- fabrics, VLANs, subnets, IP ranges (dynamic/reserved/static), IPAM with adoption of addresses machines already have; rollcall fabric|vlan|subnet|range|ip - interface layouts (physical/bond/vlan, NICs by selector: boot, name, mac, fastest:N, ib:N) per machine or per tag; deployment allocates addresses and writes cloud-init network-config plus udev name rules (RHEL cloud images boot with net.ifnames=0); release frees them; rollcall layout, rollcall net show|set - region/rack: rollcall rack long-polls its desired state (per-MAC PXE files kept in the database, dnsmasq configuration and host files) and a BMC command queue, caches boot and OS images (kernels/initrds prefetched for TFTP), proxies the node API and tags requests with its name; the region runs an embedded rack controller; install-rack.sh, rollcall-rack.service - dnsmasq configuration generated per rack from the VLANs it serves (split pool for two racks); reload script restarts only on change and restores the last working config if dnsmasq does not come back (drilled in the lab) - web: Network page, per-machine network tab, layout action, tag layout; console: Network page, network section in the machine view, layout action - tests for candidates, plans (default, bond+VLAN, pinned, DHCP fallback), network-config, udev rules and dnsmasq rendering - lab: pve-vbmc address script finds the interface per BMC address Verified in the lab: embedded rack (10.213.77.0/24) and a remote rack controller on a second SDN segment (10.213.78.0/24): enlistment, commissioning, BMC through the rack's queue, image cache, deployment and phone-home through the rack; Debian 13, Ubuntu 24.04 and Rocky 9 with a static boot NIC and with an active-backup bond carrying VLAN 200.
