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?
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

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

oVirt Code of Conduct:
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.
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
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
btw. oVirt is great product and HCI looks really functional and usable
(with 10GE network and SSDsof course). Big thanks to developers and

Any info if it is fixed in the latest 4.4.6? It seems no update inside the

Are there currently any known issues with using libgfapi in the latest
stable version of ovirt in hci deployments? I have recently enabled it and
have noticed a significant (over 4x) increase in io performance on my vms.
I’m concerned however since it does not seem to be an ovirt default
setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?
I have 2 independent Hyperconverged Sites/Data Centers.
Site A has a GlusterFS Replica 3 + Arbiter Volume that is Storage Domain data2
This Volume is Geo-Replicated to a Replica 3 + Arbiter Volume at Site B called data2_bdt
I have simulated a DR event and now want to import the Ge0-Replicated volume data2_bdt as a Storage Domain on Site B. Once imported I need to import the VMs on this volume to run in Site B.
The Geo-Replication now works perfectly (thanks Strahil) but I haven't been able to import the Storage Domain.
Please can someone point me in the right direction or documentation on how this can be achieved.
Having installed oVirt 4.4.4 HCI 3 node cluster, the Grafana 'Monitoring Portal' was not visible on the Default page.
It appears that Grafana is installed but not configured.
I have checked a 4.4.3 environment and it is installed and running, so is this a bug with 22.214.171.124-1.el8?
Any help would be appreciated.
