+1.
We are going to disable it entirely in coming version.

Hi Pavel,

   Thanks, I added the 3.6-snapshot repo to upgrade to vdsm 4.17.36 and
then diagnosed a bunch of LVM problems (PV's set as missing in pvs -v)
and that got us fixed back up!

I'd not say "really not an option", but no-one I know ever tested this
or intended to support this. To get a feeling of what you are getting
into, you can check the git log from 4.0.4 to 4.0.5 for the directory
packaging/dbscripts. Looking at it, you can see e.g. [1]. This means
that on upgrade to 4.0.5, engine-setup ran this code for you. It also
remembers it did (that's saved in the db too). So if in 4.0.4 with a
4.0.5 db you then do some changes that this code should have affected,
it will not run again against your changes when you eventually do upgrade.

To see the git log, you can do something like this:

git clone https://gerrit.ovirt.org/p/ovirt-engine.git
cd ovirt-engine
git log -u $(git merge-base ovirt-engine-4.0.4.4
ovirt-engine-4.0.5.5)..ovirt-engine-4.0.5.5 packaging/dbscripts

Best,

Re: [ovirt-users] Import guest at rhv4.0.6 failed after convert a regular ova file by virt-v2v

[Shahar Havivi]

Yevgeny, please look why it fails on "isMacInRange"

Kun, you know that you can import ova directly instead of using virt-v2v to
export domain and then import to data domain,
you can do that from the VMs tab->Import-> and change the source to OVA.

Re: [ovirt-users] Storage Problem After Host Update (v3.6)

[Pavel Gashev]

Charles,

Please note the warning in logs about lvmetad. It's better to disable this 
service if you invoke LVM utilitities manually. It caches some LVM metadata but 
VDSM doesn't use it. So technically VDSM has different view on PVs.

Please check also BRANDING.adoc from the engine source tree [1].
You should be able to add your own directory wherever you want and link
to it from /etc/ovirt-engine/branding with a higher number, and it will
override the default. You can try either copying only what you want or
all of the existing directory.

[ovirt-users] [Ansible - Ovirt] How to specifiy ovs properties ?

[TranceWorldLogic .]

Hi,

I want to setup a logcal ovs network in ovirt.
And to do the same I want to use ansible tool.

Hence I tried looking into ansible document and found below link.
https://docs.ansible.com/ansible/ovirt_networks_module.html

But question is how to configure propert "ovs = 1" in ansible.
It may be via nested_attributes but not sure how to do so.
Please let me know.

Thanks,
~Rohit

Re: [ovirt-users] Storage Problem After Host Update (v3.6)

[Charles Tassell]

Hi Pavel,

  Thanks, I added the 3.6-snapshot repo to upgrade to vdsm 4.17.36 and 
then diagnosed a bunch of LVM problems (PV's set as missing in pvs -v) 
and that got us fixed back up!

Hello,

One of our admins did a package update on one of our 3.6 hosts
through the web GUI and then rebooted the host.  Since then, it hasn't
been able to properly mount storage and thus we can't move any VMs to
it.  I rebooted it myself this afternoon and it took our whole cluster
down for about a half hour, which was kind of concerning.

We use multipath fibre channel for storage and when I do a vgscan or

constantly repeating in vdsm.log.  Any ideas what's going on and how I
fix it?

In oVirt 4.1 we are planning to allow VM leases that will allow you to restart 
HA VMs in this use case even without power management.
We would love some feedback on this on the latest tested build, if you want to 
try it out:

Hi,

high availability requires power management to be configured properly for your 
hosts. The VM won't be restarted until we can ascertain the status of node2 
(because it can still be up).

The host is Non responsive, meaning we do not know if it is up or down. That is 
the reason we show the VM status as unknown.

You can fix that by configuring power management for node2 or by right clicking 
and selecting Confirm host has been rebooted menu option.

Did I understand ha correctly? Anyon can help? Thanks!

That would still mean that I have to type in my login credential twice,
which is what I'm trying to avoid.

So in step 4, can't it just start a new session instead of going to an
expiration page? Or show the page for a few seconds and then start a new
session? 

