>>> '.'.join('suo.piao.xxx'.split('.')[:-1])
>>> 'suo.piao'

先按“点”分隔开，得到list，舍去最后一个，再用join将这个list连接起来，用到类中，就是这样的：

>>> '.'.join(self.__module__.split('.')[:-1])

通过availability_zone参数可以将虚拟机强制调度到指定的计算节点，但是默认的该参数只能由admin使用，若要普通用户使用，在nova的policy.json中，将"compute:create:forced_host": "is_admin:True"，这条规则改为"compute:create:forced_host": ""


命令行：

nova boot --image c796de54-25f8-405e-afdd-e03003a9e62a --nic net-id=ba05e057-1eb8-4cb2-af58-9b99a72df5ed --flavor 2 --availability_zone nova:server-76 vm
