-### Test Profiles
-
-The integration tests support two test profiles:
-- **devel**: this is the recommended profile for running the integration tests
-  on a local development machine.
-- **ci** (default option): this is the profile used when running the
-  integration tests as part of the the Continuous Integration (CI).
-
-The test profiles are applicable to tests that run using pytest. Currently only
-the [coverage test](tests/test_coverage.py) follows this model as all the other
-integration tests are run using the
-[Buildkite pipeline](https://buildkite.com/rust-vmm/vm-virtio-ci).
-
-The difference between is declaring tests as passed or failed:
-- with the **devel** profile the coverage test passes if the current coverage
-  is equal or higher than the upstream coverage value. In case the current
-  coverage is higher, the coverage file is updated to the new coverage value.
-- with the **ci** profile the coverage test passes only if the current coverage
-  is equal to the upstream coverage value.
-
-Further details about the coverage test can be found in the
-[Adaptive Coverage](#adaptive-coverage) section.
-
-### Adaptive Coverage
-
-The line coverage is saved in [tests/coverage](tests/coverage). To update the
-coverage before submitting a PR, run the coverage test:
-
-```bash
-docker run -it \
-           --security-opt seccomp=unconfined \
-           --volume $(pwd):/linux-loader \
-           rustvmm/dev:v2
-cd linux-loader/
-pytest --profile=devel tests/test_coverage.py
-```
-
-If the PR coverage is higher than the upstream coverage, the coverage file
-needs to be manually added to the commit before submitting the PR:
-
-```bash
-git add tests/coverage
-```
-
-Failing to do so will generate a fail on the CI pipeline when publishing the
-PR.
-
-**NOTE:** The coverage file is only updated in the `devel` test profile. In
-the `ci` profile the coverage test will fail if the current coverage is higher
-than the coverage reported in [tests/coverage](tests/coverage).

 ### bzImage test
 
 As we don't want to distribute an entire kernel bzImage, the `load_bzImage` test is ignored by
