Thanks a lot for your answer.
It's more HA then disaster recovery. If 1 storage is down, it should be 
possible to use the second one without a downtime.
So Geo repolication of Gluster isn't really what we are looking for. The 
storages are also located in 2 different buildings with redundant network and 
FC connections and low latency.
According to your answer I guess LVM mirroring isn't possible, right?
Do you think using the FC LUNs as Gluster bricks could be a reasonable solution?
We have 2 storages with multiple LUNs, 4 oVirt hosts and 2 atm non used hosts, 
so a distributed replicated volume with arbiter or replicated with arbiter 
could also be possible to replicated the 2 storages, I think.
But I'm concerned about performance, as I don't have good experience with 
Gluster on VMware when using 1 VMDK (hosted on a NetApp storage with 10K SAS 
disks), but good experience with Gluster when using 12 (or 24) local SATA disks 
in a host. So I fear that 1 LUN from a storage (ZFS storage with a pool of many 
disks) is not as good as 12 local disks in a storage.

[ovirt-users] LVM Mirroring

[René Koch]

Hi list,

Is it possible to use LVM mirroring for FC LUNs in oVirt 4.2?
I've 2 FC storages which do not have a replication functionality. So the idea 
is to create a LVM mirror using 1 LUN of storage 1 und 1 LUN of storage 2 for 
replicating data between the storages on host level (full RHEL 7.5 not oVirt 
Node). With e.g. pacemaker and plain KVM this works fine. Is it possible to 
have the same setup with oVirt 4.2?
Thanks a lot.

René

For best multimedia performance a resonable graphics card and cpu in
your thin client is needed and up-to-date remote viewer version.

I used thin clients from IGEL in many setups. If you want good
multimedia performance (watching full HD videos in your vm) you need
the UD5. IGEL is a good solution when it comes to managing thin clients
as they have a great management server for it. The downside is that
IGEL thin clients aren't really cheap and remote viewer comes in a
quite old version.

One of my customers uses Intel NUC devices with Fedora on it (PXE boot)
and has a much better performance as with IGEL UD5, but to be fair he
compared it with the 5 year old UD5 model. This is mainly because of
the newer processors in Intel NUC and new virt-viewer of Fedora.

Hope this helps.

René

Re: [ovirt-users] nagios for ovirt 4

[René Koch]

Hi,

Latest version from master branch will work, as it contains support for 
both API versions.
I (sadly) didn't had enough time yet to release a new stable version 
with support for oVirt 4.0, so please use plugin from master branch. Thanks.

Self replying.
Latest version of https://github.com/ovido/check_rhev3
 works fine


From what I can see, it might not work with oVirt 4.x, due to outdated 
API endpoint[1].

I've opened an issue[2] about it.
Y.

Re: [ovirt-users] Prepare for version 4 of oVirt API

Hello all,

For those of you that use oVirt API, I wanted to inform you that
version 4 of oVirt will by default use a new version of the API,
incompatible with the previous one. The previous version will still be
supported, but only for clients that explicitly send the "Version: 3"
header, as described here:


https://github.com/oVirt/ovirt-engine/tree/master/backend/manager/modules/restapi
So with version 3 everything should work in futher version of oVirt, but 
it's recommended to switch to Version 4, right? Are there any plans yet 
to drop support of Version 3 API in e.g. oVirt 4.1?


If you are aware of any piece of software that uses the oVirt API,
please let me know, so that we can inform the authors.
Thanks for sending a patch to check_rhev3, I've merged it into master. 
So monitoring oVirt 4.0 with Nagios/Icinga should work :)


Thanks in advance,
Juan Hernandez

Hi Mikey,

The new page looks really good.

I figured out, that all of the links to presentations and templates are 
still pointing to the old Mediawiki url and so all presentations are 
unavailable:

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!

[ovirt-users] ovirt-guest-agent puppet module available for testing

[René Koch]

Hi,

As I'm trying to manage my infrastructure using puppet, I figured out 
that there's no puppet module available for installing and configuring 
ovirt-guest-agent (or at least I couldn't find one). So I created a 
module, which is tested on Debian 7/8 (please see Readme for 
limitations) and CentOS/Scientifc Linux/RHEL 6/7. Other operating 
systems will follow soon...


If you're using puppet, feel free to test this module and leave me some 
feedback:

René

Re: [ovirt-users] Run Once install -> reboot loop

[René Koch]

Hi Jamie,

That reason for this is, that the iso will be mounted as long as you're 
in run once mode.


You can fix this by powering off your vm after the installation and run 
it again in "normal" mode. As you don't want to run the vm in run once 
mode forever, you have to shut it down anyway.

René

Hello all,

I’m running overt 3.6.0 on Centos 7.[1]

I’ve been working on getting Ovirt to slot in to our environment, and almost 
have a setup that works. I can now build isos on demand for automated installs 
(I’m working around some local networking choices without modifying them for 
now, which is why this isn’t a PXE boot) and create my guests, pointing them to 
the iso form which to install via Run Once. This all works.

The problem is that after the install, the guest reboots, but (best I can tell) 
Ovirt doesn’t detect it, the iso is still mounted, and the install happens all 
over again. Rinse, repeat.

Has anyone seen this? Or better, does anyone know how to fix this?

Re: [ovirt-users] Monitor with nagios

[René Koch]

Hi,

If you don't want to install any agents like snmpd or nrpe and plugins on your 
hosts, you can monitor some basic metrics like cpu, memory, status, nics,... of 
your hosts with check_rhev3, as Dominique already mentioned. See the 
documentation about what's possible at the moment: 
https://github.com/ovido/check_rhev3/wiki/Usage-Documentation

If you're missing something, this plugin doesn't provide yet (but is possible 
to fetch using oVirt's REST-API), please let me know and I'll update the plugin.

René

Hello!

I think it depends all on what you do want to monitor. 

a simple PING check is the least you should do, but this often is
not enough.

You can check the management modules of your hosts for hardware
issues (iDRAC, ILO, IMM, ...) via nagios.

In Addition to that, you can install a nagios (NRPE) client on your
hypervisor, if you are running CentOS/RHEL/Fedora and perform some
checks via this client.

In addition to that, we do have check_rhev3 (https://github.com/ovid
o/check_rhev3) running against our engine hosts to monitor various
elements like status of host/cluster/network etc of our oVirt
infrastructure.

best,
 Dominique

Re: [ovirt-users] VDI non-persistant desktops

[René Koch]

Hi Colin, 

I normally use desktop pools for virtual machines, which are the same, and 
single desktops for individual vms. 
So mostly office vms are from a pool and admin vms aren't. 

For patching you can either use some tools like Microsoft WSUS or for Linux vms 
Katello/Satellite/... or if you're using desktop pools it's also possible to 
patch the master image, create a new template with a new version and shut down 
all you vms. Afterwards they should boot with the new version if you did 
configure to always use the lastest version. 

Performance of the virtual desktops depends on some things: 
- protocol (Spice is really great in our tests) - also make sure you install 
all VirtIO drivers in your vms 
- bandwith - this is no problem in the LAN, but for WAN setups this could be an 
issue. Watching full HD videos in your vms can require 40mbit/s... 
- thin clients - they need good graphics cards and at least 2gb ram and 2 cpu 
cores, better 4... 

Most of my customers use GPOs for their virtual desktops, as it's easier to 
configure group policies then updating the master template too often... 

I hope this helps...

René

Hi all 
We're using RHEV 3.5.7 and have about 40 desktop VMs that are all clones from a 
single original. 

