1. Create new environment (CentOS)
2. Choose nova-network, flat
3. Choose Sahara
4. Add 1 controller, 1 compute, 1 cinder
5. Start deployment. It was successful
6. Start OSTF tests. Test "Check DNS resolution on compute node" has failed on step 1 "Execute host 8.8.8.8 command from a compute node."

Compute is node-2

Nastya actually not ping failed , failed command is host 8.8.8.8 with message connection timed out; no servers could be reached, could you try to execute those command manually please

[Dmitry Pyzhov (dpyzhov)]

According to Nastya, bug hasn't been seen since that time.
