PXE Server
PXE Server (netboot.xyz)
Network-boot install server. Runs in LXC 702 on pmdell at 192.168.70.2
(migrated from nanofleet LXC 101).
Stack
| Component | Role |
|---|---|
| dnsmasq | proxyDHCP (dhcp-range=192.168.68.0,proxy) + TFTP (:69), serves the iPXE bootloader |
nginx (:80) |
serves the iPXE menus + large assets (ISOs, kernels) from /var/www/html |
| iPXE menus | boot.cfg, menu.ipxe, per-OS *.ipxe, and a Custom URL Menu (custom/custom.ipxe) |
Because the proxyDHCP scope is the whole 192.168.68.0/22, any machine on the
LAN that network-boots gets served — pointed at 192.168.70.2 for TFTP/HTTP.
Custom menu
custom/custom.ipxe (the “fleet menu”) reimages the bbd-vm boxes via Debian
preseed, plus a Proxmox VE 9.2 interactive installer entry
(custom/proxmox.ipxe).
Proxmox installer over PXE
Tip
Plain sanboot of the Proxmox ISO boots the installer but can’t find the ISO
(iPXE’s emulated CD isn’t visible to Linux → “searching for block device…”).
The working method uses proxmox-auto-install-assistant prepare-iso --pxe, which
produces vmlinuz + initrd.img and loads the whole ISO into RAM as a second
initrd (initrd <iso> proxmox.iso) — so both automated and interactive
(TUI/GUI) installers find their source. Needs ≥8G RAM on the target.
Served from 192.168.70.2:
assets/pve-auto/{vmlinuz, initrd.img, proxmox-ve_9.2-1-auto-from-iso.iso} +
custom/proxmox.ipxe.
