Trying to build CentOS 6 qcow2 image with OpenStack guide[http://docs.openstack.org/image-guide/content/centos-image.html].
I'm using "cloud-init" instead of the "/etc/rc.d/rc.local" script but I assume "cloud-init" overrides the script?
I successfully created the image, uploaded and created the instance. But can't ssh into it. I suspect that the instance is not pulling ssh public key from the OpenStack server/controller.
[UPDATE: Trying an alternative method by allowing ssh by password]
These are the logs I get from OpenStack admin page.

My instance doesn't boot with my edited "cloud.cfg" Do I need to put them in separate files? Would this enable "ssh centos@ip-address" with password of "centos" ?
Doesn't seem like my question is related to Can't ssh into Centos vm in Openstack

OpenStack qcow config files are very picky. Syntax have to be in exact format. (Spacing, etc).
[/etc/cloud/cloud.cfg]
[/boot/grub/menu.lst - WORKED]
[BAM]
