After upgrading to the latest stable version the external networks lost all functionality. Under providers-->ovn-network-provider the test runs successfully.
But when im creating an external provider network, attaching it to a router as a LAN setting up dhcp lease it is not reachable from other VMs in the same network. Hosts and hosted engine can't seem to ping it either.
I tried disabling firewalls on both hosted engines, VMs and host and still nothing.
When configuring Logical networks or VLANs they work perfectly tje one problem is the external networks.
I have another environment running on a previous version of ovirt and it works perfectly there. I think its a bug.
