With the HVF in-kernel GICv3, QEMU's usb-storage races on the status packet
and Windows Setup stalls 10 s after every burst of reads when installing from
the ISO (utmapp/UTM#7970). Use the emulated interrupt controller until
upstream QEMU gets the fix from the UTM fork. Record the investigation in
windows11-arm64-install-speed.md.

Install it at first logon from the Win32-OpenSSH zip on the seed ISO via
Configure-Windows.ps1 -InstallOpenSSH, replacing the manual 05/06 batch
files. The administrator public key now comes from the host
(SSH_PUBLIC_KEY_FILE or ~/.ssh/id_*.pub) instead of being hardcoded.

Carry the zip for the host architecture in the seed ISO and add
06-Install-OpenSSH-Zip-Admin.bat, which installs from it instead of
Windows Update. Update vm-images.

Replace ramfb with virtio-gpu-pci at 2048x1280 and install the viogpudo
driver from the VirtIO ISO. ramfb has a fixed mode, and keeping both
adapters left Windows with a second, fixed-mode monitor.
Windows Setup and the base image have no viogpudo driver, so on the
launch that creates the system disk the launcher also adds a ramfb ahead
of the config files. The display window shows the first GPU.

The silent installer skips the desktop shortcut option, so the script
creates the shortcut itself.

--install-from-img now works like --install-from-iso: the installation
media is the ISO path (WIN11_VM_INSTALL_ISO or the downloader's) with
.install.img in place of .iso, which is where
build-windows-install-disk.sh writes it by default. Drop the FILE argument
and WIN11_VM_INSTALL_IMG.

On Arm64 Windows the VirtIO guest tools installer is an x86 program and the
VirtIO ISO has no Arm64 package for it, so the first-logon script failed there
and the guest had no network (no NetKVM driver). Install the Arm64 NetKVM,
vioserial, Balloon, viorng and vioinput drivers from their folders on the ISO
with pnputil instead.
The OpenSSH Server capability is downloaded through Windows Update, which can
take very long and blocked the rest of the script. Move it, with the
administrator authorized key, into 05-Install-OpenSSH-Admin.bat, which the
script copies to the Installers folder on the desktop to run by hand.
Update the vm-images submodule to the build script that runs on Debian.

Reading the installation files through QEMU's emulated USB CD-ROM runs at a
few MB/s on macOS. --install-from-img FILE (or WIN11_VM_INSTALL_IMG) attaches
an installation disk image built by vm-images/build-windows-install-disk.sh as
an NVMe disk instead, which is read about 15 times faster. The image is
attached with snapshot=on because NVMe cannot report write protection and
Windows fails on a read-only volume.
Add windows11-arm64-install-speed.md with the analysis and measurements.

Replace qemu/<guest>-<arch>.ini with qemu/<guest>-<os>-<arch>.ini, where os is
linux or darwin, the name platform.system() reports. The accelerators move out
of the shared <guest>.ini into these files (KVM on Linux, HVF on macOS, TCG as
the fallback). The launchers pick the file from the host system and
architecture, and reject amd64 guests on macOS hosts, so no darwin-amd64 files
exist.

Pick qemu-system-aarch64, the AArch64 UEFI firmware and a per-architecture
QEMU config (NVMe disk, virtio-net, ramfb, USB installation media) on arm64,
render the answer file for the target architecture, and move the q35-only
disk and NIC devices out of the shared config. Update vm-images to match
arm64 Windows ISO names.

Move the QEMU hardware definition of the Windows 11 VM into
qemu/windows11.ini and qemu/windows11-amd64.ini, loaded with -readconfig
like the Linux launchers. The network stays in the launcher because a
config file section cannot hold two hostfwd entries. Add --rdp-port and
--ssh-port, which override the WIN11_VM_*_PORT environment variables.
WIN11_VM_MEMORY and WIN11_VM_CPUS are replaced by the config file.

Relaunch as Administrator through UAC when needed, report success or
failure, and wait for Enter before the window closes. Autounattend.xml
passes -NoPause so the unattended install does not block.

Add -InstallVirtIO and -EnableAutomaticLogon switches to
Configure-Windows.ps1 so it can run standalone on a physical machine.
Autounattend.xml passes both switches during the virtual machine install.

Add run-ubuntu2604.py with its QEMU config files and NoCloud seed. The
launcher follows the Debian 13 one, with UBUNTU_VM_ settings and SSH
forwarded to host port 2225. The seed injects the current user's SSH public
key, uses the USTC mirror (ubuntu-ports on arm64) and installs the GNOME
desktop on first boot. Update vm-images for the ubuntu2604 image target.

Moving the SSH port forward into the QEMU config files dropped the
launchers' SSH hint. Read the host port forwarded to guest port 22 from
the rendered config and print the matching ssh command.

user-data is now a template with an @SSH_PUBKEY@ placeholder that
build-seed.sh fills in from SSH_PUBKEY_FILE, ~/.ssh/id_*.pub or ssh-agent.

A [netdev] in a -readconfig file does not stop QEMU from adding its
default NIC, so the guests had a second user-mode network without the
SSH port forward. Both NICs got 10.0.2.15 over DHCP, and SSH only worked
on boots where the forwarded NIC won the race for the default route.
Removing the default NIC shifts the other PCI devices down one slot, so
existing VMs may need their UEFI variable store reset to boot again.

The option downloads the media a launcher would fetch automatically and
exits without checking for QEMU, creating a VM disk or starting the VM:
the base image for Debian, AlmaLinux and Fedora, and the VirtIO tools
ISO for Windows 11.

Apply the Debian launcher's config file layout to Fedora: the shared
qemu/fedora44.ini and qemu/fedora44-<arch>.ini replace the inline QEMU
arguments and the FEDORA_VM_MEMORY, FEDORA_VM_CPUS and
FEDORA_VM_SSH_PORT variables; FEDORA_VM_QEMU_CONFIG selects a different
shared config file.

Move the Debian launcher's QEMU arguments into qemu/debian13.ini, which
the launcher renders with the per-run file paths and passes to QEMU with
-readconfig, followed by qemu/debian13-<arch>.ini for the machine type
and arm64-only devices. Memory, CPU count, SSH port and accelerator are
now set in the config files, replacing VM_MEMORY, VM_CPUS and
VM_SSH_PORT; VM_QEMU_CONFIG selects a different shared config file.

Let each run-*.py launcher take the VM directory (disk, seed ISO, UEFI
variables, PID file, console log) from the command line, taking
precedence over the *_STATE_DIR environment variable. Paths derived
from the state directory are now computed after argument parsing.
