docs: proxmox:// bootstrap metal-validated + QGA finding#111
Merged
Conversation
Metal-validated the proxmox:// bootstrap on the homelab (2026-07-07): with a static IP, install --target proxmox://homelab?...&ip=... created the VM, applied the static IP, waited for SSH, and deployed the cross-built Linux controller -- systemd openctl-controller.service came up active with :9444 (gRPC) + :9445 (UI) listening. Flip [~] -> [x]. Prereq documented: make build-controller-linux (the installer expects a pre-built bin/openctl-controller-linux-amd64). Known limitation found: DHCP mode times out on IP discovery because the QGA-install cicustom snippet silently no-ops on local-lvm (LVM storages cannot hold snippets content), so qemu-guest-agent never installs and the DHCP IP is undiscoverable. Static ip=... bypasses QGA. Added a follow-up roadmap item to harden the QGA-install path (cloud-init packages, or auto-pick a snippets storage, or fail loudly instead of a 10m timeout).

With a static IP,

DHCP mode times out on IP discovery: it relies on the qemu-guest-agent, but the QGA-install
cicustomsnippet silently no-ops onlocal-lvm(LVM storages can’t holdsnippetscontent), so QGA never installs and the DHCP IP is undiscoverable. Staticip=…bypasses it. Added a roadmap follow-up to harden the QGA-install path (install QGA via cloud-initpackages, auto-pick a snippets storage, or fail loudly instead of a 10-minute timeout).Docs-only.
