Thanks, looks like OVN is not configured.
Most easy way is to set the default network provider of the cluster to ovirt-provider-ovn and reinstall the host via oVirt web ui.
Alternatively, the configuration of OVN can be triggered manually like descried in
https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.html#configuring-hosts-for-an-ovn-tunnel-network

This error sounds related to ovn provider networks (it uses an
internal OVS bridge, called br-int). Is this 'internal_servers'
network a network 'created on external provider' ?

If so, I think somehow OVN was not properly configured; please tell us
the configuration state in one of your hosts - the output of:
- ovs-vsctl show
- ovs-vsctl list Open