Or in step 2, set a refresh on the login page that still has a session so
that when the session expires it will redirect to a login screen that will

Re: [ovirt-users] 4.0 web UI Session expired please try again

[Ravi Nori]

With SSO the client sends the client secret to SSO which is stored in the
session. Now when the clients session expires all the information including
the client secret is lost when the session is purged by the application
server.

Here is the sequence

1. login to webadmin
2. Leave the session until session time out on engine and user is
redirected to login page (the client id and secret are sent)
3. If user tries to login now everything will be fine but if user leaves
and the session expires the session is purged, client secret is lost
4. User enters user name password on the screen after coming back. The
login form does not have a session associated with it so the client and
secret are not found and SSO needs to report that the session has expired
and redirect user to welcome page.

The client id and secret cannot be stored in login page as they are
supposed to be kept secret.

To revert to old behavior we need a patch that can save  client and secret
for the session out side the session object in a global data structure
and create a unique token that can be used to associate the login page with
the client secret stored in the global data structure.
The token can be included in the login page.

Re: [ovirt-users] PLEASE HELP - oVirt 4.0.5 Instability + Best way to rollback to 4.0.4

[Rogério Ceni Coelho]

Oh my god ... This option means a lot of work ... But thanks anyway ... I
think in this case are more easy to clone this six new VMs (that does not
exist on ovirt engine database 4.0.4) to another Storage Domain with NFS or
oVirt Production enviroment and recreate them after checkpoint rollback.

Do you think ovirt-engine database restore are really not an option from
4.0.5 to 4.0.4 ?

Thanks.

Re: [ovirt-users] Optimizations for VoIP VM

Once upon a time, Yaniv Dary  said:

For VoIP, latency can be an issue, but the amount of latency from adding
VM networking overhead isn't a big deal (because other network latency
will have a larger impact).  10ms isn't really a problem for VoIP for
example.

The bigger network concern for VoIP is jitter; for that, the only
solution is to not over-provision hardware CPUs or total network
bandwidth.

[ovirt-users] 4.0 web UI Session expired please try again

[Robert Story]

Since I upgrade to 4.0, I get this annoying message when I try to log in
again after I've been away for a while. On 3.6 the ui would go to a login
screen after some period of inactivity, and I could log right back in. With
4.0, logging in after inactivity goes to a page with this message, and I
have to click to get a login page and then log in again. This is very
annoying. Is there a way to revert to the old behavior?

In the SDK the services are arranged in a tree structure that mimics the
URL structure of the API. For example, if you want to get the service
that manages a particular snapshot, in the API you would use an URL like
this:

  /ovirt-engine/api/vms/123/snapshots/456

In the Python SDK that translates into this:

  snap_service = connection.system_service() \
.vms_service() \
.vm_service('123') \
.snapshots_service() \
.snapshot_service('456')

There is also a generic "service" method that is useful when you already
have all that path as an string:

  snap_service = connection.service("vms/123/snapshots/456")

Both return exactly the same object. The first is usually better when
you are calculating the path of the object step by step, and I generally
prefer it as it is less error prone.

Once you have the reference to the service, you can use the 'remove' method:

  snap_service.remove()

If you need to search by the names of the objects, then you can use the
'search' methods, which are only available for the top level objects,
like VM, data centers, clusters, etc. For example, to find your virtual
machine and then the snapshot:

  # Get the root service:
  system_service = connection.system_service()

  # Find the virtual machine:
  vms_service = system_service.vms_service()
  vm = vms_service.list(search='name=myvm')[0]

  # Find the snapshot:
  vm_service = vms_service.vm_service(vm.id)
  snaps_service = vm_service.snapshots_service()
  snaps = snaps_service.list()
  snap = [s for s in snaps where s.description == 'My snap'][0]

  # Remove the snapshot:
  snap_service = snaps_service.snap_service(snap.id)
  snap_service.remove()

Re: [ovirt-users] PLEASE HELP - oVirt 4.0.5 Instability + Best way to rollback to 4.0.4

Hello oVirt Padawan,
You can install new engine machine and import existing storage domains
there.
https://www.ovirt.org/develop/release-management/features/storage/importstoragedomain/
Please read restrictions and limitations.
I think it's more safe way to go in such kind of situations.

