A big limitation of the macvtap approach is that it would let you
connect only a single VM to your WiFi. Is that fine by you?

Yes, defining a libvirt network requires using
virsh net-define <xmlfile>
(you may need to pass the not-so-secret vdsm at ovirt/shibboleth password
to tinker with libvirt, which is better done on non-production setup)
virsh net-dumpxml <net-name>
could show you what's already defined, but I don't expect you to have
interesting networks as of yet.
It may not be easy, but I'd be grateful if you report here on what you
will have accomplished.
