qcow2-rs's Introduction

qcow2-rs

license license

Library in qcow2-rs is for reading/writing data from qcow2 image, and follows its features:

  • async/await, support multiple io engines, verified on tokio-uring, raw linux sync IO syscall, tokio and io-uring1 with smol2 runtime

  • support both direct IO and buffered IO, for direct IO, it needs async runtime support, such as tokio doesn't allow it.

  • basic read/write function on data file, backing file and compressed image

  • l2 table & refcount block load & store in slice way, and the minimized slice size is block size, and the maximized size is cluster size

  • block device like interface, minimized read/write unit is aligned with block size of the FS qcow2 image

  • cross-platform support, verified on linux(Fedora/ubuntu), freebsd and windows

This project is based on qcow2 implementation from rsd3

Motivation of this project is for supporting ublk-qcow24, but turns out it becomes one generic async qcow2 library. Attributed to Rust async/.await, the lib is well designed & implemented, and easy to extend(add new features, improve, ...)

One utility is included in this project, which can dump qcow2 meta, show any meta related statistics of the image, check image meta integrity & host cluster leak, format qcow2 image and convert between qcow2 and raw.

Example

    use qcow2_rs::qcow2_default_params;
    use qcow2_rs::utils::qcow2_setup_dev_uring;
    use qcow2_rs::helpers::Qcow2IoBuf;

    tokio_uring::start(async move {
        let params = Qcow2DevParams::new(9, None, None, false, false);
        let path = std::path::PathBuf::from("test.qcow2");

        // setup one qcow2 device
        let dev = qcow2_setup_dev_uring(&path, &params).await.unwrap();

        // create one slice like & aligned IO buffer
        let mut buf = Qcow2IoBuf::<u8>::new(4096);

        // read 4096 bytes to `buf` from virt offset 0 of `test.qcow2`
        let _ = dev.read_at(&mut buf, 0).await.unwrap();

        // write 4096 bytes from `buf` to virt offset 4096 of `test.qcow2`
        let _ = dev.write_at(&buf, 4096).await.unwrap();

        // flush meta data lazily, which is done in soft update style
        dev.flush_meta().await.unwrap();
    });

Test

  • for running the built-in test, qemu-img is required, so package of qemu-utils(Debian/Ubuntu) or qemu-img(Fedora, RHEL, ...) needs to be installed

  • built CI covers 'carget test' on both ubuntu and windows
