Python 使用oslo.vmware管理ESXI虚拟机

oslo.vmware是OpenStack通用框架中的一部分，主要用于实现对虚拟机的管理任务，借助oslo.vmware模块我们可以管理Vmware ESXI集群环境。

读取所有节点主机

from oslo_vmware import api
from oslo_vmware import vim_util
import urllib3

urllib3.disable_warnings()

session = api.VMwareAPISession(
            '127.0.0.1',
            'admin@vsphere.com',
            '123456',
             1,0.1)


#result1 = session.invoke_api(vim_util,'get_objects',session.vim, 'HostSystem', 100)

#print(result1.objects[0])
# rep2 = session.invoke_api(vim_util,'get_object_properties_dict',session.vim, result1.objects[0].obj,'vm')

res = session.invoke_api(vim_util,"get_objects",session.vim,"ResourcePool",100)

print(res)

获取所有区域：

from oslo_vmware import api
from oslo_vmware import vim_util
import urllib3

urllib3.disable_warnings()

session = api.VMwareAPISession(
            '127.0.0.1',
            'admin@vsphere.com',
            '123456',
             1,0.1)


res = session.invoke_api(vim_util,"get_objects",session.vim,"ComputeResource",100)

addr = []
for i in res.objects:
    addr.append(i.propSet[0][1])

print(addr)

获取所有主机列表:

from oslo_vmware import api
from oslo_vmware import vim_util
import urllib3

urllib3.disable_warnings()

session = api.VMwareAPISession(
            '127.0.0.1',
            'admin@vsphere.com',
            '123456',
             1,0.1)

res = session.invoke_api(vim_util,"get_objects",session.vim,"HostSystem",1000)

addr = []
for i in res.objects:
    addr.append(i.propSet[0][1])

print(addr)

获取 HostSystem MO

from oslo_vmware import api
from oslo_vmware import vim_util
import urllib3

urllib3.disable_warnings()

session = api.VMwareAPISession(
            '127.0.0.1',
            'admin@vsphere.com',
            '123456',
             1,0.1)


res = session.invoke_api(vim_util,"get_objects",session.vim,"HostSystem",1000)

# 我们随意选取一个 ESXi Host, 并且打印其 Object
host_obj = res.objects[0].obj


# 获取 HostNetworkSystem MO, 并打印其 Value
host_network_system_val = session.invoke_api(vim_util,
    'get_object_properties_dict',session.vim,host_obj,'configManager.networkSystem')

print(host_network_system_val)

            'admin@vsphere.com',
            '123456',
             1,0.1)

                            100)


for each in computeResource.objects:
    print("资源清单: {}".format(each[1][0][1]))

res = session.invoke_api(vim_util,"get_objects",session.vim,"HostSystem",100)


tim = 0
for each in res.objects:

    tim = tim +1

    stats = session.invoke_api(vim_util, 'get_object_properties_dict', session.vim,
                                  each.obj,'summary.runtime.powerState')

    addr = session.invoke_api(vim_util, 'get_object_properties_dict', session.vim,
                                  each.obj,'summary.config.name')

    print("主机地址: {} 	 状态: {}".format(addr.get("summary.config.name"),stats.get("summary.runtime.powerState")))

读取虚拟机状态

from oslo_vmware import api
from oslo_vmware import vim_util

print(instance)

stats = session.invoke_api(vim_util, 'get_object_properties_dict', session.vim,
                           instance, 'summary')


print(stats)

使用com.vmware.vcenter_client管理虚拟机。

import requests
import urllib3
from vmware.vapi.vsphere.client import create_vsphere_client

session = requests.session()
session.verify = False
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

vsphere_client = create_vsphere_client(server='127.0.0.1', username='admin@vsphere.com', password='123456', session=session)

# 列出所有虚拟机
ref = vsphere_client.vcenter.VM.list()
print(ref)

# 通过虚拟机的名称来进行过滤
ref = vsphere_client.vcenter.VM.list( vsphere_client.vcenter.VM.FilterSpec(names={'Baidu-NLP01'}) )

# 列出标准网络
filter = vsphere_client.vcenter.Network.list()
print(filter)

'''
它的 type 有三种类型：
DISTRIBUTED_PORTGROUP：vcenter 创建和管理的网络；
OPAQUE_NETWORK：VSphere 之外的设备所创建，但是 vSphere 却可以知道网络的名称和标识符，所以宿主机和虚拟机的网卡才能够连接到；
STANDARD_PORTGROUP：ESX 创建和管理的网络。
'''

filter = Network.FilterSpec(names={'vlan  164'},types={Network.Type.STANDARD_PORTGROUP})
