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.

Hi Michael. So, if I remember coreOS correctly, its the same as all of the cloud based images. It uses SSH keys to authenticate. If you have a an SSH public key in there where you do no longer have the private key for, you can “easily” reset it by 2 ways.
- If its volume based instance, delete the instance but not the volume.
Create the instance again by adding your own ssh key into the boot process. This will ADD the ssh key, but not overwrite the existing one in the authorized_key file 2. If it is normal ephermal disk based instance, make a snapshot and create a new instance from the snapshot, adding your own ssh key into it.
Either or, if they are ssh key authenticated (which they should be), there isn’t really an EASY way unless you want to have the volume directly.
