Public bug reported:

The following tests fail on Fedora 22 because ssh-keygen output changed
in OpenSSH 6.8:

* nova.tests.unit.api.ec2.test_cloud.CloudTestCase.test_import_key_pair
* nova.tests.unit.compute.test_keypairs.ImportKeypairTestCase.test_success_ssh

Before OpenSSH used MD5 and hex with colons to display a fingerprint. It
now uses SHA256 encoded to base64:

"""
 * Add FingerprintHash option to ssh(1) and sshd(8), and equivalent
   command-line flags to the other tools to control algorithm used
   for key fingerprints. The default changes from MD5 to SHA256 and
   format from hex to base64.
