Hi

Couple of questions around macvtap direct usage:

1) is the document here current?
https://libvirt.org/formatnetwork.html#examplesDirect

I have been able to get host to guest network traffic without any special
configuration or switch since Fedora 28 when I first started using it.
Using <forward mode=vepa> requires switch port mirroring, but just using
<forward mode=bridge> doesn't.

2) do any of the language libraries make assumptions that libvirt networks
must have a <bridge name=xx> attribute? Foreman's Ruby interface to libvirt
errors out with attempting to build a VM on a KVM host with a network
defined with <forward mode=bridge>
https://projects.theforeman.org/issues/25890

thanks
Subhendu
