[rhos-list] EXTERNAL: Re: SSH Key Injection not working.

[Minton, Rich]

Josh,

I did a lot of reading over the weekend and have a better understanding of how cloud-init works. I thought that the ssk key injection was a onetime thing at first boot and by booting my image to make changes was affecting how cloud-init was working when I launched an image. So I went back and created a master image without cloud-init so that I could make changes to the image as needed and then install cloud-init as the last step before powering down the image. Then I ran "glance image-create" with that image so that when an instance was launched cloud-init would be run for the first time. That didn't seem to matter. Still no keys in "authorized_keys" file for root or "cloud-user". I used Wire shark to watch the traffic to the meta-data server and I can even see the ssh keys coming back to the VM. I just don't see them in the authorized_keys file anywhere.

No today my VMs on a particular host cannot reach the meta-data server. I get "no route to host" errors but it still seems to be getting the hostname and host keys. It fails on "Applying ssh credentials". I included the boot.log and cloud-init.log.

Any help you can provide would be greatly appreciated. I already have grey hair so the next phase would be... I don't even want to mention it.

Thanks,
Rick
