libvirt-python остановил установку devstack, используя stack.sh под Ubuntu 12.04

Я пытаюсь установить devstack под Ubuntu 12.04, используя stack.sh, но я застрял в этой ошибке. Текущая версия Python - 2.7.3

Следовал стандартному методу процедуры установки devstack (единый компьютер), начиная с sudo apt-get update. Дайте мне знать, если потребуется дополнительная информация.
