-hosted-engine-setup/blob/master/cleanup.sh
All of these are far from perfect, and reinstalling the OS is way safer
when trying to debug such issues.

Again, not sure what the exact problem was. Please post setup logs.

Not that I am aware of.
loopback-mounting nfs is considered unsafe due to locking issues, see:
https://lwn.net/Articles/595652/
You can use iSCSI.
Most people install it on more than one machine. For a single machine,
usually virt-manager is enough.
Of course you can use VMs with nested-kvm to virtualize more than one
machine on a single one, if you mainly do this for testing/learning/etc.

Proper support is currently partial. Search the net for e.g. 'ovirt
hyperconvergence' for the current efforts. The plan is to require at
least 3 physical machines, to have a replica-3 gluster storage and
quorum. It should be possible today to deploy on a single machine with
gluster, supplying three different paths for gluster all on the same
machine.
For best results, currently, you should have at least 3 machines:
One for storage (or a dedicated storage appliance), two for hosted-engine
hosts providing high-availability.
Best regards,

Shutdown Problems on oVirt Node
by Roger Meier
Hi their
I have currently a strange problem on a new oVirt 3.6 installation. At
the moment a clean shutdown doesn't work, most of the time he reboots
the system or hangs in the shutdown progress.
I discovered this, when i tested our multiple UPS solution and send some
test signals over ipmi to our server with ex. ipmipower -h 192.168.2.218
-u root -p password --soft . We also discovered that shutdown -h now ,
poweroff or init 0 had the same effect.
On a clean CentOS installation, which is not included in our oVirt setup
this works as expected, but on our ovirt-node this doesn't work.
In the shutdown progress i see the following which tooks very long:
> A stop job is running for Shared Storage Lease Manager (23s / 1min 47s)
At the end i had then the following on my console screen:
[ OK ] Reached target Shutdown
Nothing more happens. no poweroff or something. I can wait more than
three minutes and nothing happens.
I also tried a clean re-install from the oVirt Administration WebUI but
this doesn't have any effect on this issue.
When i type "service sanlock stop" or "service vdsmd stop" in the server
console and then do a poweroff , all works as expected. The shutdown is
the also realy fast as expected.
At the moment we think that the problem is on ovirt, vdsmd or on the
sanlock settings for ovirt, because all settings on our site are on
default settings.
Currently Setup are two Intel Server (With RRM) with CentOS-7 (1511) and
oVirt 3.6.3 and one Intel Server with OpenIndiana which provides Storage
via NFS.
Had someone a solution for this? is this perhaps a bug and shoul'd be
reported?
Greetings

Welcome: New ovirt.org website!
by Mikey Ariel
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
Following yesterday's pre-launch email[1], I'm happy to announce that
the new ovirt.org[2] website is now live in **public beta** and
available for community review.
All the information in this email is also available in the first blog
post of our shiny new oVirt blog[3]. Read on for information about new
features, known issues, and a call for reviews.
The old MediaWiki site is still available in read-only[4], and will be
taken offline on **March 1, 2016**. This is to ensure that you can
compare pages and review migrated content.
What's New
==========
The new Website is full of improvements and enhancements, check out
these highlights:
* Source content is now formatted in Markdown instead of MediaWiki.
This means that you can create and edit documentation, blog posts, and
feature pages with the same Markdown syntax you know.
* The Website is deployed with Middleman and stored on GitHub. This
means that you can make changes to content with the same GitHub
contribution workflow that you know (fork, clone, edit, commit, submit
pull request). We even have an "Edit this page on GitHub" link at the
bottom of every page!
* New layout and design, from breadcrumbs to sidebards and an upgraded
landing page. (This is still WIP, please see known issues.)
* Automatic redirects from the old MediaWiki site. This means that if
the wiki page exists in the new website, previously-released URLs will
redirect to that page. If the page was removed, the Search page will
open with the page title auto-filled in the search box.
* Hierarchical content structure. This means that instead of flat
Wiki-style files, the deployed Website reflects an organized source
repo with content sorted into directories and sub-directories.
* Official oVirt blog! Our new blog welcomes contributions. This means
that if you solved a problem with oVirt, want to share your oVirt
story, or describe a cool integration, you can submit a pull request
with a blog post and we will provide editorial reviews and help
publish your posts.
* Standardized contribution process. The GitHub repo now includes a
README.md[5] file that you can use to learn about how to add and edit
content on the website. We welcome pull requests!
Known Issues
============
Despite our best efforts, there are still a few kinks with the new
website that you should be aware of:
* Attempting to navigate to ovirt.org (without www.) leads to a
redirect loop. We have a ticket open with OpenShift, our hosting
service to fix this.
* Only http is available. We also have a ticket with OpenShift to add
SSL and enable https.
* Home page and Download page are still being upgraded by our UX
experts, expect some cool new changes soon!
* Feature pages look-and-feel is still under construction. You can
still edit and push feature pages as usual.
What's Next
===========
Even though the Website is live, the work is hardly over. We'd like to
ask for your help in:
* Reviewing content for anything obsolete or outdated (each page in
the new website includes a header toolbar with metadata from the
original wiki page for your convenience)
* Submitting blog posts or any other content that you wish to share
with the oVirt community
* Reporting bugs and proposing enhancements, for example broken links
or missing pages
We hope you will enjoy the new oVirt Website, looking forward to your
feedback and contributions!

Several docs are contradictory about NetworkManager on the engine.
Do we have to disable it in 3.6.3? (we're using CentOS 7.2)
Thank you.