[ovirt-users] PLEASE HELP - oVirt 4.0.5 Instability + Best way to rollback to 4.0.4

[Rogério Ceni Coelho]

Hi oVirt ObiWan´s,

Today i try to rollback 4.0.5 to 4.0.4 because some instability with the
following method and i crash on a problem. :-(

I shutdown oVirt Engine and make checkpoint on Engine VM ( Runs on Hyper-V,
don´t ask me way ... ). Rollback vm checkpoint to point in time before
4.0.5 update process and power up ovirt engine vm. Everything ok but, six
virtual machines that i create before this point in time does not exist on
oVirt Engine Database and all came with external-VMNAME and i can not do
nothing on them. I really think (only in my dreams ) that when ovirt engine
goes up and talk with ovirt nodes, all new vm will be automatically
discovered again. The worst thing are that i use SAN Storage Domain and
oVirt use LVM to storage VM disks, so i don´t know how to find vm disks
that ovirt engine does not recognize (external-VMNAME).

After all that, i rollback again to 4.0.5 and every vm are ok now again,
but i want to test this rollback process to 4.0.4 and do this on Production.

I think the right steps are :

1. Run engine-backup  /bin/engine-backup --mode=backup --scope=all
--file=/root/ovirt/`hostname`.`date +%d%m%Y.%H%M%S`.ovirt-engine.bkp
--log=/tmp/ovirt-engine_backup.log
2. Shutdown ovirt engine vm.
3. Make new checkpoint to rollback with something goes wrong
4. Rollback to checkpoint witch 4.0.4
5. Restore engine-backup (from version 4.0.5)
6. Start everything and check if all are ok

This is the right way to rollback from one sub release to another ( 4.0.5
to 4.0.4 ) ???
This checkpoints/snapshots of ovirt-engine VM are the best way to rollback
in time ???

Thanks in advance.

The Rest API is partially documented under https:///api/model .
It's not complete yet. All new features in 4.0 are documented and we are
working on the 'older' features now.
(contributions are welcome!)


 I'm sure no one at Redhat thought about deprecating a tool in favor
 of a new one before providing a complete user doc!


In addition, the SDK RPM itself contains many examples. See [1].
(contributions are welcome!)

Y.

[1] https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples

Although these examples, I can successfully create a snapshot, but I 
didn't find the way to delete it...

Regarding many example, it should be possible to locate any service by :
name_service = connection.system_service().name.service()

So logically it should be doable with snapshot like
snapshots_service = connection.system_service().snapshots.service()
but : AttributeError: 'SystemService' object has no attribute 'snapshots

I saw an example into the ansible [ working ] way to do the same thing 
and I found this :
snapshot = 
snapshots_service.snapshot_service(module.params['snapshot_id']).get()


How can I get this working with sdk, I mean giving snapshot_id as a

Can you provide us with the engine logs. The engine is giving an internal

highly likely there is a stack trace in the logs that will give us some idea

oVirt 4.0.5. The import completed fine and the VM runs and operates as 
expected. But I got the error cited in subject. Here’s the complete unedited 
error:

VM thays-puppet-svr has MAC address(es) 52:54:00:ce:2b:7d, which is/are out ouf 
its MAC pool definitions.

Note that is a direct copy and paste – and note the misspelling for “of” as 
“ouf”.

Will running this VM with a MAC address falling outside of the pool lead to 
problems?

AHA!!  There's a section there called "Welcome Page" which pointed me to
/usr/share/ovirt-engine/branding/ovirt.brand/welcome_page.template which
seems to be exactly what I want to edit!

Looks like I need to rewrite that in place, but that's okay.  I'm sure it
will get overwritten every update but I'll note to fix it then too.

I would never have considered this "branding"..  :)  And of course google
never brought me to that link.  I'm sure in 20/20 hindsight I would have
better search terms for "modify ovirt welcome page" that would've worked.

Thank you.

When you come from libvirt and you know what to do, you might not want to 
find/read a dedicated documentation for such a little query.

yes, sure, for read-only

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.

Re: [ovirt-users] How to execute Virsh command after ovirt installation ?

