CPU Compatibility Problem after Upgrading Centos 8 Stream Host
by Nur Imam Febrianto
Hi,
This morning I have a problem that suddenly my Host (Using Centos 8 Stream, not oVirt Node) showing error with Cpu Compatibility. It says my CPU doesn’t have Haswell-noTSX and spec_ctrl flag. After downgrading the kernel back from 4.18.0 – 305 to 4.18.0 – 301.1 and rollback yum update, it working again. Do anybody having same issue ?
I’m using Xeon E5-2695v4 with cluster compatibility Secure Intel Haswell. Using oVirt 4.4.6 on CentOS Stream host.
Thanks before.

Re: Import Ge0-Replicated Storage Domain fails
by Simon Scott
Just to clarify...
Site A has volume data2 which geo-replicates to Site B
Site B has volume data1 which geo-replicates to Site A
I will look at the engine upgrade and ansible today.

Cluster stuck in maintenance - Hosts not upgrading as expected
by David White
I have a 3-node hyperconverged cluster with Gluster filesystem running on RHEL 8.3 hosts.
It's been stable on oVirt 4.5.
Today, I just upgraded the Engine to v4.6.
[Screenshot from 2021-05-22 20-29-23.png]
I then logged into the oVirt manager, navigated to Compute -> Clusters, and clicked on Upgrade.
The Status of the cluster does have an exclamation mark that says "Upgrade Cluster Compatibility Level", but my understanding is, I shouldn't do that until all 3 of my hosts have been upgraded.
Looking at active tasks, I see that the first host in my cluster is stuck in "Upgrading".
It's now been like this for 3 hours, without any visible progress.
If I try to launch a VM that is not configured for high availability, the VM fails to launch, and I get a message about the cluster being in "Maintenance Mode" and that none of the hosts satisfies current scheduling restraints.
How do I....
a) Cancel / clear the upgrade and take the cluster out of "maintenance mode"
b) Properly upgrade the cluster, since clicking the "Upgrade" button clearly didn't work?
Thanks,
David

cleanup does not cleanup
by lejeczek
Hi guys.
-> $ ovirt-hosted-engine-cleanup -q
says it ran its stuff, done & dusted yet I see 'ovirtmgmt'
bridge remains.
Would that be a bug and how to clean it?
many thanks, L.

Problems provisioning 4.4.6 hosted engine
by Sketch
This is a new system is CentOS 8.3, with the oVirt-4.4 repo and all
updates applied. When I try to install the hosted engine with my engine
backup from 4.3.10, the installation fails with a too many open files
error. My 8.3 hosts already had 1M system max files, which is more than
any of my CentOS 7/oVirt 4.3 hosts have. I tried increasing it to 2M with
no luck, so my suspicion is that the error is on the engine itself?
I tried provisioning a new engine just to test, and I get SSH key errors
instead of this one.
Any suggestions?

Import to VMware
by Darin Schmidt
Hello,
Ive exported an OVA of a server we had made on OVIRT and Im trying to import it to VMware. Its complaining that the ovf:format is incorrect.
ovf:format="http://www.gnome.org/~markmc/qcow-image-format.html"
That link doesnt resolve to anywhere because it appears its now http://people.gnome.org/~markmc/qcow-image-format.html
But I dont know whats supposed to go there nor have I been able to locate anything to help solve this issue. All I really need is access to the files in the, what I assume is, vdmk file that comes along with the ovf file, which mine is called: 154b3d77-d340-4d24-a448-66265c5fb613
So if anything, is there a way to open this vm disk so I can gain access to the files?
Thanks

Error Adding host to cluster
by David Johnson
When I attempt to install a new host to my cluster from the GUI I get this
set of errors/warnings, and the install fails.
- Host has no default route
- The Host CPU does not match the Cluster CPU Tye and is running in a
degraded mode. It is missing the following CPU flags: vmx,
model_Cascadelake-Server-noTSX.
The new host has a brand new bare centos 8 installation on it. It
successfully installed from the internet.
The *new host* hardware is 48x Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
The *pre-existing host* is 64x Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz
If I am reading the ansible logs correctly, ansible is failing to find the
*ovirt-hosted-engine-setup* package, which is confusing since I have a
separate physical machine for the engine (which I am using to install
from), and don't want a self hosted engine.
Any advice would be welcome.

I am trying to setup ovirt hosted engine.
by Ken.Germann＠L3Harris.com
I select eth2 as the default interface for the management network for the VM network.
I get this error:
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The selected network interface is not valid"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook
It appears to be expecting a bridge interface to be setup...
Thank You,
