Re: oVirt reboot fails
by Strahil Nikolov
It seems that you are using EFI and something corrupted the installation.
The fastest approach is to delete the oVirt node from the UI, reinstall and readd it back via the UI.
I suspect something happened with your OS FS, but it could be a bug in the OS.
If it was a regular CentOS Stream system, I wiuld follow https://access.redhat.com/solutions/3486741

New oVirt self-hosted engine deployment : design ideas
by ravi k
Hello,
We are creating a self-hosted engine deployment and have come up with a draft design. I thought I'll get your thoughts on improving it. It is still a test setup and so we can make changes to make it resilient.
We have four hosts, host01..04. I did the self-hosted engine deployment on the first node which created a dc, cluster01 and a storage domain hosted_storage. I added host02 also as a self-hosted engine host to cluster01.
Now the questions :-)
1. It is recommended not to use this SD hosted_storage for regular VMs. So I'll create another SD dc_sd01. Should I use this dc_sd01 and cluster01 when creating regular VMs? What's the best practice?
2. It is a bit confusing to get my head around this concept of running regular VMs on these self-hosted engine hosts. Can I just run regular VMs in these hosts and they'll run fine?
3. Please do suggest any other recommendations from experience in terms of designing the clusters, storage domains etc. It'll help as it is a new setup and we have the scope to make changes.
Regards,
Ravi

Important changes to the oVirt Terraform Provider
by Janos Bonic
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 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" "test" {
storagedomain_id = "some-storage-domain-id"
format = "cow"
size = 512
alias = "test"
sparse = true
}
resource "ovirt_disk_attachment" "test" {
vm_id = ovirt_vm.test.id
disk_id = ovirt_disk.test.id
disk_interface = "virtio_scsi"
}
resource "ovirt_vm_start" "test" {
vm_id = ovirt_vm.test.id
depends_on = [ovirt_disk_attachment.test]
}
The next change is the availability of the provider on the Terraform
Registry. You will no longer have to download the binary. Instead, you will
be able to simply pull in the provider like this:
terraform {
required_providers {
ovirt = {
source = "ovirt/ovirt"
version = "..."
}
}
}
provider "ovirt" {
# Configuration options
}
The configuration options for the provider itself have also been greatly
expanded, see the preliminary documentation
<https://registry.terraform.io/providers/haveyoudebuggedit/ovirt/latest/docs>
for details.
What’s changing behind the scenes?
The new Terraform provider is a complete rewrite based on the
go-ovirt-client <https://github.com/ovirt/go-ovirt-client> library. The
single biggest advantage of this library is that it has built-in mocks for
all resources it supports. Having mocks allows us to run tests without
needing to spin up an oVirt instance. We have already configured GitHub
Actions
<https://github.com/haveyoudebuggedit/terraform-provider-ovirt/actions> on
the new provider and all changes are automatically checked against these
mocks.
We may decide to add an end-to-end test later, but for the foreseeable
future we will trust the correctness of the mocks to test community
contributions. This means that we will be able to merge changes much
quicker.
On the OpenShift side we will also switch to using the new provider, since
this is the primary motivation for the change. The OpenShift Installer uses
the legacy version 1 of the Terraform SDK, so we will maintain a version
1-compatible copy in the v1 branch, which the installer can pull in. It is
important to note, however, that the v1 branch will be a pure backport, we
will not develop it separately. Development will be focused on the version
in main that is being released to the Terraform Registry.
What does this mean to you, the contributors?
The current Terraform provider has several pull requests open
<https://github.com/oVirt/terraform-provider-ovirt/pulls>. Unfortunately,
we currently do not have the capacity to properly vet and and run our
internal test suite against these changes. In contrast to the new Terraform
provider, we do not have working tests, linting, and the code structure
that make merging changes easier.
We are very sorry to say that *these patches are unlikely to be merged*. We
know that this is a terrible thing, you have put in effort into writing
them. Unfortunately, we do not see an alternative as there already numerous
bugs on our radar and adding more code would not make the problem go away.
We want to hear your opinion
As the owners of the original Terraform provider we haven’t been keeping up
with reviewing your contributions and issues. Some are several months old
and haven’t received answers for a long time. We want to change that, we
want to hear from you. Please join our community round table around the
Terraform provider on the 14th of October at 13:00 UTC on this link
<https://bluejeans.com/476587312/8047>.
*We want to know: Which resources are the most important to you? How does
this change impact you? Can we make the transition smoother for you? Would
you do anything differently in the light of the issues described above?*

Unable to upload ISO Image in ovirt 4.4.10
by louisb＠ameritech.net
I recently installed ovirt 4.4.10 on my server successfully; however; I'm unable to upload images using the ovirt GUI. I tried the following:
Storage> Disk> Upload> Start > Completed the form pointing to the source location of the image
Once I click the OK button the status of the image go's into a Locked Status then switches to "Paused by System" and jsut hangs from there.
A few days later I tried to delete the upload because the state did not change. I tried the following to Cancel the upload:
Storage> Disk> Upload> Cancel
Once the above is complete the status changes to "Finalizing Cleanup".
What should be done to resolve this issue?
Thanks

Importing KVMs and QCOW
by Abe E
Hey Everyone
So one thing that hasnt been clear for me is method for importing KVMs and QCOW images to ovirt.
I have had some success with importing some VMs in KVM format by building a VM of same size and then replacing the image file based on its disk ID.
My issue so far has been with some premade qcow and sometimes KVMs dont successfully work with the above method. Is it not possible to simply upload to the disk page in the GUI and attach it to the VM, what am I doing wrong here?
Thanks in advance

NFS Synology NAS (DSM 7)
by Maton, Brett
Hi List,
I can't get oVirt 4.4.8.5-1.el8 (running on oVirt Node hosts) to connect
to an NFS share on a Synology NAS.
I gave up trying to get the hosted engine deployed and put that on an
iscsi volume instead...
The directory being exported from NAS is owned by vdsm / kvm (36:36)
perms I've tried:
0750
0755
0777
Tried auto / v3 / v4_0
As others have mentioned regarding NFS, if I connect manually from the
host with
mount nas.mydomain.com:/volume1/ov_nas
It connects and works just fine.
If I try to add the share as a domain in oVirt I get
Operation Cancelled
Error while executing action Add Storage Connection: Permission settings on
the specified path do not allow access to the storage.
Verify permission settings on the specified storage path.
When tailing /var/log/messages on
When tailing /var/log/messages on the oVirt host, I see this message appear
(I changed the domain name for this post so the dots might be transcoded in
reality):
Aug 27 17:36:07 ov001 systemd[1]:
rhev-data\x2dcenter-mnt-nas.mydomain.com:_volume1_ov__nas.mount:
Succeeded.
The NAS is running the 'new' DSM 7, /etc/exports looks like this:
/volume1/ov_nas x.x.x.x(rw,async,no_root_squash,anonuid=36,anongid=36)
(reloaded with exportfs -ra)
Any suggestions appreciated.
Regards,
Brett

Import an snapshot of an iSCSI Domain
by Vinícius Ferrão
Hello,
I need to import an old snapshot of my Data domain but oVirt does not find the snapshot version when importing on the web interface.
To be clear, I’ve mounted a snapshot on my storage, and exported it on iSCSI. I was expecting that I could be able to import it on the engine.
On the web interface this Import Pre-Configured Domain finds the relative IQN but it does not show up as a target.
Any ideas?