In the very beginning we used desktop pools but this was torn down when we 
started getting "The trust relationship between this workstation and the 
primary domain failed" error messages. 

We use DHCP for all desktops however every VM is defined on the DHCP server and 
unknown MACs are rejected. 

I'd like to revisit desktop pools but I'd like to know if other are using this 
and what their experiences have been. 

Kind of thing I'd like to know is 
- how is patching done 
- what is the performance like 
- what tuning if any is done on the desktops 
- GPO vs LPO 

Any comments? 

Thanks

Re: [ovirt-users] Mixing CPU types

[René Koch]

Hi Neil,

You can mix cpu types (but not AMD and Intel) if you leave the cluster 
level at the lowest cpu level.
I personally don't mix cpu levels if possible, but instead create own 
clusters for each cpu type in order to be able to use the newest cpu 
features...

Hi guys,

Can I mix CPU types (Haswell and Sandy Bridge) in my cluster and will 
I be able to migrate between my hosts?


I'm guessing that for this to work I'll need to leave my "CPU type" 
set to Sandy Bridge, will the Haswell based CPU be compatible with my 
cluster, but just run without any Haswell type features?


Apologies if this is a dumb question or if it's been answered before.

Re: [ovirt-users] Ovirt supported thinclient appliance

[René Koch]

Hi, 

There aren't too many thin clients out there which support oVirt/RHEV. 

I did a few VDI projects with oVirt and RHEV and I can recommend the Igel UD5 
Thin Client: 
https://www.igel.com/en/products/igel-thin-clients/ud5-series.html 

It's not the cheapest one and not the smallest one, but has good performance 
and the management software for these thin clients is great.

Re: [ovirt-users] oVirt management network

Hi Bojan,
















Did you configure a VLAN tag für your ovirtmgmt interface?







You have to do this in „Data Centers“ – select dc – „Logical Networks“.







Afterwards you should be able to configure network from oVirt webadmin 
interface again.







Don’t have a test setup with VLAN tags for ovirtmgmt atm, but did this multiple 
times before…

Betreff:
 [ovirt-users] oVirt management network

















Hello, I am having a strange issue in creating ovirtmgmt bridge over vlan 
interface.



I have set-up a bond from physical interfaces. On top of a bond there are three 
VLANs one of which is in ovirtmgmt bridge. I have set it up manually according 
to 
http://www.ovirt.org/Bonding_VLAN_Bridge




Somehow the bond itself is also added to bridge in oVirt web interface, after 
reboot there also were two added lines to configuration of that bond:

# Generated by VDSM version 4.16.10-8.gitc937927.el7

BRIDGE=ovirtmgmt



No matter how I try to remove the bond from the bridge it doesn't succeed. If I 
edit the config files manually it isn't replicated to web interface. If I try 
to detach it from web interface, I can only attach bridge back to the bond 
interface. Of course configuration cannot be saved until the bridge is attached 
to an interface.



I have tried putting the host in maintenance mode, shutting down the hosted 
engine and doing all the changes live.



Anyone has a suggestion how to resolve this?



Thanks.

Hello

I'm a new guy in ovirt 3.3.5, I try to change a pool's template. When
I edit the pool, the option Based of Template is gay. How to do
that? I don't want to delete and rebuild again.



you cannot change pool's template, because it means replacing all the disks for 
all the vms in the pool,
which is basically the same as removing the pool and creating a new one.

but, you can do something similar in 3.4, using template versions:
in 3.4, when you create the pool, you can select a template and LATEST as the 
version.
when you create a new template, you can make it a version of the original 
template,
and the pool will update to this template.


I tried this features with oVirt 3.4.1, but it didn't work as expected.

When selecting latest and a guest is shut down it will be deleted.
The expected behavior would be that a new vm with the newest version of 
this template (latest subtemplate) would be started.


The actual behavior is the following: VM will be deleted, pool is 
decreased by 1 vm and vm is started as a standalone (desktop) vm.


So the whole pool features is broken when using latest template feature 
(in 3.4.1 - didn't test it with 3.4.2 yet).

René

Re: [ovirt-users] Get involved in oVirt integration! June edition

[René Koch]

Hi Sandro,

Sadly I don't have time to work on one of these bugs, but I have a 
general question on how contributing to oVirt works. [2] explains in 
detail how to push code to gerrit.


As I wanted to start contributing to oVirt I started with the easiest 
way by extending the list of operating systems. So I created a bug for 
this (1101219), pushed to code to gerrit (referenced to this bug id) and 
Jenkins build job was successful. So I did everything mentioned in [2] - 
but what now?


Shall I just wait and see what happens?
Should I post to ovirt-devel that someone will review the code?
Who decides which oVirt version will include this code or if this code 
will be included or needs adaptions (I only know that a certain score in 
gerrit is required and some developers are allowed to rate a commit)?


I'm aware that my commit isn't fancy at all and there's no need for any 
priority, but just want to know what's the right workflow in case I have 
more time to work on some bugs...


I guess these questions could be interesting for users (basically for 
users who are not familiar with a professional development 
setup/workflow including gerrit like me) who want to work on the bugs in 
june edition as well...



Thanks,
René

[ovirt-users] Issue / strange behavior with GlusterFS nodes

[René Koch]

Hi,

I have the following oVirt setup:
2 storage hosts with GlusterFS (replicated) - will be extended to 4 
hosts (distributed-replicated)

4 virtualization hosts
1 datacenter
2 clusters (1 only for virtualization, 1 only for GlusterFS)

The strange thing is now:
One of the 2 GlusterFS hosts (these hosts and the Gluster volumes are 
managed by oVirt) fails to mount one of the storage domains, but I can 
mount it manually.


So the first question is: why should these hosts mount the storage 
domains? They are in a cluster without virtualization, so it's not 
possible to run virtual machines on these hosts. I think they try to 
mount the storage domains because the storage domains are attached to 
the data center, but imho the cluster should be checked as well if 
virtualization is enabled.


So I was thinking of moving the GlusterFS cluster to a new data center 
without storage domains, but this is impossible as Gluster volumes are 
created. The only possibility would be to remove the Gluster volume.


So do you have any idea how I can solve this issue? I mean the Gluster 
volume is working fine, but it's really disturbing that I get an error 
message every 5 minutes.


Thanks!

Just to let you know you're not the only one with this problem. I have
had it too a couple of times and still don't know the right
incantation to get rid of it. I have the same setup: 2 clusters,
storage and virt, 2 nodes each, one datacenter. Currently on 3.4.1 and
had the problem on the 3.2/3 series. For me it seemed related to
upgrading but that could be just chance. It might as well be related
to a complete shutdown/restart of all machines ( this test setup is
not behind a ups which gives some rare opportunities to troubleshoot
problems :-) )



Yes, this is a bug I would think. For a gluster only cluster, the
storage domain is not relevant.

Could you log a bug with the error attached, and we will try to fix
this. If it's a simple enough fix, we could backport it to 3.4


Done: https://bugzilla.redhat.com/show_bug.cgi?id=1105513

I used component vdsm, but maybe it should belong to webadmin - I'm a 
bit unsure which component is responsible for this.

Re: [ovirt-users] Spam Re: Spam Windows guest agent

[René Koch]

Hi,

installing is quite simple:

1. Install SPICE Windows guest tools from 
http://www.spice-space.org/download.html - this also install 
virtio-serial driver, which are required for the next steps


2. Follow this guide: http://www.ovirt.org/OVirt_Guest_Agent_For_Windows

If you can't start the service the issue may be because of missing 
virtio-serial drivers. If you're sure they are installed, reboot the vm 
as Windows sometimes requires a reboot for drivers to work properly.


If you want single-sign-on feature please let me know how you managed to 
do this, as I don't know it myself...



Regards,
René

   Is there some special trick to get the windows guest agent to
install properly? I have the service installed but it wont start.
Perhaps someone made a youtube video of the install. I saw some prior
posts where other were having issues but when they asked for helped they
got the old RTFM answer. The problem is the FM seems to be missing some
steps. Any help would be appreciated. Thanks

You have to be in ovirt-guest-agent/ovirt-guest-agent and in this 
directoy is a setup.py (and also the README-windows.txt as mentioned in 
oVirt wiki) file. It worked for me the last time I did this - haven't 
tried it today...




Just copying the parent dir to 'Program Files' and execute what is in
the README will work though. Thats how I have done it all the time.

I suggest to try the shiny new ovirt-guest-tools iso. You can find more info

Cool, didn't know that there's already an ISO available.

I just tried it and oVirt Guest Tools Installers says Unsupported 
Windows version for my Windows Server 2012 R2 vm. Is this known or 
should I open a bugreport for this?

That's the path to the folder on your host which should contain your vm 
disk files. If you want your vm disks under /data/vms then use this path.


Just make sure the path exists, no files are in this directory and that 
it is writable by 36:36 (vdsm:kvm).

Did you try the native client on Debian? Maybe the spice-xpi version is 
too old - if you don't see the menu it's a quite old spice-xpi version.


During my tests it was only possible to automatically mount USB devices

The policy is to keep the currently set value - the value is not being reset to 
the new default when updating the selinux policy (as you assumed). So if you 
did update It should be still off.


Ok, thanks for the information.
I did add the solution (set boolean manually to on) to the bug report

[ovirt-users] Monitoring UI-Plugin - Zabbix

[René Koch]

Hi,

As some of you might know I wrote a monitoring ui-plugin which displays 
the check results of a Nagios/Icinga monitoring solution in oVirt 
webadmin portal.


For the next version I want to extend the functionality to also display 
check results of a Zabbix monitoring solution. I know that there are 
some people on this list who are experienced with Zabbix so I wanted to 
ask if there's someone who want's to help integrating Zabbix into this 
ui-plugin. I mostly need help understanding how Zabbix works and testing 
early versions (I just have a very small Zabbix monitoring environment) 
- fetching data from the Zabbix API and displaying it in the same way as 
Nagios data isn't a problem for me.


So if you're willing to help please drop me an email. Thanks.

As I already wrote to you you have to put the host into maintenance mode

virtualization is always a mistake you will regret latter. Its a
common (almost default) mistake people who are just getting started
with virtualization make. Fibre (which includes optical fiber and
copper using the same protocols ) channel at best or a pNFS or
Gluster solution will server you a lot better as long as you have a
decent number of spindles and a lot of ram for cache on the storage
servers/controllers.

How do i do this?

For example in this screenshot, no way to configure local storage

Re: [ovirt-users] oVirt All-In-One instructions for presentation?

[René Koch]

Hi Greg,

I do have a slide set for an 3 hour oVirt workshop (atm only German as I 
didn't had enough time to translate the slides into English), but I 
think this is not what you're looking for...

René

Hi,

I submitted a tutorial proposal to LISA '14 called Hands-on with oVirt, but it was 
rejected. However, we can still get oVirt in front of people if we rework it as a lab.

Basically a lab is just a one or two sheet set of instructions that would 
describe to someone how to test out oVirt All-In-One in the LISA lab.

I know there have been demos of oVirt all-in-one at other conferences. Does 
anyone have a list of presentation-friendly instructions that he/she could 
share?

Thanks!
Greg

PS -- Actually -- the 'demo' doesn't have to be all-in-one, but I was thinking 
that would be easiest given the unknown lab hardware at LISA. If the lab is 
very powerful, I suppose attendees could try to setup separate nodes. I'll try 
to find out lab details.

Re: [ovirt-users] oVirt Infiniband Support - Etherrnet vs Infiniband

Hello List,

i am very new to ovirt. I am setting up a 2 Node Cluster with GlusterFS
Sync Replication.

I was about to buy a 2-Port Intel Gbit nic for each host which is about
150Eur each.

However, for a little extra of 180Eur you get a 10GBit Infiniband -
MCX311A-XCAT.

I would like to have quick opinions on this.

Should i pay a little more and then get 10MBit instead of 2GBit bonded?


Infiniband is good for GlusterFS / storage connection but never never 
never never ever use it as a vm network - believe me it's a nightmare.


So you would direct connect your 2 nodes as otherwise you would have to 
buy an Infiniband switch as well (btw I'm not sure if direct connect is 
possible, but I guess it is). Keep in mind that Infiniband cables aren't 
cheap, too.

Why don't you go for 10Gbit/s Ethernet?



Thanks,

Re: [ovirt-users] Server 2012 R2 no drive found

[René Koch]

Hi Neil,

I'll test Windows Server 2012 R2 again with IDE and VirtIO disks (and 
e1000 and VirtIO network cards) with VirtIO-drivers from RHEL channel 
and drivers bundles with spice guest agent and will let you know the 
results. Please keep in mind that it will take some time...

Btw, I will use Windows 2012 R2 english, 180-days trial...

Hi guys,

Is anyone able to assist here? I still can't install 2012 R2, whether
I use IDE, virtio, or virtio-scsi, I don't see a drive during the
first install.

I've tried the virtio-win-1.6.8/vioserial/2k12R2/amd64 as a test and
this also doesn't work, so it doesn't seem like a driver issue, more
of a cluster issue.

I've also tried changing my Datacenter compatibility and Cluster to
3.4, but this seemed to make no difference. Both my hosts are upgraded
to Centos 6.5 all updates, as well as my ovirt and VDSM is updated to
the latest stable 3.4 packages.

I'm at a loss here, but desperately need to get this R2 installed.

Further to what Paul mentioned below, this was upgraded from 3.1 so it
doesn't just appear to happen to new 3.4 installs.

Any help is greatly appreciated.

Hi guys,

Thanks for the replies.

What's strange is that even when choosing an IDE disk I don't see any
hard drive showing up when I try to install 2012R2, is this normal? I
can understand why R2 won't see the virtio scsi disk, but to me it
should be showing up when using IDE, or am I wrong here?

I see that in the virtio drivers from RHEL supplementary there is a
folder virtio-win-1.6.8/vioserial/2k12R2/amd64 but the license seems
to indicate that you need a valid subscription in order to use these
drivers... if this is true then is no one using server 2012 R2 on
oVirt without a valid subscription?

I see with the drivers from
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/src/;
there is only a Win8 driver, and trying to use this on my 2012 R2
doesn't find a matching driver.

Can anyone clarify this from Redhat? If you using RHEV, presumably you
can use R2, but it seems using oVirt you aren't allowed to?

Thanks.

Well i just want each physical node to have some independencies. I will

What does glusterfs does actually? I have heard of it but never really

With GlusterFS you can create a NAS out of standard x86 hardware. E.g. 
you have 4 nodes with 1TB of local storage each you create a 
distributed-replicated GlusterFS-volume which has a size of 2TB, but it 
still works fine even if 2 nodes fail.


See gluster.org for more detailed information: http://www.gluster.org/about/




Also PLEASE how do i go ahead and setup ovirt to use the LOCAL STORAGE
of the physical nodes?


Simply put your host into maintenance mode (Host - Maintenance) and 
select Configure Local Storage afterwards. You have to specify a 
folder which should contain your vm disk images on this host and oVirt 
configures the storage domain for you.

Sure you can use the Local storage feature.

What's the reason you don't want NFS? IS it because you don't want
to have a dedicated storage or because you want to separate your vm
storages? If it's the dedicated storage you could have a look at
GlusterFS, otherwise you can for sure use the local disks.



Can ovirt do this?
It is ok to have ISO images on the ovirt-engine/management host
but i do
not want NFS or Shared storage when it comes to the hosts in the
infrastructure.


In oVirt 3.4.1 you have to use either NFS or POSIXFS - so there's a
need for a NAS...


Please advice.

Subject: [ovirt-users] Creating a VM for Ubuntu 14 (Trusty Tahr)

Hi,

I notice that when creating a new VM and selecting the OS there is no
choice available for Ubuntu 14.04 Trusty Tahr at this time.
How much difference does the OS selection make? Would I be safer
choosing Ubuntu 13.10 Saucy Salamander or Other?


I choose Ubuntu 13.10 for my Ubuntu 14.04 Test-VMs and it works fine.

It shouldn't matter if you choose Ubuntu 12.04, 12.10, 13.04 or 13.10 as 
all OS types have the same values.


If you want Ubuntu 14.04 in your OS selection create the following file:
# vi /etc/ovirt-engine/osinfo.conf.d/01-ubuntu.properties
os.ubuntu_14_04.id.value = 1256
os.ubuntu_14_04.name.value = Ubuntu Trusty Tahr LTS
os.ubuntu_14_04.derivedFrom.value = ubuntu_13_10

and restart oVirt engine:
# service ovirt-engine restart


Regards,
René






you can see the difference of OS settings in
share/ovirt-engine/conf/osinfo-defaults.properties

from a quick look, there is no big difference (in settings) between different 
versions of Ubuntu
so i think you can safely select the latest there


Thanks,
  Bob

I faced the same issue this week where jpackage.org isn' resolvable by

A common problem these days.

Re: [ovirt-users] How to install spice-xpi-2.8 on ubuntu12.04?

[René Koch]

Sorry for my late response - I was on an event from thursday till saturday.

I did the following to make Spice working on Ubuntu 12.04/12.10:
# apt-get install spice-client
# dpkg -i spice-xpi_*

But it was an older Firefox version, so maybe it's not working anymore. 
Sadly I can't test right now as I don't have any Ubuntu client here 
(anymore).

[ovirt-users] Open source events in Austria - summary/feedback

[René Koch]

Hi,

As you might have noticed/read there were 2 events in Austria with oVirt 
presence:



* Grazer Linuxtage from April, 4th till April 5th in Graz
-

Grazer Linuxtage had a new visitor record of 800 participants on 
Saturday (100 during the workshops on Friday) and oVirt was represented 
by Peter Stöckl (Solution Architect at LIS-Linuxland GmbH), Frantisek 
Kobzik (oVirt developer at Red Hat) and me.


On April, 4th the oVirt workshop took place (with 6 other workshops at 
the same time). In this workshop with 20 participants the following 
topics where covered in 3 hours:

- What is oVirt?
- Installation of oVirt engine
- Installation of oVirt hosts
- Storage domain configuration (data, iso and export)
- Network configuration
- Installation of virtual machines from ISOs
- Live migration of these virtual machines
- Creation of snapshots
- Export and (re)import of virtual machines
- Maintenance Mode of hosts and storage domains

Every participant received a Live-USB-stick with oVirt 3.4, which was 
used as a host in our oVirt workshop setup. So we ended up with 20 hosts 
in 1 datacenter...


Here are the workshop slides if you're interested in:

* http://glt14-programm.linuxtage.at/attachments/143_oVirt%20Workshop.pdf

At the moment they are German only, but I'll translate the slides and 
make them available for everyone who plans to do a workshop as well.



On April, 5th I had a talk about new features of oVirt  with approx. 
40 participants which covered:

- What is oVirt
- What's new in oVirt 3.3
- What's new in oVirt 3.4
- oVirt extension (Monitoring with check_rhev3 and Monitoring UI-Plugin)

The reason for the small amount of participants was definitely the fact 
that oVirt isn't well known enough here in Austria (so I guess I have to 
do some homework :) ).


If you understand German you can have a look at the slides and the video 
of the talk:

* 
https://www.youtube.com/watch?v=4RvHK8GUO5sindex=12list=PLWHx0EvwLLUHaDLeRf7bHoVjy9wx7IbbB


Also on April, 5th we had the oVirt stand where Peter, Frantisek and I 
had many talks with interested people and received good feedback and 
also feature requests. The most asked features are:

- Support for Linux container (lxc)
- Support for ARM cpus
- Support for Debian (host and engine)


Last but not least some impressions from the Grazer Linuxtage event:

* https://www.flickr.com/photos/62816961@N00/sets/7215764460467/
* http://linuxtage.at/galerie/




* Linuxwochen Wien from May, 8th till May 11th in Vienna
-

oVirt was represented by Peter Stöckl (Solution Architect at 
LIS-Linuxland GmbH) [Thu-Fri], Michal Skrivanek (oVirt developer at Red 
Hat) [Fri], Denise Stöckl (Junior Account Manager at LIS-Linuxland GmbH) 
[Thu-Sat] and me [Thu-Sat].


From Thursday till Saturday we had the oVirt stand with a Live 
Demo-System and had some interesting talks with conference participants. 
Many of the guys who came to the stand where really surprised how many 
features oVirt offers compared to their standalone virt-manager setups. 
The highlights where live migration and cloud-init for them. Admins of 
bigger companies saw a real alternative to their VMware setups in oVirt



On May, 8th my talk about new features in oVirt took place. It was 
basically the same talk as in Graz. Here you can find the slides:

https://cfp.linuxwochen.at/system/attachments/68/original/Neue_Features_der_Open_Source_Virtualisierungsl%C3%B6sung_oVirt.pdf?1399879368


The 50 listeners of the talk asked a lot of questions and the feedback 
was that oVirt looks like a good alternative to VMware.



On April, 9th I had the oVirt installation workshop, which was the same 
as in Graz with the exception that I didn't made it interactive, but 
showed all the steps on 3 notebooks of mine. This was due not enough 
live sticks and missing infrastructure (no pcs in the workshop room). 15 
participants made it easy for everyone to ask detailed questions to all 
the steps we did.


Also for the workshop in Vienna I have German slides available:

* 
https://cfp.linuxwochen.at/system/attachments/69/original/oVirt_Workshop.pdf?1399879392



Feedback from users was really good and the top questions for features 
were also:

- Support for Linux container (lxc)
- Support for Debian (engine and hosts).


Here are also some pictures of the Linuxwochen Vienna event stand (we 
don't have pictures with participants or pictures of talk/workshop yet):

Last but not least I want to thank Brian, Dave, Michal and Frantisek 
from oVirt team and Peter and Denise from LIS-Linuxland for supporting 
me bringing oVirt to these 2 events.

René

I was looking on launchpad but onli 13.x latest

We currently do not have version specific builds. I hope that this will
be changed in future.
But it'd be great if you try if 13.x works for you.


13.10 is working fine for 14.04...

[ovirt-users] REST-API connection limit / SSL read timeout? (was: Failure to connect to engine with Nagios)

[René Koch]

Hi list,

I use Perl (LWP::UserAgent, HTTP:::Request) to connect to oVirt REST-API 
and fetch data with my Nagios plugin. 2 users complained now that my 
plugin stops working for their monitoring user (IPA backend).


It worked fine with their monitoring@ipa user a few weeks and suddenly 
it stopped working. If using another user (another IPA user or 
admin@internal) it's fine.


Here's the response from oVirt engine (JBoss) for this user:

* Header:
Content-Type: text/plain
Client-Date: Mon, 21 Apr 2014 14:19:31 GMT
Client-Warning: Internal response

* Content (the default timeout is 15 seconds):
500 SSL read timeout:

User permissions are fine, btw.

Does anyone know if there's a connection limit to REST-API on a user 
base? Or can anyone give me a hint how to troubleshoot this issue (I 
can't reproduce this behavior in my environment btw).



Thanks a lot,
René

We are having some trouble with the Nagios plugin for oVirt. From time

Once vdsm is happy hosted engine VM will start.


Thanks for your feedback, Doron.

My ovirtmgmt bridge seems to be on or isn't it:

I tried the following yesterday:
Copy virtual disk from GlusterFS storage to local disk of host and 
create a new vm with virt-manager which loads ovirtmgmt disk. I could 
reach my engine over the ovirtmgmt bridge (so bridge must be working).


I also started libvirtd with Option -v and I saw the following in 
libvirtd.log when trying to start ovirt engine:
2014-04-22 14:18:25.432+: 8901: debug : virCommandRunAsync:2250 :

So it could be that something is broken in my hosted-engine network. Do 
you have any clue how I can troubleshoot this?

Hi,

I rebooted one of my ovirt hosts today and the result is now that I

ovirt-ha-agent isn't running because the lockspace file is missing

The errors seem to indicate that you somehow lost the lockspace file.


True :)
Isn't this file created when hosted engine is started? Or how can I 
create this file manually?

No space left on device is nonsense as there is enough space (I had this

Any idea what prevents hosted-engine from starting?
ovirt-ha-broker, vdsmd and sanlock are running btw.

Btw, I can see in log that json rpc server module is missing - which 
package is required for CentOS 6.5?
Apr 22 12:37:14 ovirt-host02 vdsm vds WARNING Unable to load the json 
rpc server module. Please make sure it is installed.

Hi,


How can I disable notifications?


The notification is configured in /etc/ovirt-hosted-engine-ha/broker.conf 
section notification.
The email is sent when the key state_transition exists and the string 
OldState-NewState contains the (case insensitive) regexp from the value.


Is it intended to send out these messages and detect that ovirt engine
is down (which is false anyway), but not to restart the vm?


Forget about emails for now and check the 
/var/log/ovirt-hosted-engine-ha/agent.log and broker.log (and attach them as 
well btw).


oVirt hosts think that hosted engine is down because it seems that hosts
can't write to hosted-engine.lockspace due to glusterfs issues (or at
least I think so).


The hosts think so or can't really write there? The lockspace is managed by 
sanlock and our HA daemons do not touch it at all. We only ask sanlock to get 
make sure we have unique server id.


Is is possible or planned to make the whole ha feature optional?


Well the system won't perform any automatic actions if you put the hosted 
engine to global maintenance and only start/stop/migrate the VM manually.
I would discourage you from stopping agent/broker, because the engine itself 
has some logic based on the reporting.

oVirt engine is sending me 2 emails every 10 minutes with the following
subjects:
- ovirt-hosted-engine state transition EngineDown-EngineStart
- ovirt-hosted-engine state transition EngineStart-EngineUp

In oVirt webadmin I can see the following message:
VM HostedEngine is down. Exit message: internal error Failed to acquire
lock: error -243.

These messages are really annoying as oVirt isn't doing anything with
hosted engine - I have an uptime of 9 days in my engine vm.

So my questions are now:
Is it intended to send out these messages and detect that ovirt engine
is down (which is false anyway), but not to restart the vm?

How can I disable notifications? I'm planning to write a Nagios plugin
which parses the output of hosted-engine --vm-status and only Nagios
should notify me, not hosted-engine script.

Is is possible or planned to make the whole ha feature optional? I
really really really hate cluster software as it causes more troubles
then standalone machines and in my case the hosted-engine ha feature
really causes troubles (and I didn't had a hardware or network outage
yet only issues with hosted-engine ha agent). I don't need any ha
feature for hosted engine. I just want to run engine virtualized on
oVirt and if engine vm fails (e.g. because of issues with a host) I'll
restart it on another node.

Thanks,
René




I'm pretty sure we removed hosted-engine on gluster due to concerns
around the locking issues.
is the gluster configured with quorum to avoid split brains?



At the moment there's no quorum (1 host online is enough - but GlusterFS 
network is on dedicated nics which are directly connected between two 
hosts), as I'm waiting for additional memory and disks for the other 2 
nodes (so I have only 2 nodes atm).


But GlusterFS looks fine (now) - same for info heal-failed and info 
split-brain:


# gluster volume heal engine info
Gathering Heal info on volume engine has been successful

Brick ovirt-host01-gluster:/data/engine
Number of entries: 0

Brick ovirt-host02-gluster:/data/engine
Number of entries: 0


I can also create (touch) the lockspace file on the mounted GlusterFS 
volume - so imho GlusterFS isn't blocking libvirt.

- yes, it might cause some problems if you set up another host for

[ovirt-users] hosted engine health check issues

timeout=Mon Apr 14 10:35:05 2014

oVirt engine is sending me 2 emails every 10 minutes with the following 
subjects:

- ovirt-hosted-engine state transition EngineDown-EngineStart
- ovirt-hosted-engine state transition EngineStart-EngineUp

In oVirt webadmin I can see the following message:
VM HostedEngine is down. Exit message: internal error Failed to acquire 
lock: error -243.


These messages are really annoying as oVirt isn't doing anything with 
hosted engine - I have an uptime of 9 days in my engine vm.


So my questions are now:
Is it intended to send out these messages and detect that ovirt engine 
is down (which is false anyway), but not to restart the vm?


How can I disable notifications? I'm planning to write a Nagios plugin 
which parses the output of hosted-engine --vm-status and only Nagios 
should notify me, not hosted-engine script.


Is is possible or planned to make the whole ha feature optional? I 
really really really hate cluster software as it causes more troubles 
then standalone machines and in my case the hosted-engine ha feature 
really causes troubles (and I didn't had a hardware or network outage 
yet only issues with hosted-engine ha agent). I don't need any ha 
feature for hosted engine. I just want to run engine virtualized on 
oVirt and if engine vm fails (e.g. because of issues with a host) I'll 
restart it on another node.


Thanks,
René

RHEL 6.5 host hasn't the bits needed to support multi-monitor with the

[ovirt-users] VM samba4 is down. Exit message: 'int' object has no attribute 'replace'.

[René Koch]

Hi,

I configured Network QoS in my oVirt 3.4 setup, but can't start vms.

Here are the steps I did:
- Create QoS in Data Centers - Network QoS tab (Name: testing, limits: 
10/10/100, 10/10/100)

- Add QoS to vNIC Profile using Networks - vNIC Profile - edit

When I try to start a vm the following error is shown in vdsm.log:

When removing the QoS (or better say put it to unlimited) my vm is 
starting fine.


My host is running CentOS 6.5 with latest updates.

Re: [ovirt-users] [Users] hosted engine setup (NFS)

Hi,

I installed hosted engine and faced an issue with NFS during installation.

First of all, I'm using GlusterFS on my storage and ovirt engine doesn't 
support GlusterFS yet, only NFS.

But for NFS I can't use mountprotpo=tcp as hosted-engine --setup doesn't ask 
for NFS options.

So I manually edited the following file:
/usr/share/ovirt-hosted-engine-setup/plugins/ovirt-hosted-engine-setup/storage/storage.py

and changed opts.append('vers=3'):

 if domain_type == 'nfs3':
 fstype = 'nfs'
 opts.append('vers=3,mountproto=tcp')

My question is now: is it possible to ask for NFS options during setup or do 
you think this can lead into problems? NFS via TCP worked fine for me for
one week until I rebooted the host today (did reboot tests last weeks, too 
which was fine) and can't start hosted engine anymore (see other mail
thread), but I think the other issue is not NFS mountproto related.




Well, in hosted-engine setup we don't ask for additional options because we 
don't store them.
We just ask for nfs3 or nfs4 because we pass that value as protocol version to 
VDSM connectStorageServer verb.
The above change affects only the temporary mount done for validating the 
domain.


Thanks a lot for the information.

Btw, I can mount mit GlusterFS 3.4.2 NFS share now without specifying -o 
mountproto=tcp. Is upd now possible or is the protocol determined 
automatically now? I didn't test if hosted-engine-setup is able to mount 
GlusterFS NFS shares now without hacks, too - only discovered this new 
behavior on my hosts.


Slightly off-topic question:
The storage options are stored in 
/etc/ovirt-hosted-engine/hosted-engine.conf, right? If I want to change 
the ip address of my storage I simply put engine into global maintenance 
mode, change IP in hosted-engine.conf and re-enable hsoted-engine vm 
again? Or are there more steps required?

René

Re: [ovirt-users] minimum DNS requirements for /etc/hosts

So like the nut job I am, I host my dns server on a virtual machine
that is now hosted by ovirt, I also have a few gateway machine in
there as well for routing traffic between internal networks.  With
virt-manager, DNS rarely seemed to be an issue. I'd connect to a host
IP, and bring up the vm, no problem. Ovirt on the other hand takes
forever if dns is down. So i've passed around a /etc/hosts file to
resolve any ip address that ovirt might be looking for while dns is
out.  I'd like to verify at an abstract level, what needs to be in
said file, to keep everything from timing out, or just taking forever.

name and FQDN of each host
name and FQDN of engine host
name and FQDN of each storage domain.

Is this enough, or are there other places/things the ovirt node and
hosts might be trying to resolve?


Afaik this should be enough.
Just remember that e.g. ssh login will still be slow if the DNS server 
isn't reachable as you have to wait until it reaches a timeout.


My oVirt setup doesn't have any DNS entry - just the hosts and engine in 
/etc/hosts. But I don't use DNS names at all only IP addresses...

(http://ppa.launchpad.net/zhshzhou/vdsm-ubuntu/ubuntu/pool/main/o/ovirt-guest-agent/ovirt-guest-agent_1.0.9.20140216.git5168c4-1ppa1_all.deb)
, since I'm not willing to add ubuntu sources to my apt-configuration
since that might make me run into dependency troubles later on.


This one works fine with Debian:

https://launchpad.net/~zhshzhou/+archive/vdsm-ubuntu/+files/ovirt-guest-agent_1.0.8.201309301944.gitb7f8f2-1ppa1_all.deb

The version you try to use is for Ubuntu 13.10.


Regards,
René




After downloading and dpkg -i'ing it, I ran an apt-get -f install in
order to get the dependencies. Then I reran dpkg:


root@host:~# dpkg -i
ovirt-guest-agent_1.0.9.20140216.git5168c4-1ppa1_all.deb

Errors were encountered while processing:
   ovirt-guest-agent_1.0.9.20140216.git5168c4-1ppa1_all.deb

There's a configfile regarding initscripts in /etc/init,  but no such
thing on the sste, (I just had a look at the contents of the ubuntu
package too).
How did you resolve this? Creating my own initscript isn't that hard but
it sucks when it comes to having a maintainable setup...

René,
do you have a list of distro's / agent you work with?


I have the following guests:
RHEL 6  - guest agent from EPEL
CentOS 6- guest agent from EPEL
RHEL 5  - guest agent from RHEL repositories
Fedora 20   - guest agent from Fedora repository
Solaris 10  - no guest agent
Solaris 11  - no guest agent
Ubuntu 12.04- guest agent from launchpad
Debian 7- guest agent from launchpad (Ubuntu Precise)

I don't have openSUSE running on my new setup anymore, but guest agent 
from build.opensuse.org did work fine. SLES 11 didn't work.



Regards,
René



We may want to update the wiki with the list you have.

Thanks,
Doron

[Users] 2 virtual monitors for Fedora guest

[René Koch]

Hi,

I'm trying to virtualize my Fedora 20 workstation on oVirt 3.4 with 2 
screens.


No matter if I choose Server or Desktop and operating system Linux or 
RHEL 6.x x64 (surprisingly Fedora is missing in the list) my Fedora 
guest (or better say LXRandR) only recognizes 1 monitor.


ps -ef | grep myvm shows me that there are 2 monitors (or at least I 
think that I can interpret the output this way):
-vga qxl -global qxl-vga.ram_size=134217728 -global 
qxl-vga.vram_size=33554432


Does anyone know how I can make my Fedora guest work with 2 screens?
Thanks!

Probably you already visited this:
http://www.ovirt.org/Features/SPICERelatedFeatures#Multi_Monitor_support_for_Linux_guests_.28Basic.29


No, I didn't - thanks a lot for the link.
As it says it's for oVirt 3.1 it properly should be in oVirt 3.4.



but from the text is not so clear to me if it is completely doable or
not in 3.4 ...
The page refers to Xinerama in need to be configured inside the guest
I don't know if for QXL device and fedora 20 one has to trick with
xorg.conf or not putting something like


Hurra - we're in year 2014 and Linux is still not able to configure 2 
screens with a simple click. :(


Btw, I don't even find a config file for ServerLayout section in /etc/X11.



Section ServerLayout
 Identifier   Layout0
 InputDevice  Keyboard0 CoreKeyboard
 InputDevice  Mouse0CorePointer
 Option   Clone off
 Option   Xinerama  on
 Screen   0   Screen0
 Screen   1   Screen1 Below Screen0
EndSection

Does your Xorg.0.log gives any useful information regarding the two
devices and anythng about Xinerama?


In Xorg.0.log I can see the following:
qxl(0): Output Virtual-0 has no monitor section
qxl(0): Output Virtual-1 has no monitor section
qxl(0): Output Virtual-2 has no monitor section
qxl(0): Output Virtual-3 has no monitor section
snip
qxl(0): Output Virtual-0 connected
qxl(0): Output Virtual-1 disconnected
qxl(0): Output Virtual-2 disconnected
qxl(0): Output Virtual-3 disconnected

Whatever this mean. No clue about Xorg - should install X on my servers 
to get more practice in it :)


Btw,
in Remote Viewer I can choosee View - Display and select Display 2.
In second remote viewer windows I see Waiting for display 2... - os it 
seems that at least the port is for second display is open on my host.


So I guess oVirt is working fine and the question about the dual screen 
mode can be answered best on Spice or Fedora mailing list?

No configuration nor Xinerama should be needed. Just make sure you have
spice-vdagent package installed, spice-vdagentd service running and two
spice-vdagent processes running (one for *dm, one for your user

No Xinerama sounds great!

vdagent was already installed and is running:

Xinerama is an old hackish means to multimonitor for linux guests with
numerou disadvantages so please avoid that. If you really really want to
use xinerama, then switch your OS type to Windows and your VM will get
multiple qxl devices that xinerama depends on.


