Bug Description

When attempting to build an ubuntu image for xen, the script fails with python interpretation errors.

vmbuilder xen ubuntu --help results in the following stack trace:

Traceback (most recent call last):
  File "/usr/bin/vmbuilder", line 24, in <module>
    cli.main()
  File "/usr/lib/python2.6/dist-packages/VMBuilder/contrib/cli.py", line 59, in main
    hypervisor, distro = self.handle_args(optparser, sys.argv[1:])
  File "/usr/lib/python2.6/dist-packages/VMBuilder/contrib/cli.py", line 160, in handle_args
    hypervisor = VMBuilder.get_hypervisor(args[0])(distro)

AttributeError: 'SettingGroup' object has no attribute 'add_option'

Investigation into this issue reveals that the developer likely intended to call the method 'add_setting' in the object SettingGroup. However, fixing this error only results in another one:
