Hi Nicholas,

Sorry for the late response on this. What version of Eucalyptus are you using?
I just created an EMI from the starcluster iso that boots and that I can ssh
into without modifying the image. I'm using Eucalyptus 1.6.2.

What's weird to me is that I can ssh in, however, I cannot access ip within the instance which means the ec2-get-credentials
file can not be running successfully at startup. Something else must be
configuring the authorized_keys file for root. This is why I wonder if
something's up with eucalyptus on your end? Are you sure your keypair setting
is correct when calling euca-run-instances?

In any event, the exact file that fetches the credentials is in

If you still want to try manually editing this file, you need to change line
11 of this file to:

public_key_url = http://<ip-address>:8773/latest/meta-data/public-

Replace ip-address with your Eucalyptus cloud controller ip.

Let me know if that helps,
