Works for me with OpenStack Havana with kvm and your qcow2 image.

This is a very good decision.

Image logs good to the log output and console seems to wok fine.
Is there a root password setup? Ssh also accepts password login per default.
(My favourite would be a standard password people can login on the
console, but only allow ssh login via ssh keys. ??)

Good.

Good.

Minimal image first, this one looks good.

For people now looking at the new OpenStack Havana release: If you want
to setup your own test cloud ontop of CentOS-6.4, please have a look at

best regards,

P.S.: Will the script to setup this CentOS image also be available to
      allow for many stable/customized versions to show up?
