Restored engine backup: The provided authorization grant for the auth code has expired.
by Nicolás
Hi,
I'm restoring a full ovirt engine backup, having used the --scope=all
option, for oVirt 4.3.
I restored the backup on a fresh CentOS7 machine. The process went well,
but when trying to log into the restored authentication system I get the
following message which won't allow me to log in:
The provided authorization grant for the auth code has expired.
What does that mean and how can it be fixed?
Thanks.

This year conference community updates
by Sandro Bonazzola
Hi,
as announced we are going to have oVirt online conference coming in
September.
I would like to give usual community updates in and as part of that I'd
like to report about oVirt downstream products (such as Red Hat
Virtualization and Oracle Linux Virtualization Manager) and about companies
using oVirt.
I could just go googling and guessing by e-mail traffic on oVirt users list
but I want to try a different approach this year.
So, if you are shipping an oVirt downstream or if you're using oVirt and
you'd like to get the company nominated during the community reports please
let me know off-list.
Also I'd like to remind that oVirt site has a section dedicated to user
stories, if you want to share yours you can either push it to
https://github.com/oVirt/ovirt-site or get in touch with me off-list to get
help getting your story published.
Thanks,
--

Re: CPU Compatibility Problem after Upgrading Centos 8 Stream Host
by Gunasekhar Kothapalli
The issue was with edk2-ovmf package update, rolling that package back and
it started recognizing the CPU and host coming up... tested on one host and
worked fine.

Already trying several things, seem kernel update doesn't make this problem

happened.

I also end up with the same problem today. How did rollback yum i see many
yum updates in the yum history.
Here is what the error says.
The host CPU does not match the Cluster CPU Type and is running in a
degraded mode. It is missing the following CPU flags: model_IvyBridge,
spec_ctrl. Please update the host CPU microcode or change the Cluster CPU
Type.

Requirements to put to cluster version 4.6
by Gianluca Cecchi
Hello,
I updated all my 3 CentOS 4.4.5 hosts to 4.4.6.
Or at least upgrading them from the GUI I see now they are on CentOS 8.4
and:
[root@ov200 ~]# rpm -qa| grep 4.4.6
ovirt-release44-4.4.6.3-1.el8.noarch
ovirt-host-4.4.6-1.el8.x86_64
ovirt-host-dependencies-4.4.6-1.el8.x86_64
[root@ov200 ~]#
How to see from the webadmin GUI or from the Host Console that they are
indeed 4.4.6?
If I try to set cluster compatibility version to 4.6 I get:
Error while executing action: Cannot change Cluster Compatibility Version
to higher version when there are active Hosts with lower version.
-Please move Host ov300, ov301, ov200 with lower version to maintenance
first.
I don't remember the need of giving downtime to get new cluster version...
Or what are further requirements (and benefits....) to upgrade to 4.6?
Thanks,
Gianluca

Removing Direct Mapped LUNs
by Ryan Chewning
Hi List,
We need to add and remove directly mapped LUNs to multiple VMs in our
Non-Production environment. The environment is backed by an iSCSI SAN. In
testing when removing a directly mapped LUN it doesn't remove the
underlying multipath and devices. Several questions.
1) Is this the expected behavior?
2) Are we supposed to go to each KVM host and manually remove the
underlying multipath devices?
3) Is there a technical reason that oVirt doesn't do this as part of the
steps to removing the storage?
This is something that was handled by the manager in the previous
virtualization that we used, Oracle's Xen based Oracle VM.
Thanks!

upgrading to 4.4.6 with Rocky Linux 8
by Jason Keltz
Hi..
I'm looking to migrate soon from CentOS 7.9 with oVirt 4.3.10 to Rocky
Linux 8.4 with oVirt 4.4.6. I'm working on my kickstart of my
standalone engine in a VM at the moment.
So far, with minimal experience with Rocky Linux, after my kickstart, I
was able to run "engine-setup", follow all the defaults and then access
my "new" engine via web. I have to explore the actual procedure for
installing on my current engine host, and restoring my data.
When oVirt team releases new releases, I'm just wondering if you test
going from the last previous release (4.3.10 in this case) to each
latest release? I know that the documentation says we always need to
make sure we update to each individaul major release, but I'm just
wondering if this is something that oVirt team tests with each release?
I'm very concerned for potential of failed upgrade, and the potential
headaches that it could cause.
I see the 4.4.6 was released in time with RHEL 8.3. I'd like to use
Rocky Linux 8.4 because I believe RHEL has re-enabled mptsas (though I
know still unsupported) from 8.4+ which will make things easier.
Any additional suggestions or caveats of the upgrade?
Thanks for any feedback,
Jason.

upgrading gluster brick os from CentOS7 to 8
by Jiří Sléžka
Hello,
I'm in progress of moving my oVirt HCI cluster to production. It was a
bit complicated process because I had two new servers to install oVirt
from scratch in the lab and three old servers with standalone kvm
hypervisors in production. One of them (installed with CentOS7) was good
enough to join HCI cluster. All three old kvm servers had production vms
running on them.
New cluster was installed with CentOS8 and oVirt4.4, I started with
single node, then expanded it to two hosts with one another which acts
as arbiter (just for stability in lab envirnment).
After some testing and tuning I moved this two node cluster (without
arbiter node) to my server housing. Then I prepared gluster brick on
that one old server which I want reuse and join it to gluster storage so
now it is replica 3 - two nodes are CentOS8 based and acts as oVirt
hosts, one is CentOS7 and acts also as standalone kvm hypervisor.
Then I migrated all vms from standalone kvm hypervisors to oVirt, then
switched off two oldest hosts.
Now I would like to reinstall CentOS7 node to oVirt host. My plan is to
keep gluster brick fs and backup configuration and restore it after
reinstall to CentOS8 as mentioned in
https://mjanja.ch/2018/08/migrate-glusterfs-to-a-new-operating-system/.
I want to speed up gluster healing. Does it make sense?
Now the questin: Brick fs was created on CentOS7 and don't have new xfs
features FINOBT,SPARSE_INODES,REFLINK. Could it be problem? Will be
better to recreate fs in CentOS8 and then do full heal? I am afraid that
it will take a long time and make big load to production hosts.
TL;DR: Does gluster/oVirt4.4 make use of FINOBT,SPARSE_INODES,REFLINK
xfs features?
btw. oVirt is great product and HCI looks really functional and usable
(with 10GE network and SSDsof course). Big thanks to developers and
community!
Cheers,
Jiri

It seems I have the same problem with my 4.4.5.
Any info if it is fixed in the latest 4.4.6? It seems no update inside the

CentOS 8 to Stream conversion
by Gary Pedretty
I have moved all my hosts from CentOS 8 to Stream, but the hosted engine is still Centos 8. Is it safe to use the same conversion of the hosted-engine from 8 to Stream while in global maintenance mode?
IE:
dnf swap centos-{linux,stream}-repos
dnf distro-sync
Thanks
Gary
