This fix works for me flawlessly. One question, shouldn't this be a default behavior for RHEL 7? Without adding TEST_SSHD_USEDNS_NO=True performance of rhel 7 VM is terrible.

I think we need to add some sort of item to our config.json which will allow to specify environment variables for each image e.g.

    {
      "name": "rhel-7",
      ...
      "env": {
         "TEST_SSHD_USEDNS_NO": "True"
      }

we need something like this for el6 as well to set the ssh cipher parameters, which we definitely only want to set for el6:

    {
      "name": "rhel-6",
      ...
      "env": {
         "TEST_EXTRA_SSH_ARGS": "-o PubkeyAcceptedKeyTypes=+ssh-rsa"
      }
