Trying to assign ovirtmgmt to network bond on host causes immediate loss of connectivity

Hi, we have set up OLVM v. Version 4.5.4-1.0.27.el8 on a server (running Oracle Linux 8 fully updated) and are trying to add our first KVM host, 'ovs25' (running Oracle Linux 8, fully updated).

The network is using VLAN segmenting and connectivity is done on VLAN 112.

The ovs25 host machine has two ethernet NICs. In order to give the ovs25 connectivity, we used NetworkManager to create a network bond, 'bond0', which combined the two Ethernet NICs, using this command:

nmcli connection add type bond ifname bond0 con-name bond0  bond.options "mode=802.3ad,miimon=100

nmcli connection modify bond0 ipv4.method disabled ipv6.method ignore
