I'm not sure of whether or not these things work in the status of these
things in fedora/RHEL.  I suspect that all below is true other than
disk space resize.  However, the following is true for ubuntu:

> - hostname set to instance name

 - hostname is set to whatever is in local-hostname of the metadata
   service. I think that actually does correlate to 'name' in the nova
   launch api.

> - disk space resize to flavor size

 - cloud-init runs resize2fs on the root partition on start up.  However,
   if you have a partition table on the disk, right now, that relies upon
   initramfs code delivered in cloud-initramfs-growroot [1] to grow the
   partition , and tell the kernel to re-read the partition while the
   filesystem is not mounted (otherwise you have to reboot).

   [1] https://launchpad.net/ubuntu/+source/cloud-initramfs-tools

> - ssh-key pull

 - cloud-init does that by default to the default user and adds it to the
   root user's .ssh/authorized_keys, with a message that says "you need to
   login as <the-configured-user>"

> - report a random password for root user (or default user) if this is possible

 - by default, cloud-init does not set a password for a user.  However, it
   can be told to via configuration (cloud-config in the image or passed
   in via userdata).  That looks like:
     password: RANDOM
   or
     chpasswd:
      list: |
        user1:password1
        user2:RANDOM
      expire: True
   There is more info at [2].

Currently I have ssh keys getting imported but having some problems getting the disk to dynamically resize to the flavor template as well as the hostname set in horizon to be pushed into the image. Does anyone have any howtos or suggestions on how to get this done? Is there cloud-init for centos just like ubuntu? I would also be interested in how to do this with debian as well.
