What kind of operation is needed to achieve this effect?

You can attach VMs to a host network on layer 2 by attaching the vNIC to
the vNIC profile of the host network,
e.g. ovirtmgmt/ovirtmgmt. oVirt provides only very little help in IP
configuration of the VMs,
the VM can use the DHCP server of the host network or static IPs.

Looks like the
/etc/ovirt-provider-ovn/conf.d/10-setup-ovirt-provider-ovn.conf does not
fit to engine's expectations.
This can be fixed like described in

[wangyu13476969128]

What is the auth host name and the provider url of the ovirt-provider-ovn
in engine?

The provider url of ovirt-provider-ovn  in engine is :
https://ovirt-manager:9696/

When I  access  https://ovirt-manager:9696/ , it show :
{
  "error": {
"message": "Error during SSO authentication invalid_grant : The provided 
authorization grant for the auth code has expired.",
"code": 401,
"title": "Unauthorized"
  }
}

The hostname of  ovirt-engine  is  "ovirt-manager"

What I hope to do is that the two NICs of the virtual machine are on the same 
network segment as the two NICs on the node. For example, the two IPs on node 
are 172.16.100.10 and 172.16.131.20 respectively. I hope the effect is  the IP 
of the virtual machine on node is also 172.16.100.* and 172.16.131.*

I check the status of  ovirt-provider-ovn.  It's inactive.

Then I start ovirt-provider-ovn  service.

This way the network would be available only for VMs, invisible (in a
GENEVE tunnel)
on the physical network.

This message means that ovirt-engine fails to communicate with
ovirt-provider-ovn.
What is the auth host name and the provider url of the ovirt-provider-ovn
in engine?
Is the ovirt-provider-ovn running on engine's host
(systemctl status ovirt-provider-ovn)?

Unfortunately I am not sure if I understood what the problem is.
Is it still related to aggregated physical interfaces to a bond?

[ovirt-users]Re: Can ovirt-node support multiple network cards ？

[wangyu13476969128]

When I create a new logical network , the option is : 
Select the "Create on external provider" check box, the External Provider is  
"ovirt-provider-ovn".
Leaving Connect to physical network unselected.

The IP of  another network card in node2  is 172.16.91.197.

So the Subnet interface :
CIDR : 172.16.90.0/23
Gateway :  172.16.90.1

Then I click "OK".
The error  show :
Error while executing action AddNetworkWithSubnetOnProvider: Failed to 
communicate with the external provider, see log for additional details.

How can I solve this problem ?

[jeremy_tourville]

I am unable to tell from your question what research you have done or what you 
have tried so far.  Anyway, review this- 
https://ovirt.org/documentation/admin-guide/chap-Logical_Networks.html.  
Generally speaking, the checkbox for "Connect to physical network" should not 
be needed for your example.  You most likely will need to set up VLANs when you 
create the logical network.

[ovirt-users]Re: Can ovirt-node support multiple network cards ？

[wangyu13476969128]

At present, there is a ovirt-node1, which has two physical network cards. The 
IP of one network card is 172.16.91.10, and the IP of one network card is 
172.16.131.10. If I want to create a logical network card, both logical network 
cards are on the same network as the physical network card. For example:
The IP of a logical network card is 172.16.91.11, and the IP of a logical 
network card is 172.16.131.11.

Should I choose "Connect to physical network" in the Logical Network to meet 
the above requirements?

Yes but you either need to create another network in ovirt or bond
interfaces
