Description Slawek Kaplonski 2020-11-12 12:19:26 UTC

In the VM boot process, cloud-init copies the SSH keys.

If the tempest test tries to connect to the VM before the SSH keys are copied, the SSH client will raise a paramiko.ssh_exception.AuthenticationException. From this point, even when the SSH keys are copied into the VM, the SSH client cannot reconnect anymore into the VM using the pkey.

If a bigger sleep time is added manually (to avoid this race condition: try to connect when the IP is available in the port but the SSH keys are still not present in the VM), the SSH client connects without any problem.
