How to run qemu-kvm unittests with KVM autotest

For a while now, qemu-kvm does contain a unittest suite that can be used to assess the behavior of some KVM subsystems. Ideally, they are supposed to PASS, provided you are running both the latest qemu-kvm and the latest linux Avi's tree. KVM autotest for quite a long time has support for running them in an automated way. It's a good opportunity to put your git branch to unittest, starting from a clean state (KVM autotest will fetch from your git tree, leaving your actual development tree intact and doing things from scratch, and that is less likely to mask problems).

A bit of context on KVM autotest build tests

People usually don't know that KVM autotest has support to build and install KVM for testing purposes, from many different software sources. You can:

  1. Build qemu-kvm from a git repo (most common choice for developers hacking on code)
  2. Install qemu-kvm from an rpm file (people testing a newly built rpm package)
  3. Install qemu-kvm straight from the Red Hat build systems (Koji is the instance of the build system for Fedora, Brew is the same, but for RHEL. With this we can perform quality control on both Fedora and RHEL packages, trying to anticipate breakages before the packages hit users)

For this article, we are going to focus on git based builds. Also, we are focusing on Fedora and RHEL. We'll try to write the article in a pretty generic fashion, you are welcome to improve this with details on how to do the same on your favorite linux distribution.

Before you start

You need to verify that you can actually build qemu-kvm from source, as well as the unittest suite.

  1. Make sure you have the appropriate packages installed. You can read [[the install prerequesite packages (client) section | KVMAutotest-InstallPrerequesitePackagesClient]] for more information.

Step by step procedure

  1. Git clone autotest to a convenient location, say $HOME/Code/autotest. See the download source documentation Please do use git and clone the repo to the location mentioned.

  2. Execute the get_started.py script (see [[the get started documentation | KVMAutotest-RunGetStartedScript]]. If you just want to run unittests, you can safely skip each and every iso download possible, as qemu-kvm will straight boot small kernel images (the unittests) rather than full blown OS installs.

  3. As running unittests is something that's fairly independent of other KVM autotest testing you can do, and it's something people are interested in, we prepared a special control file and a special configuration file for it. On the kvm directory, you can see the files unittests.cfg control.unittests. You only need to edit unittests.cfg.

  4. The file unittests.cfg is a stand alone configuration for running unittests. It is comprised by a build variant and a unittests variant. Edit the file, it'll look like:

    ... bunch of params needed for the kvm autotest preprocessor
# Tests
variants:
    - build:
        type = build
        vms = ''
        start_vm = no
        # Load modules built/installed by the build test?
        load_modules = no
        # Save the results of this build on test.resultsdir?
        save_results = no
        variants:
            - git:
                mode = git
                user_git_repo = git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git
                user_branch = next
                user_lbranch = next
                test_git_repo = git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git

    - unittest:
        type = unittest
        vms = ''
        start_vm = no
        unittest_timeout = 600
        testdev = yes
        extra_params += " -S"
        # In case you want to execute only a subset of the tests defined on the
        # unittests.cfg file on qemu-kvm, uncomment and edit test_list
        #test_list = idt_test hypercall vmexit realmode

only build.git unittest

  5. As you can see above, you have places to specify both the userspace git repo and the unittest git repo. You are then free to replace user_git_repo with your own git repo. It can be a remote git location, or it can simply be the path to a cloned tree inside your development machine.

  6. As of Fedora 15, that ships with gcc 4.6.0, the compilation is more strict, so things such as an unused variable in the code *will* lead to a build failure. You can disable that level of strictness by providing extra configure script options to your qemu-kvm userspace build. Right below the user_git_repo line, you can set the variable extra_configure_options to include --disable-werror. Let's say you also want kvm autotest to fetch from my local tree, /home/lmr/Code/qemu-kvm, master branch, same for the kvm-unit-tests repo. If you make those changes, your build variant will look like:

    - git:
    mode = git
    user_git_repo = /home/lmr/Code/qemu-kvm
    extra_configure_options = --disable-werror
    user_branch = master
    user_lbranch = master
    test_git_repo = /home/lmr/Code/kvm-unit-tests

  7. Now you can just run kvm autotest as usual, you just have to change the main control file (called control with the unittest one control.unittests

    $HOME/Code/autotest/client/bin/autotest $HOME/Code/autotest/client/tests/kvm/control.unittests

  8. The output of a typical unittest execution looks like. Notice that autotest informs you where the logs of each individual unittests are located, so you can check that out as well.
