Openstack nova 在Kilo代码版本中，nova在KeyoneClient上启动失败，错误为500

我在CentOS7上安装了KLO rc1，带有以下rpm套件

# rpm -qa | grep -Ei 'nova|urllib3|request|six'
requests-2.6.0-1.noarch
python-novaclient-2.23.0.post13-1.noarch 
nova-2015.1.0rc1-1.noarch
six-1.9.0-1.noarch
nova-docker-0.0.0.post183-1.noarch
urllib3-1.10.1-1.noarch

Keystone、Glance和Neutron按预期工作，加上nova获取方法，如nova服务列表。已验证所有密码和配置文件。当发出nova boot cmd时，我得到了下面详述的htp500错误
