Open Stack

 Our openstack env automatically injects SSH keys) and already does that
with all other images I have downloaded to deployed e.g fedora cloud images
and ceros cloud image.

However core os is different and I have tried to edit grub added
coreos.autologin=tty1
but nothing.

Also tried to do this via cloud-config

#cloud-config

coreos:
    units:
      - name: etcd.service
        command: start

users:
  - name: core
    passwd: coreos
    ssh_authorized_keys:
  - "ssh-rsa xxxxx"


And not luck - when vm boots it hangs.
