I migrate over the vm network.

You need to ask someone more familiar with Ovirt about the migration vs. the vm network. I have had issue getting different subnets for the vm’s to function properly. My understanding is that if the engine host knows and can use the network, you should be able to use it. However, the migration network has to be setup on the hosts and attached to a nic in order to use it. In the host properties and setup networks, is the migration network attached to a nic with the proper subnets or vlans?

I’m not sure if that’s helpful or not. I just don’t know enough about Ovirt to give a definitive answer.

Thanx for the note.  Still not working.  I made the change on the hosts and manager and then added the custom ip addresses to the ovirtmgmt network.   The attached screenshot shows the custom IP address added to ovirtmgmt.

Same issue.

2020-04-10 21:05:13.882+0000: 5801: error : virNetSocketNewConnectTCP:591 : unable to connect to server at '192.168.25.5:49152': No route to host.

I can ping the 192.168.25.x address on the host - but I can't ping the .25.x address on the other host.

I also can't ping either 192.168.25.x address from the manager.

One question I had is does the migration network need to be a VM Network?  I've tried it several ways - but just wanted to know the right configuration.

Thanx!!!

Thanx for the suggestion.  Changed my networks to the following and still got the same error:

5801: error : virNetSocketNewConnectTCP:591 : unable to connect to server at '192.168.25.5:49152': No route to host

Here is my updated configuration:
- 2 Hosts
- Host 1
- nic 1 - ovirtmgmt - 192.168.1.24/24 - VLAN 1
- nic 2 - migration network - 192.168.25.5/24 VLAN 25
- Host 2
- nic 1 - ovirtmgmnt - 192.168.1.24/24 - VLAN 1
- nic 2 - migration network - 192.168.25.6/24 - VLAN 25

Migration network is setup as follows:
- Assign - Yes
- Required - Yes
- VM Network - No (tried it with VM Nework = Yes with same results)
- Migration Network - Yes
