Phase 0. Replace the spoof-hv knob with spoof-mode, a first-class selector modeled as two axes (persona x presence) exposed as 4 presets: - none: stock (spoof_on now requires mode != none, killing half-spoof states) - hyperv: Microsoft Virtual Machine persona + Hyper-V presence (honest child VM) - vbs (seeded default): real-OEM persona + Hyper-V presence (mimic physical Win11+VBS) - physical: real-OEM persona + bare metal Engine: spoof_mode()/spoof_persona_msvm()/spoof_presence_hyperv() in spoof-core; the hv/waet/pvpanic/vmgenid policies now derive from the mode. microsoft-vm persona wired across platform (ACPI OEM VRTUAL/MICROSFT, Microsoft Corporation), system type1 (Virtual Machine), storage (Virtual HD / Msft Virtual DVD-ROM) and EDID (MSF/Hyper-V). New getters spoof_system_manufacturer/product (type1, real-OEM or Hyper-V). Patches: 0002 registers spoof-mode; 0024 now also forces type1 system identity. spoof-hv kept as a back-compat alias. Inert without a seed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

qemu-spoof: SMBIOS type0 BIOS + type1 system identity
|
|
|
|
Stock QEMU leaves type0 vendor/version/date unset (guest reads an empty/firmware-
|
|
default "SeaBIOS" BIOS via WMI/dmidecode) and type1 system manufacturer/product fall
|
|
back to the bare machine values. Force the persona identity through smbios_set_defaults:
|
|
- real-OEM persona: vendor-formatted BIOS + board-brand system manufacturer/product;
|
|
- hyperv persona: Microsoft "Virtual Machine".
|
|
Config (-smbios) still wins; an un-seeded VM stays stock. (spoof.h include added by
|
|
0015-smbios-vm-bit.)
