OK. Maybe I'm asking for something irrelevant, but to answer Ren=C3=A9's qu=
estion; The use case is that there are two separate physical networks for g=
eneral IP and storage IP, and Engine seems to require to be able to reach t=
he NFS server to validate the connection when configuring mapping. So to be=
able to configure a NFS server, the Engine needs to be connected also to t=
he storage network.=20
It worked fine after manually tweaking the sysconfig/network-scripts, but t=
his config was then shortly overridden by Engine discovering and trying to =
use the second NIC for bonding with ovirtmgmt.=20

IIUC your question, you have various options:=20

you need to create network in DC, attach it to cluster, attach to host NI=
