The Windows image is quite large (about 20GiB), hence it takes some time to copy it for every test in order to avoid potential corruption. One way to mitigate that without compromising on safety between each test is by using device mapper. By creating a read-only base, we ensure the image won't be modified by any of the tests, and by creating one snapshot for each test, we avoid copying the entire image each time. A dedicated Copy On Write disk image is created to handle any change that might be performed on the base image, letting the tests behave as expected.