I don't want to use it and hack in Xorg config files :)

You can assign quotas per user. Quotas are disabled per default, so you 
have to enabled it for your datacenter.


I also suggest to assign permissions for your users to self provisioning

portal users can always see all vms.

Can I change the qemu xml somewhere?


can you please explain the use case?


We have software developers who need VMs to test their software and for
some test a display of 1280x1024 is necessary. The default cirrus
graphics card is not good enough for that.

But we have some VMs which use a Red Hat Virtual graphics adapter and we
don't know how this happened or how it is configured.

We just figured out that the difference may be connecting with SPICE or VNC.

Is there a different way to change the grapics card permanently?


You just have to install the QXL drivers in your vm and connect via 
SPICE. I didn't test it in oVirt but in RHEV there's no need to change 
the graphics adapter, just install the QXL drivers, as guests fall back 
from QXL graphics card to standard VGA graphics card if the driver is 
missing.


You can find the QXL drivers here: http://www.spice-space.org/download.html

oVirt uses both - JBoss and Apache. You should place your PHP file in 
html dir of Apache, not JBoss.




if i want to run a PHP file, where should i save it?


Just save it to /var/www/html, which is the default location for your 
Apache webserver and install PHP module.


You should be able to browse to http://ovirt/myfile.php. If not, you 
exclude the path in Apache vhost configuration file ovirt-engine.conf:

ProxyPass /myfile.php !

Hope this helps,

Not pxe boot the vm, but boot a thin client to make use of a vm
running on
oVirt. Is that possible?


I have never tried, but I guess making a minimal linux image booting
the thin client
to the browser, which should be pointing to the user portal login
page should be
good.



I know that downstream, with RHEV, we've got customers doing this - where Red 
Hat services helped build a kiosk image of RHEL for this purpose.

A number of thin client vendors do support spice.


We also have some customers using VDI with RHEV. We normally use thin 
clients from IGEL (https://www.igel.com), but any thin client should be 
possible if it has a web browser with SPICE plugin (best running Firefox 
in Kiosk mode with oVirt user portal as landing page).

Rene

Does anyone have instructions on how to pxe boot a an ovirt
hosted vm?


As long as the VM's vNIC is on a VM network that has access to the
pxe server
it should just work (it does for me).

I'm not sure if this will work if you have a tagged and untagged logical 
network.




Shouldnt vm assigned to the Blue network be able to communicate to my
firewall which has the interface tagged as vlan 2 and an IP address of
172.17.0.1?


Your vm should be able to communicate with your firewall if you did 
configure network correctly:

- configure VLAN on firewall interface
- configure VLAN on oVirt hosts (done by oVirt automatically)
- set switch ports to tagged for VLAN 2

As said I'm not sure if your mix of migration and blue network will 
work. In my environment my (cheap) switches can't deal with a port where 
tagged and untagged traffic is sent.

I have tested an upgrade from engine 3.3.3 to 3.3.4 under centos 6. It

- install vdsm-gluster
- start glusterd service


Did you check Enable Gluster Service for your cluster? If so, you need 
vdsm-gluster installed on all hosts. If you don't use GlusterFS on your 
hosts, disable this setting for your cluster.

We are only currently using ISCSI. I cannot get a node running
vdsm-4.13.3-3 to show as being operational under engine 3.3.4

Has anyone been able to get 3.3.4 functioning with previous version vdsm
nodes ?

This issue may hinder our progress when it comes time to upgrade our
production engine / nodes when putting hosts into maintenance mode and
performing migrations etc.

Re: [Users] [RFI] GUI Changes for oVirt 4.0

Dňa 18.03.2014 11:29, Itamar Heim wrote / napísal(a):

Hi,

we are brainstorming on what should we change in the oVirt UI for 4.0.
for current brainstorming phase, anything goes - i.e., I'd like us
to ignore current limitations and flows, and envision/fantasize the
perfect solution.


Anything goes is great - so here's what came in mind :)

I would love to be able to use drag and drop in the gui. E.g. Drag and 
drop an vm selected in Virtual Machines tab to an host in the left 
system navigation menu. Or drag and drop it on Templates tab and the New 
Template window appears.


It would be cool if help would be available. When I installed oVirt 3.4 
I discovered a subtab Affinity Groups for my vms and I had no clue 
what I could do with this feature. So I visited oVirt wiki and searched 
for Affinity Groups and now I know what this is all about. But if a 
small ? button would be available in the right upper corner of this 
tab explaining this feature in 1-2 sentences and giving a link to a 
detailed documentation page would help for non-experienced users/admins 
(online in oVirt wiki or offline shipped with oVirt).


Furthermore I would love to be able to use ui plugins for User portal as 
well...


What about a tab Logs where I could access engine.log file? At the 
moment I have to switch to console to be able to get more detailed 
information about an error and use search bar to find the corresponding 
line.




SO - what do YOU think we should consider for 4.0 UI concept, flows, etc.


I'd love to see this in the UI:

- auto-refreshed screenshots from the VMs consoles.
- some improved tagging/grouping


What about adding the possibility to create a tab out of a bookmark? I'm 
thinking of the following: Add a bookmark which displays all VMs 
belonging to Datacenter A and a bookmark which displays all VMs 
belonging to Datacenter B. So for me it would be cool if I would have a 
new main tab VMs in DC A and VMs in DC B - so I don't have to switch 
from System menu to Bookmarks menu, but can customize main tabs to best 
fit into my environment.



- customizable columns with sorting/filtering (tags ?)


This would be cool.
I would love to be able to sort or enable/disable certain columns. E.g. 
FQDN column is pretty useless for me as the vm name already contains the 
FQDN in my setup. It would be cool if it would be possible for each user 
to create his view and have this saved.



- cpu/disk/net utilization column like virt-manger has them


It would be great if I could add columns using ui plugins.
So e.g. I remove FQDN, Display, Status columns, but add my custom one 
with the monitoring status or I can add my custom graphs based on my 
monitoring system (or whatever) in addition or instead of the defined 
CPU/Memory/Network columns...



- embedded serial console
- disk operations and migration status with progress bar and ETA.


Vote for this as well.


- console access from client-engine-host. Most of the time we do not
have direct access to the hosts.
- ability to define exclude entities ( aka these 2 vms may never run on
the same storage and host )

Hello,

Is it possible to install Solaris 11 in Ovirt?. If yes please guide me.


Yes, it is possible with a hook script which removes the CPU model from

on AMD CPUs, only on Intel.


Download 99_fix_solaris from:
https://github.com/ovido/ovirt-stuff/tree/master/hooks
and follow the instructions on this page on how to install it / prepare 
your vm.


Btw, does it make sense to add my hook (packaged as RPM) to oVirt 
repository as there are some requests for it on this mailing list?

The host moving to Non-Operational state with error Gluster command
failed... is dependent on whether Enable gluster service is checked
on your cluster. This check indicates that you also want to manage
gluster storage provisioning on the nodes.

A recent change now checks that vdsm-gluster support is available for
such clusters. That's probably why you are seeing this error after update.



Thanks, now it's clear.
I indeed have enabled Gluster service in my cluster (but I don't use it 
as I did configure the volumes with gluster command directly)

vdsm-gluster is to manage gluster storage, not consume gluster storage.
did you enable the gluster mode post installing the hosts?
(if you enabled it before installing them, or re-install[1] post
enabling gluster mode, it should have deployed vdsm-gluster as well)

[1] after moving hos to maintenance.


