Hello,
We are planning to install self-hosted engines in our production and DR
locations which are separated physically. VMware's vcenter has a feature
wherein we can link vcenters so we can access both DCs in the same console.
Do we have something like that in oVirt as well? I was searching
The thread
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/CD5WDA2Y77MHQOV73DQ5UA7W3YO7COUY/
also suggests using ManageIQ. I'll read more on that to find out.

I tried this and it didn't work. In 4.3 the option to change the switch type is
not allowed. I still changed the switch type of ovirtmgmt in the file and
rebooted. But it didn't have any effect.
Isn't there a way we can specify OVS as switch type when installing the
self-hosted engine?

Hello Devin,
Thanks a lot for this. I was setting up a cluster and intended it enable OVN in
it. I came across this thread when searching for a solution.

We are creating a self-hosted engine deployment and have come up with a draft
design. I thought I'll get your thoughts on improving it. It is still a test
setup and so we can make changes to make it resilient.
We have four hosts, host01..04. I did the self-hosted engine deployment on the

Hello,
We are currently using oVirt version 4.3.10.4-1.0.22.el7. When we click on

I'm creating the VMs from Ansible. The problem is that the "video type" is
defaulting to QXL due to which the VM is failing to start
I've created the below filter. The intention is that it will allow incoming
traffic only from SRCIP parameter and within the port range.
However I'm still able to access the VM from other IPs as well. We are running
oVirt 4.3 and the networks are vlan tagged.

Hello,
I work along with Moiz and here's what we tried.
We created a blank VM, loaded Windows 2016 ISO and booted it up. When we select
the OS as Windows 2016 x64 the ISO is loaded but the screen is stuck with the
windows logo. The CPU spikes up to 99%.
However if we select the OS as 'Other
Good people of the community,
Hope you are all doing well. We are exploring the network filters in oVirt to
check if we can implement a zero-trust model at the network level. The
intention is to have a filter which takes two parameters, IP and PORT. After
that there will be a 'deny all' rule.

Thanks a lot for that. If there's any doc that hints on how to define the
Hello team,
Thank you for all the wonderful work you've been doing. I'm starting out new
with oVirt and OVN. So please excuse me if the questions are too naive.
We intend to do a POC to check if we can migrate VMs off our current VMware to
oVirt. The intention is to migrate the VMs with the

Thanks for that. It is clear now. We have an existing oVirt setup with logical

Hello all,
We are running oVirt 4.3.10.4-1.0.22.el7. I noticed an interesting issue or a
possible bug yesterday. I was trying to add a host when I noticed that it was
failing and the host status was going into 'unassigned' state.
I saw the below error in the engine log.
Hello,
I have a a oVirt 4.3 installation with two clusters. One of the cluster has
switch type as OVS. I'm trying to add a second host to this cluster. I did a
clean install of the OS, configured bond0 and bond0.2306 as the VLAN interface.
I was able to add the host to the cluster.

Hi Sandro,
Thanks for that. I remember you mentioned this in another post too :) I posted
about this as there might be some users using 4.3 and might pitch in with some
ideas. We're starting out with a greenfield setup. Would you suggest that we
rather go with 4.4 directly?
Regards,
Ravi
> I would suggest to rather go with 4.5 directly.
Thanks. I'm afraid we may not be able to go with 4.5 yet as we're going with
Oracle.
Regards,
Ravi

What's surprising is we're seeing the same issue in 4.4.8 as well. Sadly even
this is also EOL now.

Hello all,
I'm facing a strange error. I was able to add a host to a linux bridge based
cluster. However if I try adding the host to a cluster with OVS switch it is
failing. I can see that nmstate was able to create the ovirtmgmt bridge as
well. At that point of time both the ovirtmgmt and the

I tried searching the archives but couldn't find anything related, so posting a

Thank you very much for listing down the steps. It's been 5 years. So I'm not
sure if we still need to create LRPs and LSPs manually? I ask because I do not
see any provision in the oVirt interface.

add the LRPs and

Hope you are all doing well. We have an interesting thing going on and so

We configured a cluster with OVS switch and added an external network with