[Pavel Gashev]

Martin,

Thank you for the clarifications. It makes sense.

I just mean that following the Unix way [1] gives benefits. For example, VDSM 
doesn’t follow DOTADIW [2]. And I believe it could work better if it did.

Hi,

We were actually evaluating Pacemaker based hosted engine and talking
to Pacemaker developers, but we hit couple of show stoppers:

- Pacemaker supports limited set of nodes in the default setup (16
iirc, extensible using some kind of relays)
- It uses network based synchronization and requires very low latency
network (we can't guarantee that when migrations are in progress for
example) - the rest of oVirt currently uses storage based
synchronization, so we are in a different world here
- We would basically have to rewrite / duplicate most of the hosted
engine code we already have to get the same scheduling logic (load
penalization, gateway checks, ...)

We decided that rewriting code for no clear benefit was not productive
and stayed with the current hosted engine instead.

I am running ovirt-engine-4.0.5.5-1.el7.centos.noarch and nowhere in
/usr or /etc can I find the HTML for the ovirt-engine main page.

Yes, if I **manually type in** the link above it works just fine.  As a
courtesy to my users I want to add the CA certificate URL as a clickable
link off the ovirt main page which is accessible from
https:///ovirt-engine/

According to some googling I found that back in the 3.x days this was

Thanks, Didi.  I've read through this page and it provides lots of
goodness if I wanted to add new tabs to the portal, but I can't find any

[ovirt-users] The feature everyone was asking for is finally here...

[Eyal Edri]

FYI,

After many requests from multiple developers and testers, the oVirt CI
added a new simple job that lets you run the full fledged end-to-end oVirt
system tests with a click of a button.
You can read all the details and how-to in the new oVirt blog [1].

We wanted to allow running oVirt system tests on EVERY open patch from ANY
oVirt project, without relaying on complex building code inside the job.
Luckily we just added the 'build-on-demand' so together with it you can
build any rpms you'd like and use them to run the manual job.

So the 2 steps you'll need to do are:

   1. Write 'ci please build' inside a comment on an open oVirt patch (
   make sure the feature is enabled for that project first, its already
   available for ovirt-engine,vdsm,dashboard and vdsm-jsonrpc-java)
   2. Run the manual OST job for the version you'd like to test with the
   URLs you got from #1

You'll get and email once the job is done and you can browse the results
and check for logs from engine and the hosts.

Please feel free to ask questions on in...@ovirt.org as usual.

[ovirt-users] is there any technical guide for 3rd party appliance developers?

[Jiří Sléžka]

Hi,

it is just idea. It would be nice if there were some guide for 3rd party 
appliance developers which would describe how to prepare their 
appliances to run on oVirt without problem.


I am just oVirt/RHV administrator but we often face the situation we 
would like to run some appliance on oVirt/RHV but it is not officially 
supported (like VmWare). It would be great benefit for oVirt if you 
could break the wall of concerns and encourage 3rd party developers to 
make their appliances also fo oVirt/RHV.



Cheers,

Jiri

So it turns out that it wasn't the cluster compatibility that I missed, but
that the data center compatibility level needed to be updated to 3.6 as
well. I just didn't read the error message closely enough.

For the record, I ended up using 'yum history' to roll back the updated

Personally I don’t think ansible and ovirt-shell are

On the other hand, ovirt-shell can and is a fast/easy way

totally agree but ovirt-shell is deprecated in 4.1 et will be
removed in
4.2. Ansible or sdk4 are proposed as an alternative.


Could someone point me to an URL where sdk4 is fully documented,

The Rest API is partially documented under https:///api/model .

you mean https:///ovirt-engine/api/model
It's not complete yet. All new features in 4.0 are documented and we 
are working on the 'older' features now.

(contributions are welcome!)


I'm sure no one at Redhat thought about deprecating a tool in
favor of a new one before providing a complete user doc!


In addition, the SDK RPM itself contains many examples. See [1].

Re: [ovirt-users] How to execute Virsh command after ovirt installation ?

