Hi Marek,

In fact all the data you need is already collected by oVirt/VDSM 
itself and saved into the DWH database.
I configured sql_exporter for prometheus which does queries on the 
DWH database to gather the data I need.
This is exported to prometheus, and there I can query all the data 
and do some alerting on for example I/O usage.

after i started this monitoring  i found that one VM is overloading

but my question is

how do you monitor IO traffic per VM? (IOPS, read/write traffic,..)

some qemu/libvirt exporter? some custom text file + node_exporter?

thanks for tips

[marek]

additional info

ovirt engine 4.5.4 on centos 8 stream

reported hypervisor/host was ovirt 4.4.9 on rocky8

problem persist after upgrade to ovirt 4.5.4 on host

BUT

on another host with the "same(1)" versions - rocky8/ ovirt 4.4.9 it 
works . same windows 11 client(my laptop)


VM guests has "same(2)" configuration


same(1) - there are differences in rocky 8 packages versions (both are 
8.7 but not update in the same time)


same(2) - manually configured

Dne 2023-06-13 v 16:18 Jean-Louis Dupond via Users napsal(a):

Depends on the error of course :)

The patches I created fixes the need to install the oVirt CA on your 
local machine.
As the console.vv file contains the oVirt CA, and with the patches 
that CA is now used to verify the certificate when connecting.

[ovirt-users] cluster level - features

[marek]

hi,

do you have tips where can i find information about new features in 
cluster levels?


i found only

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html/release_notes/data-center-and-cluster-compatibility-levels

there is only information "there are new features"


hard way i tried check

https://www.ovirt.org/release/4.5.0/

and found

https://bugzilla.redhat.com/show_bug.cgi?id=2021545

- Detecting if scratch disks can be extended automatically
- Detecting if host support disk format conversion
- Maybe for using qcow2 format by default to enable incremental backup by

https://bugzilla.redhat.com/show_bug.cgi?id=2033185

- e1000e


is there some "central" place ?

i'm not sure if grafana was used in 4.4.4 (dashboard was working)

after repeated engine-setup and playing with

/etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf

OVESETUP_GRAFANA_CORE/enable=bool:True
OVESETUP_GRAFANA_CORE/grafanaDbCreatedByUs=none:None
OVESETUP_DWH_CORE/enable=bool:True

its "somehow" solved now

Please provide more details, thanks.

Is everything set up on the same machine - engine, dwh, grafana?
If on separate machines, what's where and how was it set up?
Did you have grafana already set up in 4.4.4?
Do you have any custom local changes?

hi,

i have standalone ovirt-engine 4.4.4 (centos8 stream)

can you confirm if this upgrade path is ok?

first round
- update engine to 4.4.10
- update OS on engine to last centos 8 stream (can i upgrade to some 
point in time recommended for 4.4.10?)

- update hosts to ovirt 4.4.10
- update OS on hosts to last centos 8 stream and rocky linux 8.6

special case in first round - centos 8.2
- migrate OS on hosts from centos 8.2 to rocky linux 8.6
- update hosts to ovirt 4.4.10

second round
- update engine to 4.5.4
- update hosts to ovirt 4.5.4
- update OS on hosts - centos 8 stream - is ALREADY on last update 
from first round

- update OS on hosts - rocky linux - from 8.6 to 8.7

Wow!  Thanks.  I was unaware (newbie) of the engine-config command.  I learned a lot from 
just "engine-config -l".  LOL.
I changed "UserSessionTimeOutInterval".  Hopefully it takes effect simply by 
logging out and back in.  If not, I patiently wait until we restart the engine.

Again, thank you.

Hi Janos,

any news?

Marek


Dne 07/01/2022 v 19:00 Janos Bonic napsal(a):

Hello Marek, hello everyone,

I'm sorry I didn't update you earlier. Unfortunately, we had a key 
team member leave our team, which pushed back our release by some 
time. We are still pursuing the matter according to the original plan 
and will release the TF provider, but we will need some more time to 
work on it.


We'll keep the repository on GitHub updated with the developments we do.

Once again, I'm sorry for the delay.

