Server `resources.ovirt.org` hosting repositories for ovirt is going to be
migrated to new hardware in a different datacenter within the next couple
No service interruption is expected during the migration. I will follow-up
when the process is complete
Ineed your help to understand how to configure the network of a new
Mynew system will have a 4.3 engine thatruns in a virtual machine, andsome
Dell R7525 AMD EPYC hypervisors, eachholding two 4-port PCI network cards.
These servers will have node-ovirt image again in version 4.3.
As for the network, there are two HPE Aruba 2540G, non-stackable, with
24 1Gbs ports
and 2 10Gbs uplinks to the star center.
This is a simplified scheme:
My goal is to make the most of the server's 8 ethernet interfaces to have
both reliability and maximum possible throughput.
This cluster will have two virtual networks, one forovirt management and
the traffic of individual virtual machines.
With that said here's what my idea is. I would like to have two links
aggregated by 4Gbs,
one for ovrtmgt and the other for vmnet.
With the ovirt web interface I can createan active-passive "Mode 1"
bond, but this
won'tallow me to go beyond 1Gbs. Alternatively I could create a "Mode 4"
802.3ad but unfortunately the switches are not stacked and therefore not
this solution applies.
This is an example with active passive configuration:
Can you tell me if ovirt can generate//nested bonds? Or do you have
other solutions ?
Thanks a lot !

On CentOS 8 Stream I get the following error during "hosted-engine --deploy":
[ INFO ] The host has been set in non_operational status, deployment errors: code 156: Host HOST moved to Non-Operational state as host CPU type is not supported in this cluster compatibility version or is not supported at all, code 519

I set up cluster compatibility but it did not solve the problem.
On a normal CentOS 8.4 system, the error is not present.
Does anyone have an idea?
Or have older drivers been removed from the Streram version?
I have question.
When we commit the snapshot ,any subsequent snapshots are erased.
What is the reason for this design？
If I don’t want to erased the subsequent snapshots, is there a way to configure it?
My requirement is that after the pre-snapshot is submitted, the subsequent snapshots can still be used.
Any one can help me ?
I'm setting up a fairly (?) complex oVirt over Gluster setup built around 3
Xeon servers-turned-into-workstations, each doubling as oVirt node + one
primary Fedora VM w/ a dedicated passthrough GPU (+audio and a couple of
USB root devices).
One of the servers seems to have some weird issue w/ the passthrough nVidia
GPU that seems to require me to edit the VM iommu (1) and passthrough
device (2) command line.
I tried using the qemu-cmdline addon to add the missing parameters, but it
seems that qemu treats the added parameters as an additional device / iommu
instead of editing the existing parameters.
1. How can I view the VM qemu command line?
2. Can I somehow manually edit the qemu command line, either directly or by
somehow adding parameters in the HE XML file?
 iommu: VM XXX is down with error. Exit message: internal error: qemu
unexpectedly closed the monitor: 2021-11-05T14:59:44.499366Z qemu-kvm: We
need to set caching-mode=on for intel-iommu to enable device assignment
with IOMMU protection.
 GPU: May need to add x-vga=off,
Hi, can you please help me?
I deployed ovirt on an AWS instance, created a vm but during generation .vv the file, an private IP is put in the host field instead of an public one, which is why the remote-viewer does not connect to the vm. If I change the host from an private IP to an public one, then everything works. Where and how can I change this field ?
After doing a a backup and restoring to a new oVirt management server check for upgrade of hosts fails.
Also reinstall and enroll certificate fails.
The error message is

Also removing and adding a host back fails
