[ANN] oVirt updates
by Sandro Bonazzola
oVirt community,
Today marks a new day in the 26-year history of Red Hat. IBM has finalized its acquisition of Red Hat, which will operate as a distinct unit within IBM moving forward.
What does this mean for Red Hat’s contributions to the oVirt project?
In short, nothing.
Red Hat always has and will continue to be a champion for open source and projects like oVirt that have played such a large role in driving innovation in the virtualization space. IBM is committed to Red Hat’s independence and role in open source software communities so that we can continue this work without interruption or changes.
Our mission, governance, and objectives remain the same. We will continue to execute the existing project roadmap as we’ve been doing since 2011 for the oVirt project. Red Hat associates will continue to contribute to the upstream in the same way they have been. And, as always, we will continue to help upstream projects be successful and contribute to welcoming new members and maintaining the project.
We will do this together, with the community, as we always have.
If you have questions or would like to learn more about today’s news, I encourage you to review the materials below. Red Hat CTO Chris Wright will host an online Q&A session in the coming days where you can ask questions you may have about what the acquisition means for Red Hat and our involvement in open source communities. Details will be announced on the Red Hat blog [1].

Managed Block Storage
by dan.poltawski＠tnp.net.uk
I'm testing out the managed storage to connect to ceph and I have a few questions:
* Would I be correct in assuming that the hosted engine VM needs connectivity to the storage and not just the underlying hosts themselves? It seems like the cinderlib client runs from the engine?
* Does the ceph config and keyring need to replicated onto each hypervisor/host?
* I have managed to do one block operation so far (i've created a volume which is visible on the ceph side), but multiple other operations have failed and are 'running' in the engine task list. Is there any way I can increase debugging to see whats happening?

Storage domain format version info
by Gianluca Cecchi
Hello,
part of updating a DC from 4.2 to 4.3 consists in updating format of data
storage domains from V4 to V5.
Questions:
- where can I find list of differences between V4 and V5? And in general
between previous ones?
- can I force only a particular storage domain to remain in V4 while having
the other ones upgraded to V5, for any reason? Or the reverse: update only
one of the defined domains?
Eg on oVirt web site I only found this for V4
https://www.ovirt.org/develop/release-management/features/storage/storage...
with mention about Qcow2 v3 (link broken.. one ot the upstream pages for it
here:
https://wiki.qemu.org/Features/Qcow3 ) that should give near raw
performance with advantages of qcow2 format...
Thanks,
Gianluca

Ovirt Secure boot issues
by Strahil
Hello All,
I would like to ask any of you to do a simple test.
Please install a linux on a VM with Secure boot and after the install wizzard is over -power it off and then on.
Here is what I have observed:
1. UEFI forgets the certificates after a poweroff and asks for the openSUSE certificate every time. Rebooting from the VM doesn't cause any problems till nextg boot.
2. RHEL8 grub menu consists only of 'System setup'.
When you select it - you are sent to the UEFI menu. If you select continue - everything is fine.
Poweroff + Poweron makes everything to repeat.
Do you observe the same issues. If I'm not the only one hitting this - I will open a bug, otherwise I will try to further debug this.
Best Regards,
Strahil Nikolov

VM lost conection.
by Julio Cesar Bustamante
Hi there,
I have a problem, Last week I lost connectivity a VM with OS Windows server
2008 I access to check it and
in ovirtmanager that VM is power on and I could login it, but there was no
ping to other VM machines So I
restarted VM and I recovery connectivity. Today It shows the same scenario
with same VM.
I checked log from ovirtmananer and ovirt node from running VM but I didnt
find any error.
Where can I find out more ?
I have a Ovirtmanager 4 and a Ovirtnode 4.1

Re: HE deployment failing
by Strahil
Yes,
But I thought that cockpit should prevent creation of the gluster volume 'engine' as it is too small.
@Dev
Do we have such control ?

HE deployment failing
by Parth Dhanjal
Hey!
I'm trying to deploy a 3 node cluster with gluster storage.
After the gluster deployment is completed successfully, the creation of
storage domain fails during HE deployment giving the error:
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Error:
the target storage domain contains only 46.0GiB of available space while a
minimum of 61.0GiB is required If you wish to use the current target
storage domain by extending it, make sure it contains nothing before adding
it."}
I have tried to increase the disk size(provided in storage tab) to 90GiB.
But the deployment still fails. A 50GiB storage domain is created by
default even if some other size is provided.
Has anyone faced a similar issue?
Regards
Parth Dhanjal

Re: UI - cannot remove disk whiel system is running
by Strahil
Everything ended well - despite the warning 'do not shutdown' I powered off and powered on the VM.
This action allowed me to trigger a snapshot deletion (again) and it completed successfully.
Removing the disk of interest also completed successfully.
So, I got a happy ending.
Best Regards,
