Manual scripts

resources/scripts/ holds standalone host- and guest-side scripts. vmw does not run these automatically; run each one by hand when its situation applies. resources/scripts/Linux/SMBIOS.py is the one exception — steps/qemu.py calls it directly to build smbios.bin.

Linux (host side)

vbios-dumper.sh

Dumps the GPU's video BIOS from sysfs: unbinds the current driver, enables the ROM read at /sys/bus/pci/devices/<BDF>/rom, copies it out, disables the ROM read, and rebinds the driver. The PCI address is hardcoded to 0000:01:00.0 at the top of the script — edit it to match your GPU (lspci shows the address). The dumped .rom file is what a passthrough profile points to when a card needs a vBIOS to avoid Code 43.

vbios-dumper-safe.sh

Same purpose as vbios-dumper.sh, hardened for laptop GPUs, which can hang on an unbind or a ROM read. It adds timeouts on both steps, checks the dump size before accepting it, rebinds the driver on any failure, and prints the file's first bytes so you can confirm the dump is a real VBIOS and not empty or truncated. Prefer this version on a laptop; use vbios-dumper.sh on a desktop where the plain version is faster.

evdev-auto.sh

Detects physical keyboard and mouse devices under /dev/input/by-id/ and /dev/input/by-path/, deduplicates them by real path, and prints a libvirt <input type="evdev"> block for each — for a single-GPU passthrough setup that switches keyboard and mouse into the guest with a hotkey (shift-shift by default). Paste the output into the domain XML's <devices> section.

arch_kernel_downgrade.sh

Installs Linux 6.10.arch1-2 and its headers from the Arch Linux Archive, pins the kernel package in pacman.conf with IgnorePkg so a routine pacman -Syu does not upgrade past it, rebuilds the initramfs, and reboots. Use this to roll back to a known-good kernel version when a newer one regresses a build or breaks guest boot. Edit the package version at the top of the script to target a different kernel release.

Windows (guest side)

EDID_OVERRIDE.ps1

Run as Administrator inside the guest. Reads each connected monitor's real EDID over WMI, zeroes the manufacturer serial-number field and any monitor-serial-number descriptor block, recomputes the EDID checksum, and writes the modified EDID into that monitor's EDID_OVERRIDE registry key. Restarts the display drivers so Windows picks up the new EDID immediately.

qemu-cleanup.ps1

Run inside the guest. Downloads Sysinternals PSTools if not already present, then uses PsExec to run a cleanup step as SYSTEM that scans HKLM\SYSTEM\CurrentControlSet\Enum for device entries matching VirtIO PCI identifiers (VEN_1AF4, DEV_1B36, SUBSYS_11001AF4) and deletes them, and removes every subkey under Enum\SCSI. Use this after removing or replacing a VirtIO device, so Windows' device history does not keep an entry for hardware that is no longer present — a stale entry there is a difference from a physical machine that a careful check could otherwise read.
