The known-gaps entry, decision log, sample comment and builder comment
blamed the host; the cause is trixie's GRUB config ("terminal_output
gfxterm serial" with a serial console and no video device), reported
and reproduced upstream and still open. UEFI remains the default for the
reason recorded; bookworm images are noted as unaffected.

Run 5 on the real host bisected the guest hang: the Debian 13 image
hangs after GRUB under SeaBIOS with or without our seed and with either
CPU model, and boots under OVMF. The image's legacy boot chain is the
problem, not the provider.
images.<key>.firmware is "uefi" (default) or "bios". The domain XML
emits <os firmware="efi"> with secure boot off, so libvirt selects the
OVMF binary and manages the NVRAM file, which the existing nvram undefine
flag removes. Direct-URL images default to UEFI too. OVMF joins the
hypervisor prerequisites; sample, config table, known gaps, decision log
and the execution log record the finding.

The first run against a real hypervisor (beelink, Ubuntu, libvirt 11.6)
failed at DomainCreate with "Could not open base image: Permission denied"
even with correct DAC ownership. libvirt's virt-aa-helper only grants QEMU
access to disk sources that carry a path; the <disk type="volume"> form
chosen in Step 2 gives it pool and volume names instead, so the overlay and
its backing image get no AppArmor rule on any stock Debian/Ubuntu host.
buildDomainXML now takes DiskPath/SeedPath and emits type="file" disks.
ensureOverlay and writeSeed return the volume handles and Create resolves
both paths with StorageVolGetPath before defining the domain. The domain
XML test rejects any volume/pool reference so this cannot drift back; the
Create test asserts the sources equal the paths libvirt reported.
Execution log: Step 2 note marked reverted, Step 7 entry opened with the
two failed runs and the diagnosis.

Introduces internal/provider/kvm with the side-effect-free pieces of the
provider: providerID format/parse, the namespaced <metadata> element that
carries the GC contract, q35 domain XML over pool volumes, volume XML for
overlays and raw seeds, the NoCloud seed ISO built with kdomanski/iso9660,
and config defaults. All unit-tested.
Step 2 of docs/plans/2026-09-04-1404-kvm-provider.md.
