O problema é devido à baixa versão do "libvirt". Se você atualizar os pacotes do Ubuntu 12.04 de "fiel", o problema será resolvido.

Por padrão, o Ubuntu faz downloads de pacotes "precisos", mas o openstack precisa de alguns arquivos lib de "confiáveis", por exemplo, este "libvirt". Abaixo dos passos resolveu este problema.

sudo -s
apt-get install ubuntu-cloud-keyring
echo "deb http://ubuntu-cloud.archive.canonical.com/ubuntu trusty-updates/juno main" > /etc/apt/sources.list.d/cloudarchive-juno.list
apt-get update
exit

Nota: deb http url pode ser usado de qualquer outro arquivo válido de sites do Ubuntu.

Certifique-se de verificar a versão do libvirt

$ libvirtd --version
libvirtd (libvirt) 1.2.2

A saída deve ser maior que 0.9.11 . O stack.sh parou devido a essa condição de verificação, você pode encontrar o mesmo na consulta.
