问题解决：
修改文件"/usr/lib/python2.7/site-packages/novadocker/virt/docker/driver.py"： spawn函数中增加try、catch： try: image = self.docker.inspect_image(self._encode_utf8(image_name)) except errors.APIError: image = None

问题解决：
创建 /usr/share/nova/rootwrap/docker.filters 文件内容：

# nova-rootwrap command filters for setting up network in the docker driver
# This file should be owned by (and only-writeable by) the root user

[Filters]
# nova/virt/docker/driver.py: 'ln', '-sf', '/var/run/netns/.*'
ln: CommandFilter, /bin/ln, root

问题7：

novadocker 创建的容器与在同一网络中的虚拟机不能互相ping通。
原因分析：目前nova-docker不支持安全组。因此未配置安全组规则。

解决办法：
安全组中增加规则。
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