Janos

Dear oVirt community,

We are making sweeping and backwards-incompatible changes to the
oVirt Terraform provider. *We want your feedback before we make
these changes.*

Here’s the short list what we would like to change, please read
the details below.

 1. The current |master| branch will be renamed to |legacy|. The
usage of this provider will be phased out within Red Hat
around the end / beginning of next year. If you want to
create a fork, we are happy to add a link to your fork to the
readme.
 2. A new |main| branch will be created and a *new Terraform
provider* written from scratch on the basis of
go-ovirt-client <https://github.com/ovirt/go-ovirt-client>.
(Preview here
<https://github.com/haveyoudebuggedit/terraform-provider-ovirt>)
This provider will only have limited functionality in its
first release.
 3. This new provider will be released to the Terraform registry,
and will have full test coverage and documentation. This
provider will be released as version v2.0.0 when ready to
signal that it is built on the Terraform SDK v2.
 4. A copy of this new Terraform provider will be kept in the
|v1| branch and backported to the Terraform SDK v1 for the
benefit of the OpenShift Installer
<https://github.com/openshift/installer>. We will not tag any
releases, and we will not release this backported version in
binary form.
 5. We are hosting a *community call* on the 14th of October at
13:00 UTC on this link
<https://bluejeans.com/476587312/8047>. Please join to
provide feedback and suggest changes to this plan.


Why are we doing this?

The original Terraform provider
<https://github.com/EMSL-MSC/terraform-provider-ovirt> for oVirt
was written four years ago by @Maigard
<https://github.com/Maigard> at EMSL-MSC
<http://github.com/EMSL-MSC/terraform-provider-ovirt>. The oVirt
fork of this provider is about 2 years old and went through rapid
expansion, adding a large number of features.

Unfortunately, this continuous rapid growth came at a price: the
original test infrastructure deteriorated and certain resources,
especially the virtual machine creation ballooned to a size we
feel has become unmaintainable.

If you tried to contribute to the Terraform provider recently,
you may have noticed that our review process has become extremely
slow. We can no longer run the original tests, and our end to end
test suite is not integrated outside of the OpenShift CI system.
Every change to the provider requires one of only 3 people to
review the code and also run a manual test suite that is
currently only runable on one computer.

We also noticed an increasing number of bugs reported on
OpenShift on oVirt/RHV related to the Terraform provider.

Our original plan was that we would fix the test infrastructure
and then subsequently slowly transition API calls to
go-ovirt-client, but that resulted in a PR that is over 5000
lines in code
<https://github.com/oVirt/terraform-provider-ovirt/pull/277> and
cannot in good conscience be merged in a single piece. Splitting
it up is difficult, and would likely result in broken
functionality where test coverage is not present.


What are we changing for you, the users?

First of all, documentation. You can already preview the
documentation here

<https://registry.terraform.io/providers/haveyoudebuggedit/ovirt/latest/docs>.
You will notice that the provider currently only supports a small
set of features. You can find the full list of features
<https://github.com/haveyoudebuggedit/terraform-provider-ovirt/milestone/1>
we are planning for the first release on GitHub. However, if you
are using resources like cluster creation, etc. these will
currently not work and we recommend sticking to the old provider
for the time being.

The second big change will be how resources are treated. Instead
of creating large resources that need to call several of the
oVirt APIs to create, we will create resource

<https://github.com/haveyoudebuggedit/terraform-provider-ovirt/milestone/1> 
we are planning for the first release on GitHub. However, if you are 
using resources like cluster creation, etc. these will currently not 
work and we recommend sticking to the old provider for the time being.


The second big change will be how resources are treated. Instead of 
creating large resources that need to call several of the oVirt APIs 
to create, we will create resources that are only calling one API. 
This will lead to fewer bugs. For example:


  * |ovirt_vm| will create the VM, but not attach any disks or network
interfaces to it.
  * |ovirt_disk_attachment| or |ovirt_disk_attachments| will attach a
disk to the VM.
  * |ovirt_nic| will create a network interface.
  * |ovirt_vm_start| will start the virtual machine when provisioned,
stop it when deprovisioned.