[Martin Sivak]

Hi,

We were actually evaluating Pacemaker based hosted engine and talking
to Pacemaker developers, but we hit couple of show stoppers:

- Pacemaker supports limited set of nodes in the default setup (16
iirc, extensible using some kind of relays)
- It uses network based synchronization and requires very low latency
network (we can't guarantee that when migrations are in progress for
example) - the rest of oVirt currently uses storage based
synchronization, so we are in a different world here
- We would basically have to rewrite / duplicate most of the hosted
engine code we already have to get the same scheduling logic (load
penalization, gateway checks, ...)

We decided that rewriting code for no clear benefit was not productive
and stayed with the current hosted engine instead.

Martin

Re: [ovirt-users] How to execute Virsh command after ovirt installation ?

[Pavel Gashev]

Migration to oVirt was requiring storage rearrangement. In other words, my 
storage was used by another virtualization.

I my case, I had no option to setup Hosted Engine since migration to oVirt 
required storage rearrangement. Now I have to run HA oVirt VM using Pacemaker + 
DRBD. Works great.

Would be great if you can share more information about your setup.
It's a great topic for an ovirt.org blog post, for example.

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.

[ovirt-users] Unable to connect to console in user portal

[Shalabh Goel]

Hi,

I have created two VMs on a node. Then I created a user and gave permission
to the user for both as UserRole from the web console. Now when I login as
the user to the user portal, I can see both the VMs. But when I click
connect or double-click on a particular VM, I get an error message "Error
while executing action VmLogon: Internal Engine Error".

The ovirt engine and node version is 4.0.

Please help

Thank You

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.

Re: [ovirt-users] How to execute Virsh command after ovirt installation ?

[Pavel Gashev]

It's interesting, I have an opposite opinion. I don’t see why oVirt reinvents 
its own HA instead of using Pacemaker. And it’s not old, it’s mature ;)

I my case, I had no option to setup Hosted Engine since migration to oVirt 
required storage rearrangement. Now I have to run HA oVirt VM using Pacemaker + 
DRBD. Works great.

Honestlly I don't see why in 2017 people still using the old DRBD + Pacemaker 
solution for virtualization stuff.

When you come from libvirt and you know what to do, you might not want to 
find/read a dedicated documentation for such a little query.

yes, sure, for read-only
but for any modification, no matter how minimal, it’s almost always needed to 
inform vdsm/engine to know about it to prevent corner cases, misdetections,

The Rest API is partially documented under https:///api/model .
It's not complete yet. All new features in 4.0 are documented and we are
working on the 'older' features now.

In addition, the SDK RPM itself contains many examples. See [1].

I personally found that she'll isn't as useful as the python sdk.
I usually open up ipython, load the sdk and interact with ovirt
directly. This is faster and much more powerful than the shell
could ever be.

okay, I suppose you to be a regular python user. Can you imagine how 
much time I spent just to understand how it works?

That is to say:

  * installing pip and not pip3 because provided
python-ovirt-engine-sdk4 is default installed to
/usr/lib64/python2.7,
  * installing ipython,
  * importing the good modules,
  * finding pertinent examples,
  * understand differences between sdk3 and 4
  * correcting some wrong examples
  * adapting example to my need?

I can't see how it can be fast for the newbie.
What's the first goal of a CLI? to abstract all this stuff for the 
python newbie. If you want a easy-to-use webadmin for attracting a 
large public, you should provide easy-to-use CLI as well. Ovirt-shell 
was a part of my choice to use ovirt.
Yes we can learn to use SDK (I dit it), but I don't think a lot people 
who chose ovirt for simplicity wll use it except advanced users.
A new time, thank you for the great stuff for the great oVirt project, 
but I find there is too much distance between devs and users.

What do really think the community about this?

  o On the doc, return values are not described

For the moment, my opinion is that ansible can't be as much

The effort of maintaining the wiki today compare to how it used to be
before is much more cumbersome and problematic.
I think we can learn a lot from wikipedia workflow,
It is a much more inviting process where anyone can change the content
easily.
I'm not saying we should let any anonymous user change the wiki but even if
we make it easier in house we can achieve much more informative reliable
and updated wiki.

