I am going to be using OVN Geneve overlay networks extensively and I expect a lot of
traffic on the underlay network being used for transmission of the tunnel traffic.
In oVirt the default seems to be that the network "ovirtmgmt" is being used for
the underlay network - which could cause problems for management traffic if vms are
saturating the link with traffic on different OVN overlay networks.
When selecting a specific cluster, selecting "Logical Networks" and pressing the
"Manage Networks" button it is possible to specify that a specific Data Center
Network shall be limited to one or more of the following traffic types:
- VM Network
- Management
- Display Network
- Migration Network
- Gluster Network
- Default Route
Here I miss an option called "Underlay Network for OVN Geneve traffic" or
similar.
Is there a way - e.g. by editing some configuration files on the oVirt engine and on the
oVirt nodes - to divert all overlay Geneve traffic away from the management interface unto
a dedicated network interface?