Yes, I did it after installing the hosts.

Would it be possible to add a check before activating this option?

I'm thinking of the following:
- Edit Cluster
- Enable Gluster Service
- OK checks if all hosts in the cluster have vdsm-gluster installed - if 
not an error message occurs that this package is required in order to 
enable the gluster service.

According to yum.log vdsm-gluster was never installed on these hosts,
but storage did work.

Shouldn't vdsm-gluster be a requirement for hosts and therefor be
installed during host setup?

Do you have any clue why it storage did work until the update of these
packages?


vdsm-gluster is to manage gluster storage, not consume gluster storage.
did you enable the gluster mode post installing the hosts?
(if you enabled it before installing them, or re-install[1] post
enabling gluster mode, it should have deployed vdsm-gluster as well)

[1] after moving hos to maintenance.


Yes, I did it after installing the hosts.

Would it be possible to add a check before activating this option?

I'm thinking of the following:
- Edit Cluster
- Enable Gluster Service
- OK checks if all hosts in the cluster have vdsm-gluster installed - if
not an error message occurs that this package is required in order to
enable the gluster service.


makes sense - please open a bug to track. check would probably warn if
unreachable hosts exists to warn user.

[Users] hosted engine issues

[René Koch]

Hi,

I have some issues with hosted engine (oVirt 3.4 prerelease repo on 
CentOS 6.5).

My setups is the following:
2 hosts (will be 4 in the future) with 4 GlusterFS shares:
- engine (for hosted engine)
- iso (for ISO domain)
- ovirt (oVirt storage domain)

I had a split-brain situation today (after rebooting both nodes) on 
hosted-engine.lockspace file on engine GlusterFS volume which I resolved.


hosted engine used engine share via NFS (TCP) as glusterfs isn't 
supported for oVirt hosted engine, yet. I'll switch to GlusterFS as soon 
as oVirt will support it (I hope this will be soon as RHEV 3.3 is 
already supporting GlusterFS for hosted engine).



First of all ovirt-ha-agent fails to start on both nodes:

How did you solved it? By switching to NFS only?



I removed the file on host1 (directly on the brick) and ran gluster 
volume heal engine full, which synced the file from host2 to host1.

seems like a vdsm failure in starting monitor the hosted engine storage domain.
Can you attach vdsm logs?


Logs are quite big for an email (6.8MB).
I attached the last entries which show the information for vm-start.

Re: [Users] Proper way to reboot an ovirt node

[René Koch]

On 03/03/2014 11:14 AM, Jonas Israelsson wrote:

What is the recommended proper way reboot an Ovirt node ?

I started by putting the host into in Maintenance mode and was going to
via the TUI interface just reboot the machine.
Should I then use the confirm host rebooted before I put the host back
from Maintenance mode ?


No, you don't need to use confirm host rebooted. This option is only 
required if you solved an issue manually.


Maintenance - reboot and activate is the right way.

René




I have rebooted my Nodes violently hundreds of times (and they have
always recovered), but now I have data/config that I'm keen not to loose.

Failed to find this info on the wiki...

[Users] hosted engine setup (NFS)

[René Koch]

Hi,

I installed hosted engine and faced an issue with NFS during installation.

First of all, I'm using GlusterFS on my storage and ovirt engine doesn't 
support GlusterFS yet, only NFS.


But for NFS I can't use mountprotpo=tcp as hosted-engine --setup doesn't 
ask for NFS options.


So I manually edited the following file:
/usr/share/ovirt-hosted-engine-setup/plugins/ovirt-hosted-engine-setup/storage/storage.py

and changed opts.append('vers=3'):

if domain_type == 'nfs3':
fstype = 'nfs'
opts.append('vers=3,mountproto=tcp')

My question is now: is it possible to ask for NFS options during setup 
or do you think this can lead into problems? NFS via TCP worked fine for 
me for one week until I rebooted the host today (did reboot tests last 
weeks, too which was fine) and can't start hosted engine anymore (see 
other mail thread), but I think the other issue is not NFS mountproto 
related.

[Users] hosted engine setup (network)

[René Koch]

Hi,

During hosted engine setup I faced issues with network configuration on 
my CentOS 6.5 hosts:


My network setup was the following which doesn't work with hosted engine 
setup:

- eth0.200 (VLAN tag 200) should become ovirtmgmt interface
- GATEWAY is in /etc/sysconfig/network and not in ifcfg-eth0.200

The following errors occured:
014-02-25 15:42:31 INFO 
otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189

line 231, in _misc

'gateway=%s' % caps['cfg']['GATEWAY'],
KeyError: 'GATEWAY'

This can be solved by setting GATEWAY in ifcfg-eth* file instead of 
/etc/sysconfig/network



Next, VLAN tagged interfaces don't work:
2014-02-25 15:35:20 INFO 
otopi.plugins.ovirt_hosted_engine_setup.network.bridge bridge._misc:189

line 194, in _misc

].s.getVdsCapabilities()['info']['nics'][nics]
KeyError: 'eth0.200'

So I had to do the following:
- Set switch port to untagged for this VLAN
- Configure eth0 instead of eth0.200
- Run hosted engine setup
- Configure VLAN for ovirtmgmt in oVirt (which surprisingly worked for 
an active interface)

- Configure VLAN tagging on hosts
- Reconfigure switch ports
- Sync networks in oVirt network setup tab

As this was a real pain to do I would love to see support for VLAN 
tagging in hosted engine setup :)



Shall I open bug reports for these 2 issues or are they already known?

Hi,

On 02/24/2014 05:59 PM, Itamar Heim wrote:

with oVirt 3.4 getting close to GA with many many great features, time
to collect requests for 3.5...



Here's my wish list :)

- Cloning of vms VMs without templates (of is this already implemented)?

- Enable host updates through engine (yum update via oVirt engine)

- Integrate v2v into oVirt engine

- hosted engine with iSCSI/FC/GlusterFS support

- ISO and export domain on FC/iSCSI/GlusterFS would be nice
ISO domain on GlusterFS using POSIXFS domain doesn't work for me in 
oVirt 3.4


- Central Repository for oVirt guest agents
Atm packages are available for Debian, SLES, RHEL/CentOS, Fedora but 
there are different sources and users have to know where to find the 
guest tools. So would love to see e.g. 
http://resources.ovirt.org/guest-agents/{ubuntu,debian,opensuse,...}


Windows needs to be created manually as described here 
http://www.ovirt.org/OVirt_Guest_Agent_For_Windows, right?


I could provide repositories for guest agent in a central point and also 
Windows guest agent packages if you don't plan to do it on ovirt.org as 
I have to required infrastructure (OBS with multiple distributions in 
it) on our side.


- RHEV guest tools APT (Application Provisioning Tool) for Windows 
ported to oVirt

This makes it easier to update guest tools on Windows...

- Upload ISOs thorugh oVirt engine gui

- Use existing share for ISO domain
When creating an ISO domain, oVirt creates it's own directory structure 
with IDs. It would be nice if an existing share could be used (e.g. an 
ISO share on NFS server which is used by other service, too) without 
creating the structure with IDs. I know that the IDs are needed 
internally but I think it should be possible to reuse an existing share.


- Signed RPMs
gpgcheck=0 is really ugly...

- NFS options for storage domains
It would be great if I can change NFS options like e.g. mountproto=tcp 
for NFS storage domains.

René
