So there are a couple of things to keep in mind. During engine-setup you
need to say yes for the OVN provider option.
The cluster with the hostat needs to have default network provider, which
for "Default" cluster is configured automatically when the
OVN option is yes. With those conditions you don't need to start any
service, everything should be running and the hosts installed
in the cluster will have tunnels ready on ovirtmgmt.

I am able to power on vms on newly upgraded host, But not able to migrate VMs

Thanks for that. We performed a normal oVirt install and as a part of it the 
controller was installed in the manager. I can see the pre-req rpms and 
services are also installed in the hypervisors. So If I understood correctly 
you're saying that the tunnels and bridge would've been already created when we 
added the host?
If we just bring up the openvswitch and ovn-controller services we should be 
able to see the tunnels and bridge.

I recommend having a look at this solution:
https://lists.ovirt.org/archives/list/users@ovirt.org/message/IMHIBGCFIED32NIOBZCUXIPVAGFNSDJZ/
from this previous discussion:
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/VHVZF6H3VM4ZUK5HRP3HUIC26UBLXWFM/
Let us know if it worked for you.

[ovirt-users] HostedEngine deployment fails

[Christoph Köhler]

Hello,

on CentOS Stream the deployment of HE fails with the following message:


[ INFO  ] TASK [ovirt.ovirt.engine_setup : Gather facts on installed
packages]

[ INFO  ] ok: [localhost -> 192.168.1.239]

'ovirt-4.4-centos-ceph-pacific': Cannot download repomd.xml: Cannot
download repodata/repomd.xml: All mirrors were

It's because we have to use a proxy. It is configured on the host but
setup does not deliver it into the appliance (temporarily HE). So what
to do? Howto tell setup to use a proxy in HE appliance?

Thank you for hits!

Hi Jihwan,
Just making sure, everything is working as expected after the engine-setup
worked?
The ovirt-engine.service, and ovirt-engine-dwhd.service are active ?

Thanks,

You should not run ovn-config manually,  if the host bond0 has ovirtmgmt on
top of it. That is all done by host deploy. The step might be needed if you
want to have a tunnel on a different interface than ovirtmgmt is using.

at

 _dbfunc_common_get_current_version() {

it takes 04040070 so it skip all upgrade script that less then version 04040070.

i don't know why that value in table but when i delete that value 
'engine-setup' works well

We are still in the initial stages and so conducting a POC.

We are planning to clone a VM and then migrate it to note down the findings. We 
will surely verify the virtual nic hw as well.

We have SDN implemented at our physical network level. IIRC it is Cumulus. We 
do not have NSX. What I meant was as we have SDN implemented at the physical 
network level. So will it make it easier to connect our Ovirt to the physical 
network. 
I will go through the docs you updated and come back.

My apologies. I wasn't clear. As the IP was assigned on bond0 which is a LACP 
bond, do we need to make any changes before running the vdsm-tool ovn-config 
  ?

I'll go through the docs you mentioned and update here about my progress.

[ovirt-users] Re: About go-ovirt Library

[Janos Bonic]

Hey Yusuf,

We haven't tagged a new version for go-ovirt recently. Please use go get
github.com/ovirt/go-ovirt@master to get the latest version.

Alternatively, we are currently working on an overlay for go-ovirt that
makes it less painful to use. Please see if you can use it:
https://github.com/ovirt/go-ovirt-client.
