As the storage and network pages; plan reviewed with Codex.
- The list is grouped by type (bridges, bonds, VLANs, ethernet; a type
the host has none of is left out), three cards a row, with a search
of their names, MACs and networks (table_filter.js, which now takes
any element with data-search as a row); a card per interface: its link
as the kernel reports it (up green, down grey, another state or
unknown told as such, no red card for a link that is merely down),
MAC, MTU, speed when known, the members it reports and the libvirt
networks that use it, linked.
- An interface's page: an Interface card (type, libvirt's own state
where it manages interfaces, link, start mode, MAC, MTU, speed, STP,
networks using it); on a host whose libvirt changes interfaces, a
card per family with how it is addressed and its addresses; the
members of a bridge, bond or VLAN with their link and speed, or that
none is reported; for a bridge, the running VMs' cards on it,
directly or through a network using it, with their tap and MAC,
linked (wvmInterface.get_vms: one domain listing). Not the bridge's
delay: netcf tells it in seconds, the udev backend in hundredths.
Start or Stop in its heading, Delete in its menu, disabled while it
runs, on hosts that can change interfaces only.
- A host whose libvirt only reads interfaces says so once, with that
it does not tell their addresses, instead of "None" on every page.
- The New interface dialog is one form, as the New pool and New
network ones (choice_dialog.js, radio_card.html): Bridge or
Ethernet, a bridge's member from the devices it can take, an
ethernet interface's device from the ones the host does not define
yet, a static address's fields with its choice; a refused interface,
or one libvirt refuses, opens it again with what was entered; a made
one opens its page.
- networks_by_device maps the libvirt networks to their bridges or
interfaces on the page's own connection.
libvirt's udev interface backend (RHEL 9 and later, Debian 12) only reads
interfaces, so the create form and the start, stop and delete buttons
only failed there. The pages ask the host with an invalid definition,
which defines nothing: a backend without define refuses it as not
supported. There they show the interface state and a note instead, and
posts change nothing; the host's devices, needed only by the create
form, are not read. Any other answer keeps the pages as they were.
