So it sounds like you think libvirt /should/ be going out and
configuring shared storage. What about VLAN set up on my router
hardware? That too, right?

No - it's exactly the reason for SOME common API. No-one is arguing that
a common API for host networking is a bad idea.

"There isn't an API, and it's sometimes needed for management" is not an
argument for it be part of libvirt's scope.

Again, what makes libvirt a good place for this management? I don't
accept "because it's there" as a reasonable justification...