Moreover, I think we shouldn't block any merging. Instead, wiki maintainers
could act afterwards and revert when needed (Wikipedia style). Another
issue is that (sadly) unlike mediawiki, we need to wait for wiki publish
after a change. So I'd suggest to build and publish the wiki at least once
a day. Any way, I think we should make the workflow much more intuitive and
pleasant like the previous wiki - i.e. much less restrictive than
manipulating a code base.

Re: [ovirt-users] high availability

[Martin Sivak]

Hi,

high availability requires power management to be configured properly for
your hosts. The VM won't be restarted until we can ascertain the status of
node2 (because it can still be up).

The host is Non responsive, meaning we do not know if it is up or down.
That is the reason we show the VM status as unknown.

You can fix that by configuring power management for node2 or by right
clicking and selecting Confirm host has been rebooted menu option.

Regards

Re: [ovirt-users] Lowering the bar for wiki contribution?

I once tried to edit a broken link in current documentation and lost hope after 
10 minutes of efforts.

Being a sysadmin, I understand the fear of unknown/untrusted people accessing 
stuff and performing uncontrolled changes, but generally speaking I believe the 
majority of this community is not driven by 10y old cracker attitudes: I trust 
that the additional value provided by people will greatly overcome a few typos

Re: [ovirt-users] Request for oVirt Ansible modules testing feedback

[Andrea Ghelardi]

Personally I don’t think ansible and ovirt-shell are mutually exclusive.
Those who are in ansible and devops realms are not really scared by making 
python/ansible work with ovirt.
From what I gather, playbooks are quite a de-facto pre-requisite to build up a 
real SaaC “Software as a Code” environment.

On the other hand, ovirt-shell can and is a fast/easy way to perform “normal 
daily tasks”.

As long as we have good documentation about how to do things, can we have and 
support both?

okay, I suppose you to be a regular python user. Can you imagine how much time

That is to say:

  *   installing pip and not pip3 because provided python-ovirt-engine-sdk4 is 
default installed to /usr/lib64/python2.7,
  *   installing ipython,
  *   importing the good modules,
  *   finding pertinent examples,
  *   understand differences between sdk3 and 4
  *   correcting some wrong examples
  *   adapting example to my need?
I can't see how it can be fast for the newbie.
What's the first goal of a CLI? to abstract all this stuff for the python 
newbie. If you want a easy-to-use webadmin for attracting a large public, you 
should provide easy-to-use CLI as well. Ovirt-shell was a part of my choice to 
use ovirt.
Yes we can learn to use SDK (I dit it), but I don't think a lot people who 
chose ovirt for simplicity wll use it except advanced users.
A new time, thank you for the great stuff for the great oVirt project, but I 
find there is too much distance between devs and users.

with the Ansible and oVirt, this[1] describes the steps you need to do,
to setup oVirt modules library and start using those modules (Most of those

If you have any issue setting this up, please contact me, I will do the
best to help you.

If you have an issue, which you think is a bug, please open an issue
here[2]. Please note that Ansible is merging it's repositories, so since
next week it will actually be stored here[3]. If you are missing
anything please open an issue as well, or just contact me, and I will
do fix it. You are also very welcome to sent PR with fixes.

For those who don't have testing environment which can test against,
I've created an Vagrant project which will deploy you the oVirt instance
using Ansible playbooks. You can find how to use it here[4].

The repository also contains few examples[5], so you don't have to
copy-paste them from the source.

Hi,
you can try to exchange the keys shown here:

if you want to use tcp without ssh look here:
http://wiki.libvirt.org/page/Libvirt_daemon_is_not_listening_on_tcp_ports_although_configured_to
basically you need to set
 * /etc/libvirtd.conf:
listen_tls = 1
listen_tcp = 1
listen_addr = "0.0.0.0"
 *  /etc/sysconfig/libvirtd:
LIBVIRTD_ARGS="--listen"
and restart libvirt but the no_verify you did works as well.

I agree, we are using the wrong tool for the job of putting initial design
for discussion.

For publishing user documentation the site is ok.

The site is intentionally not a wiki to allow OSAS some editorial
control over what goes on the public site.

I'm guessing that the scenario you are talking about here is a
developer looking to create a preliminary design document for further
