Avocado VT Plugin

Avocado Virt Test Compatibility is a plugin that lets you execute virtualization related tests, with all conveniences provided by avocado.

Getting started with avocado-vt

Here's a reference guide on how to get the plugin setup and running, assuming you are using git repos for avocado and avocado-vt. Please keep in mind that the recommended way of using avocado is through RPM packages, that you can see how to install in our online documentation:

http://avocado-vt.readthedocs.org/en/latest/GetStartedGuide.html

If you want to go ahead and use the git repos (you're hacking on avocado and avocado-vt), then follow the instructions below:

1. Make sure you have avocado and avocado-vt repositories cloned in the same dir. then you can execute our make link target:

   $ make link
   

2. Avocado-VT has a number of dependencies on other software packages. You can install those dependencies via pip, or some other method of your preference (install distro packages, for example). As an example, on a recent Fedora install (> 22), the dependencies can be installed with:

   $ yum install autotest-framework p7zip tcpdump iproute iputils gcc glibc-headers python-devel nc aexpect
   

   This assumes you are using our software repositories to install packages such as aexpect (see the GetStartedGuide.html link above). If you use other distros, we trust you'll take the above as a reference and will find the correspondent software packages to install. For example, you can install autotest-framework and aexpect using pip:

   $ pip install autotest aexpect
   

   Keep in mind that this text file might be outdated, and that usually our spec file (avocado-plugins-vt.spec) tends to be a good reference as well.

3. Run the bootstrap procedure for the test backend (qemu, libvirt, v2v, openvswitch, among others) of your interest. We'll use qemu as an example:

   $ scripts/avocado vt-bootstrap --vt-type qemu
   

   That command will generate the following symlinks in your avocado source code dir (assuming you have only avocado-vt, and not avocado-virt):

   avocado/core/plugins/virt_test.py
   avocado/core/plugins/virt_test_list.py
   etc/avocado/conf.d/virt-test.conf
   virttest
   

   Also, it's important to note that this process will create a new directory in your home dir, by default, ~/avocado. This directory will be populated with a number of config files (and other data files) necessary to run the avocado-vt tests.

4. Let's test if things went well by listing the avocado plugins. In the avocado source dir, do:

   $ scripts/avocado plugins
   

   That command should show the loaded plugins, and hopefully no errors. The relevant lines will be:

   virt_test_compat_bootstrap  Implements the avocado 'vt-bootstrap' subcommand
   virt_test_compat_runner  Implements the avocado virt test options
   virt_test_compat_lister  Implements the avocado virt test options
   

5. The next test is to see if virt-tests are also listed in the output of the command avocado list:

   $ scripts/avocado list --verbose
   

   This should list a large amount of tests (over 1900 virt related tests):

   ACCESS_DENIED: 0
   BROKEN_SYMLINK: 0
   BUGGY: 0
   INSTRUMENTED: 52
   MISSING: 0
   NOT_A_TEST: 27
   SIMPLE: 3
   VT: 1923
   

6. Assuming all is well, you can try running one virt-test:

   $ scripts/avocado run type_specific.io-github-autotest-qemu.migrate.default.tcp
   JOB ID     : <id>
   JOB LOG    : /home/<user>/avocado/job-results/job-2015-06-15T19.46-1c3da89/job.log
   JOB HTML   : /home/<user>/avocado/job-results/job-2015-06-15T19.46-1c3da89/html/results.html
   TESTS      : 1
   (1/1) type_specific.io-github-autotest-qemu.migrate.default.tcp: PASS (95.76 s)
   PASS       : 1
   ERROR      : 0
   FAIL       : 0
   SKIP       : 0
   WARN       : 0
   INTERRUPT  : 0
   TIME       : 95.76 s
   

If you have trouble executing the steps provided in this guide, you have a few options:

• Send an e-mail to the avocado mailing list.
• Open an issue on the avocado-vt github area.
• We also hang out on IRC (irc.oftc.net, #avocado).
