  To: dts; +Cc: Ling Wei

v1:
Add virtio smoke test suite sync with test plan.

v2:
1.Modiry Copyrint(c)<2019> to Copyrint(c)<2021>.
2.Fix CentOS check hugepagesize return ' 2048' dts issue.
3.Add test case run exception handing 'kill dpdk-testpmd'
  in set_up and tear_down.

v3:
Modify patch subject and comments description error.

v4:
Modify set_up method,kill testpmd then remove vhost-net*.

v5:
Fix patch spelling error.
