+|test case id | OPNFV_YARDSTICK_TC028_KVM Latency measurements |
+| | |
++--------------+--------------------------------------------------------------+
+|metric | min, avg and max latency |
+| | |
++--------------+--------------------------------------------------------------+
+|test purpose | To evaluate the IaaS KVM virtualization capability with |
+| | regards to min, avg and max latency. |
+| | The purpose is also to be able to spot trends. Test results, |
+| | graphs and similar shall be stored for comparison reasons |
+| | and product evolution understanding between different OPNFV |
+| | versions and/or configurations. |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | file: samples/cyclictest-node-context.yaml |
+| | |
++--------------+--------------------------------------------------------------+
+|test tool | Cyclictest |
+| | |
+| | (Cyclictest is not always part of a Linux distribution, |
+| | hence it needs to be installed. As an example see the |
+| | /yardstick/tools/ directory for how to generate a Linux |
+| | image with cyclictest included.) |
+| | |
++--------------+--------------------------------------------------------------+
+|references | Cyclictest_ |
+| | |
++--------------+--------------------------------------------------------------+
+|applicability | This test case is mainly for kvm4nfv project CI verify. |
+| | Upgrade host linux kernel, boot a gust vm update it's linux |
+| | kernel, and then run the cyclictest to test the new kernel |
+| | is work well. |
+| | |
++--------------+--------------------------------------------------------------+
+|pre-test | The test kernel rpm, test sequence scripts and test guest |
+|conditions | image need put the right folders as specified in the test |
+| | case yaml file. |
+| | The test guest image needs with cyclictest included in it. |
+| | |
+| | No POD specific requirements have been identified. |
+| | |
++--------------+--------------------------------------------------------------+
+|test sequence | description and expected result |
+| | |
++--------------+--------------------------------------------------------------+
+|step 1 | The host and guest os kernel is upgraded. Cyclictest is |
+| | invoked and logs are produced and stored. |
+| | |
+| | Result: Logs are stored. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | Fails only if SLA is not passed, or if there is a test case |
+| | execution problem. |
+| | |
