Comment 1 for bug 1317592

I can also confirm that this affects the Vagrant box located at: http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box

After first boot up running 'sudo sshd -t' generates the error:

    Could not load host key: /etc/ssh/ssh_host_ed25519_key

If `vagrant reload` is run before the key is generated by hand, then the VM will become unresponsive as the SSH daemon will not start. Generating the key manually prior to first reboot works around the issue.
