Golang转换并调整qemu-img的大小

Question

I'm trying to convert .iso-image to lvm(https://docs.openstack.org/image-guide/convert-images.html) with golang

func (c *ImageHandler) ConvertTempImageToLVM() error {
    cmd := exec.Command("qemu-img", "convert", c.ImagePath, "-O", "raw", c.LVMPath)

    _, err := cmd.CombinedOutput()
    if err != nil {
        return fmt.Errorf("'qemu-img resize' output: %s", err)
    }
    return err
}

And I didn't find any qemu-libraries in github. Maybe I wrong

I need a solution how can I resize and convert .iso images without using exec.Command()??
