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:
./download-images.sh
Download or check selected targets:
./download-images.sh debian13
./download-images.sh almalinux10
./download-images.sh fedora44
./download-images.sh ubuntu2604
./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:
./download-images.sh --print-path debian13
./download-images.sh --print-path almalinux10
./download-images.sh --print-path fedora44
./download-images.sh --print-path ubuntu2604
./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, UBUNTU_IMAGE_URL, and VIRTIO_WIN_ISO_URL. Each may
list several mirrors of the same file, separated by whitespace; the Fedora
image defaults to the TUNA, BFSU and NJU mirrors, and the Ubuntu image to the
TUNA, NJU and official cloud-images.ubuntu.com mirrors.
When aria2 is installed (aria2c), an image is
downloaded from all of its mirrors at once, with a single connection to each
mirror. Without it, curl (or wget) tries the mirrors in order. A partial
download is only resumed with the same downloader and mirror list; otherwise
it starts over. The Fedora and Ubuntu checksums can be overridden with
FEDORA_IMAGE_SHA256 and UBUNTU_IMAGE_SHA256 when using a custom image.
