can we please check if this is still valid bug?

[chandan kumar (chkumar246)]

So it was related to old cirros image, now we have updated cirros image to 0.4.0 in tempestconf and here is the tests results from CI.
http://logs.openstack.org/16/662716/2/check/tripleo-ci-centos-7-standalone/4ed6ad1/logs/stestr_results.html -> test_server_basic_ops[compute,id-7fff3fb3-91d8-4fd0-bd7d-0204f1f180ba,network,smoke] -> passed

Closing this bug, still finds the issue, please open it.