You can use the |depends_on| 
<https://www.terraform.io/docs/language/meta-arguments/depends_on.html> 
meta-argument to make sure disks and network interfaces are attached 
before you start the VM. Alternatively, you can hot-plug network 
interfaces later. For example:


|resource "ovirt_vm" "test" { cluster_id = "some-cluster-id" 
template_id = "some-template-id" } resource "ovirt_disk

[ovirt-users] Re: Important changes to the oVirt Terraform Provider

[marek]

hi,

*
*

*Which resources are the most important to you?
*

VM, nic*
*

*How does this change impact you?
*

rewrite current code
**

*Can we make the transition smoother for you?
*

some transition guide/tips
**

*Would you do anything differently in the light of the issues described 
above?*


no


p.s. thank you for terraform provider and publishing it to the terraform 
registry!


p.s.2 any chance that 2.0 solve this problem ?

Dne 06/10/2021 v 12:53 Janos Bonic napsal(a):


Dear oVirt community,

We are making sweeping and backwards-incompatible changes to the oVirt 
Terraform provider. *We want your feedback before we make these changes.*


Here’s the short list what we would like to change, please read the 
details below.


 1. The current |master| branch will be renamed to |legacy|. The usage
of this provider will be phased out within Red Hat around the end
/ beginning of next year. If you want to create a fork, we are
happy to add a link to your fork to the readme.
 2. A new |main| branch will be created and a *new Terraform provider*
written from scratch on the basis of go-ovirt-client
<https://github.com/ovirt/go-ovirt-client>. (Preview here
<https://github.com/haveyoudebuggedit/terraform-provider-ovirt>)
This provider will only have limited functionality in its first
release.
 3. This new provider will be released to the Terraform registry, and
will have full test coverage and documentation. This provider will
be released as version v2.0.0 when ready to signal that it is
built on the Terraform SDK v2.
 4. A copy of this new Terraform provider will be kept in the |v1|
branch and backported to the Terraform SDK v1 for the benefit of
the OpenShift Installer <https://github.com/openshift/installer>.
We will not tag any releases, and we will not release this
backported version in binary form.
 5. We are hosting a *community call* on the 14th of October at 13:00
UTC on this link <https://bluejeans.com/476587312/8047>. Please
join to provide feedback and suggest changes to this plan.


Why are we doing this?

The original Terraform provider 
<https://github.com/EMSL-MSC/terraform-provider-ovirt> for oVirt was 
written four years ago by @Maigard <https://github.com/Maigard> at 
EMSL-MSC <http://github.com/EMSL-MSC/terraform-provider-ovirt>. The 
oVirt fork of this provider is about 2 years old and went through 
rapid expansion, adding a large number of features.


Unfortunately, this continuous rapid growth came at a price: the 
original test infrastructure deteriorated and certain resources, 
especially the virtual machine creation ballooned to a size we feel 
has become unmaintainable.


If you tried to contribute to the Terraform provider recently, you may 
have noticed that our review process has become extremely slow. We can 
no longer run the original tests, and our end to end test suite is not 
integrated outside of the OpenShift CI system. Every change to the 
provider requires one of only 3 people to review the code and also run 
a manual test suite that is currently only runable on one computer.


We also noticed an increasing number of bugs reported on OpenShift on 
oVirt/RHV related to the Terraform provider.


Our original plan was that we would fix the test infrastructure and 
then subsequently slowly transition API calls to go-ovirt-client, but 
that resulted in a PR that is over 5000 lines in code 
<https://github.com/oVirt/terraform-provider-ovirt/pull/277> and 
cannot in good conscience be merged in a single piece. Splitting it up 
is difficult, and would likely result in broken functionality where 
test coverage is not present.



What are we changing for you, the users?

First of all, documentation. You can already preview the documentation 
here 
<https://registry.terraform.io/providers/haveyoudebuggedit/ovirt/latest/docs>. 
You will notice that the provider currently only supports a small set 
of features. You can find the full list of features 
<https://github.com/haveyoudebuggedit/terraform-provider-ovirt/milestone/1> 
we are planning for the first release on GitHub. However, if you are 
using resources like cluster creation, etc. these will currently not 
work and we recommend sticking to the old provider for the time being.


