Could you explain further why does the host need to do any routing?

Assaf, do you have a guess? Which version of ovirt have you been using? Now, with source-routing implemented into ovirt-3.3, there is a danger in setting your own content into route-<netname>, as it would be overwritten if <netname> is reconfigured via Engine. > > Scenario 2: Dreaming.

Is the "Host did not satisfy internal filter Network" message coming from Hetzner management, or oVirt's? > I even tried removing > ovirtmgmt network and leaving private network by itself.

In my experience, your easiest option is to define a dummy interface ip link add name dummy_private type dummy and set up a normal oVirt network on top of it, as if it were a true nic. > > Either way if you have a minute or two please take a look at both attached > diagrams.
