# vm-images

Shared, locally cached virtual-machine installation media and base images.
Downloaded ISO, QCOW2, IMG, VHD, and VHDX files are intentionally excluded
from Git.

## Download images

Download every supported image:

```bash
./download-images.sh
```

Download or check selected targets:

```bash
./download-images.sh debian13
./download-images.sh almalinux10
./download-images.sh fedora44
./download-images.sh virtio-win
```

The Windows installation ISO is not downloaded because Microsoft's temporary
download URLs expire. Place it manually in `install-iso/`; the script finds it
automatically by matching `Win`, `11`, `x64` and `.iso` in that order
(`*Win*11*x64*.iso`, case-insensitive). If several files match, the highest
version-sorted name is used. Check which file was picked with
`./download-images.sh --print-path windows11 --iso`.

## Query image paths

The path interface prints one absolute path without downloading anything:

```bash
./download-images.sh --print-path debian13
./download-images.sh --print-path almalinux10
./download-images.sh --print-path fedora44
./download-images.sh --print-path virtio-win
./download-images.sh --print-path windows11
./download-images.sh --print-path windows11 --iso
```

The Windows target prints the QCOW2 path by default. Add `--iso` to print its
manually supplied installation ISO path. The QCOW2 is named after the detected
ISO (for example `Win11_25H2_English_x64_v2.iso` →
`base-qcow2/Win11_25H2_English_x64_v2.qcow2`); if no ISO is present, an
existing `*Win*11*x64*.qcow2` in `base-qcow2/` is used instead.

Download URLs can be overridden with `DEBIAN_IMAGE_URL`, `ALMA_IMAGE_URL`,
`FEDORA_IMAGE_URL`, and `VIRTIO_WIN_ISO_URL`. The Fedora checksum can be
overridden with `FEDORA_IMAGE_SHA256` when using a custom image.