The second big change will be how resources are treated. Instead of 
creating large resources that need to call several of the oVirt APIs 
to create, we will create resources that are only calling one API. 
This will lead to fewer bugs. For example:


  * |ovirt_vm| will create the VM, but not attach any disks or network
interfaces to it.
  * |ovirt_disk_attachment| or |ovirt_disk_attachments| will attach a
disk to the VM.
  * |ovirt_nic| will create a network interface.
  * |ovirt_vm_start| will start the virtual machine wh

hi,

i need test environment for centos6 system

on new ovirt installation downloaded CentOS 6 Generic Cloud Image

created new VM from from this cloud image but VM cannot find disk 
(console shows "pres any key to boot")


tried legacy BIOS and UEFI too - nothing changed

so i tried install centos6 from ISO . works. then i made template 
from this VM.



WARNING: this is incorrect information! centos6 installed from ISO is 
not booting too. sorry


so i cannot boot centos6 on 4.4.8 in any way :(

how terraform knows which nic_configuration {} from ovirt_vm belongs to 
which resource "ovirt_vnic"?


my problem is that VM has paired nic_configuration(eth0) with resource 
"ovirt_vnic" "eth1" and vice versa


any hints?


https://github.com/oVirt/terraform-provider-ovirt/blob/master/ovirt/resource_ovirt_vm.go#L967
my experience with Go is not enough to understand how is "pairing" done

Re: [ovirt-users] [ovirt-devel] Cockpit oVirt support

[Marek Libra]

Regarding libvirt, there's fallback to Libvirt provider (part of
cockpit-machines) for VMs which are not managed by oVirt.
For the oVirt ones, oVirt API handles all the actions.

It's not yet implemented, but I'm considering to fallback to Libvirt for
selected actions in case the oVirt API can't be reached. Like for shut down
[1].

Anyway, there's still open question with the Libvirt connection since it's
secured on an oVirt host.

[ovirt-users] Announcing VM Portal 0.1.4

[Marek Libra]

Hello All,

Let me announce availability of the VM Portal v0.1.4 for preliminary
testing.
We are looking forward to your feedback which we will try to incorporate
into oncoming stable 1.0.0 version.

The VM Portal aims to be a drop-in replacement of the existing Basic User
Portal.
Revised list of Extended User Portal features will be implemented to
ideally replace it as well.

The VM Portal is installed by default since oVirt 4.1.

*The simplest way to try latest version is via Docker by [1].*
Once oVirt credentials are entered and initialization is finished, you can
access it on [2].

If you prefer to stay as closest to the production setup as possible, the
latest rpms are available on project's yum repo [3].
Then you can access the portal from [4].

Prerequisites: The VM Portal requires ovirt-engine 4.0+, so far mostly
tested on 4.1.

Please note, the docker image is so far meant to just simplify user testing
and is not ready for production setup.
Unless decided otherwise in the future, stable releases are still planed to
be deployed via rpms.

For issue reporting or enhancement ideas, please use project's github issue
tracker [5].

Thank you for your feedback,
Marek

[ovirt-users] New User Portal - gathering feedback

[Marek Libra]

Hi,

with ovirt-4.1.0_beta2, new Basic User Portal is introduced, so far as tech
preview.
To try, please follow the new "Basic User Portal" link from the main page.

Recently most of previous (GWT based) Basic User Portal's functionality is
available.
In plan is full conformity and selected features of recent Extended Portal.

Following goals were stated for this project:
- improve UX by
  - modern UI (conforms Patternfly 3)
  - faster UI responses
- shareable
  - built from reusable components to share portions of the UI in other
projects (like ManageIQ)
- POC for ongoing oVirt UI development
  - one of the options for next-gen oVirt UI to consider

>From technical perspective, the project is based on
- oVirt REST API
- React/Redux/Saga
- Patternfly 3
- pure JavaScript App without server-side processing except the existing
REST API

So far, the project is tech preview to gather user feedback.

Please share your comments and ideas, it will really help with ongoing
development.
Real-life use-cases (both existing or potential) will be much appreciated.

