A tool to transform Android Cuttlefish images into QEMU disk images

cvd2img

A tool to transform Android Cuttlefish images into raw disk images that can be used with QEMU (and other VMMs).

Building

Dependencies

• parted headers and libraries (libparted-dev in Debian, parted-devel in Fedora)
• clang headers and libraries (libclang-dev in Debian, clang-devel in Fedora)
• The Rust Toolchain

Generating the executable

With all dependencies in place, it should be as simple as running cargo build. The resulting binary will be in ./target/debug/cvd2img.

Using

Preparing the Cuttlefish Directory

1. Download a cuttlefish image from http://ci.android.com/. If you don't exactly what to download, read this guide.

2. Create a directory and unpack for the cuttlefish images and the CVD tools.

mkdir cuttlefish
cd cuttlefish
unzip ~/Downloads/aosp_cf_x86_64_phone-img*.zip
tar xf ~/Downloads/cvd-host_package.tar.gz

Generating the raw disk images

Go back to the cvd2img build directory and execute it pointing to the directory containing the cuttlefish images expanded above:

./target/debug/cvd2img ~/cuttlefish
