IIUC your question, you have various options:
1. GUI
2. SDKs
3. CLI
you need to create network in DC, attach it to cluster, attach to host NIC/s (if you want
it to be
atomic operation, i.e you expect connectivity loss during the operation/s, setupnetworks
should be used,
otherwise you can use attach-network dialogues in UI)

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

It looks like you have a bond defined somewhere and it looks like you
have vdsm running on your engine server.
Just looking at my two engine servers and none has more than one ip. The
one in the test setup doesn't even have storage assigned and doesn't
need it. It sends mount commands to the hosts which DO have a separate
storage network. My engine hosts don't host the iso/export domains so
don't need to be in the storage network.
If you have the possibility, go back to a bare machine with
NetworkManager turned off and network turned on. Make sure networking is
working as expected, eth0=ip in managment, eth1= ip in storage.
Install/setup ovirt-engine-setup, don't install vdsm (gets installed if
you do allinone!) and things should 'just' work.

OK, thanks. Then I'm happy with the explanations that it is supposed to work the way I
initially expected..
That all operations are actually carried out on the nodes is good news, and should solve
all worries.
I'll go back and see what is actually going wrong on the engine and try to fix it.
I'd love to reinstall the engine, but as I can't find any documentation on how to
reliably move configs from one engine to another, and I was brave enough to already put
ovirt into production with a number of hypervisors, I'm somewhat limited to what I
can/dare to do.

i think this could be done with puppet, afaik some work for integrating it to
oVirt been done lately, though not sure if it's already available,
oved?
Not sure I understand the use-case, but currently the integration doesn't allow
provisioning of any kind on hosts.
