Hello, The problem with ovn ( 'br-int': No such device) occurs because you are missing an ovs bridge named "br-int" on your host. This is the integration bridge used by ovn to create its logical networks. This is normally created by default during ovs/ovn installation. Please try adding this manually: ovs-vsctl add-br br-int You can check if it exists using: ovs-vsctl show Once added the vm should start fine.
The network filters which you can define in ovirt are the libvirt network filters (https://libvirt.org/formatnwfilter.html) Afaik there is not "default" firewall solution advised for ovirt. I will check if there are any good practices described, but I have not seen any so far.