Thanks,
Marek

Subject: problems with power management using idrac7 on r620

Hi.

I've been having problem with power management using iDRAC 7 EXPRESS on
a Dell R620.  This uses a shared LOM as opposed to Enterprise that has a
dedicated one.   Every now and then, idrac simply stops responding to
ping, so it can't respond to status commands from the proxy.  If I send
a reboot with ipmitool mc reset cold command, the idrac reboots and
comes back, but after the problem has occurred, even after a reboot, it
responds to ping, but drops 80+% of packets.  The only way I can solve
the problem is to physically restart the server.This isn't just
happening on  one R620 - it's happening on all of my ovirt hosts.  I
highly suspect it has to do with a memory leak, and being monitored by
engine causes the problem.I had applied a recent firmware upgrade
that was supposed to solve this kind of problem, but it doesn't.  In
other to provide Dell with more details, can someone tell me how often
each host is being queried for status?  I can't seem to find that info.
The idrac on my file server doesn't seem to exhibit the same problem,
and I suspect that is because it isn't being queried.

Hi,

fence agent for IPMI is based on ipmitool. So if ping/ipmitool is not 
working there is not much to do about it. I don't know enough about 
oVirt engine but there is no real place where fence agent can memory 
leak because it does not run as daemon.

Subject: [ovirt-users] ilo4 vs. ipmilan fencing agents

Hi all --

I'm trying to get fencing squared away in my cluster of hp dl-380 servers,
which come with ilo4. I was able to get a successful status check from
the command line with fence_ilo4, but not w/ the ilo4 option in ovirt.

I see, though, that ilo4 in ovirt just maps to fence_ipmilan, and I was
not able to get a successful status check w/ fence_ipmilan from the cli.

So, I tried resetting the mapping so that ilo4 maps to ilo4. Now I can
complete the power management test in ovirt, but I imagine there's some
reason why ovirt isn't configured this way by default.

Will fencing actually work for me with ilo4 mapped to ilo4, rather than
to ipmilan?

ILO3 and ILO4 are mapped implicitly to ipmilan with lanplus flag ON and 
power_wait=4
If you change the mapping to use the native scripts its OK as long as it works 
for you

Marec, should we always map ILO3  ILO4 to the native scripts (fence_ilo3 , 
fence_ilo4) and not to ipmilan ???

yes, it is better but adding arguments manually is fine also.

If this is an absolute must, I'm sure I can arrange to give someone 
external access to one of these devices, but it won't be without 
*additional* significant effort on my part.


Let me know what I can do to help resolve this.

For upstream it is not a problem but for RHEL accepting it will mean 
that we will support this for X years (X  10) for every customer.


I'm developer, so I'm not the one who decides what should be included - 
please use the official channel, so it will be read by right people.

we still can't distinguish at feature level by hypervisor support.
so adding this to engine will fail for any .el6 distro, until/if this 
is added to rhel 6.6, etc.

[internal]

Support for Raritan will not be added to rhel6.6/rhel7 until our QA will 
have access to this device for testing (or partner will test it for us). 
We do not have such criteria for upstream.

We use Raritan / Dominion PX remote power blocks, is there a 
way to

easily add support for these?


CCing Marek on that in case that he had something to add from the

fence-agents view since it may be already supported implicitly (like
drac7 that is using actually ipmilan)



No, Raritan are not supported yet (rhbz#519731)



so david, if you can try to push the raritan support to 
fence-agents, the

ovirt side is usually just a config change.

Unfortunately it looks like fencing.py is where the legacy --option 
was translated to --action. I believe ovirt calls fencing.py as a 
proxy to execute fence_raritan?


The version of fence-agents I pulled from git has the backwards 
compatibility removed;
https://lists.fedorahosted.org/pipermail/cluster-commits/2013-February/003090.html 



So if I added support for it in fence_raritan I'm not sure it would 
work (I can try) but also the fence-agents guys probably wouldn't take 
the submission to have it added to future code.


Those legacy options where completely removed from v4.0 - there is an 
another branch v3.9.x which is based on new code but with all legacy 
options, it is possible that it will be one day ported to RHEL6 but it 
is not a priority right now.
