Question

我是python和openstack的新手，所以请不要失去你的冷静：）

这里我试图实例化BareMetalNodeManager类对象（来自np_orchestration.py）。

np_orchestration.py

from baremetal import BareMetalNodeManager
from novaclient import base

class np_orchestration:
    def provisionNodes(self):
        obj = BareMetalNodeManager(base.ManagerWithFind);
        var =        obj.create(self,"192.168.XXX.XXX",1,514,1,"00:0C:29:XX:XX:XX","192.168.XXX.XXX","XXXX","XXXX")
        print var

obj = np_orchestration()
obj.provisionNodes()

这个类（位于baremetal.py中）需要base.ManagerWithFind作为参数（这是一个抽象类）

baremetal.py

class BareMetalNodeManager(base.ManagerWithFind):
"""
Manage :class:`BareMetalNode` resources.
"""
resource_class = BareMetalNode

def create(self,
           service_host,
           cpus,
           memory_mb,
           local_gb,
           prov_mac_address,
           pm_address=None,
           pm_user=None,
           pm_password=None,
           terminal_port=None):
    """
    Create a baremetal node.

    :param service_host: Name of controlling compute host
    :param cpus: Number of CPUs in the node
    :param memory_mb: Megabytes of RAM in the node
    :param local_gb: Gigabytes of local storage in the node
    :param pm_address: Power management IP for the node
    :param pm_user: Username for the node's power management
    :param pm_password: Password for the node's power management
    :param prov_mac_address: MAC address to provision the node
    :param terminal_port: ShellInABox port
    :rtype: :class:`BareMetalNode`
    """
    body = {'node': {'service_host': service_host,
                    'cpus': cpus,
                    'memory_mb': memory_mb,
                    'local_gb': local_gb,
                    'pm_address': pm_address,
                    'pm_user': pm_user,
                    'pm_password': pm_password,
                    'prov_mac_address': prov_mac_address,
                    'terminal_port': terminal_port}}

    return self._create('/os-baremetal-nodes', body, 'node')

我尝试这样做时出现以下错误：

Traceback (most recent call last):
