Agreed. Unfortunately, the hosting company (Hetzner) providing the server requires the /29 to be on the host.

Googling "ovirt Hetzner" shows that a number of people have attempted this at Hetzner and have run into various problems. Here is one of the more relevant examples:

So it seems this is doable, but needs a bit more finesse than I've used so far.
