On a fresh Arch install (no desktop environment, no network manager) I added a bridge like this with systemd's networkd service: https://wiki.archlinux.org/index.php/Systemd-networkd#DHCP_with_two_distinct_IP . Then in virt-manager under network adapter I just choose "Specify shared device name" as "Network source" and type in "br0" which is the name I gave my bridge.
This page is unnecessarily complicated it seems to me: https://wiki.archlinux.org/index.php/QEMU#Networking
The Arch wiki page on vfio isn't really about networking in qemu/kvm, but a note could be added to visit the KVM and QEMU pages, and those could then be updated to mention this systemd-networkd example.
