  22 |test purpose  | To evaluate the IaaS KVM virtualization capability with      |
  23 |              | regards to min, avg and max latency.                         |
  24 |              | The purpose is also to be able to spot trends. Test results, |

  44 |applicability | This test case is mainly for kvm4nfv project CI verify.      |
  45 |              | Upgrade host linux kernel, boot a gust vm update it's linux  |
  46 |              | kernel, and then run the cyclictest to test the new kernel   |
