Python 使用oslo.vmware管理ESXI虛擬機

oslo.vmware是OpenStack通用框架中的一部分，主要用於實現對虛擬機的管理任務，借助oslo.vmware模塊我們可以管理Vmware ESXI集群環境。

讀取所有節點主機

from oslo_vmware import api
from oslo_vmware import vim_util
import urllib3

urllib3.disable_warnings()

session = api.VMwareAPISession(
            '127.0.0.1',
            '[e-mail]',
            '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)

獲取所有區域：

from oslo_vmware import api
from oslo_vmware import vim_util
import urllib3

urllib3.disable_warnings()

session = api.VMwareAPISession(
            '127.0.0.1',
            '[e-mail]',
            '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)

獲取所有主機列表:

from oslo_vmware import api
from oslo_vmware import vim_util
import urllib3

urllib3.disable_warnings()

session = api.VMwareAPISession(
            '127.0.0.1',
            '[e-mail]',
            '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)

獲取 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',
            '[e-mail]',
            '123456',
             1,0.1)


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

# 我們隨意選取一個 ESXi Host, 並且打印其 Object
host_obj = res.objects[0].obj


# 獲取 HostNetworkSystem MO, 並打印其 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)

使用com.vmware.vcenter_client管理虛擬機。

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='[e-mail]', password='123456', session=session)

# 列出所有虛擬機
ref = vsphere_client.vcenter.VM.list()
print(ref)

它的 type 有三種類型：
DISTRIBUTED_PORTGROUP：vcenter 創建和管理的網絡；
OPAQUE_NETWORK：VSphere 之外的設備所創建，但是 vSphere 卻可以知道網絡的名稱和標識符，所以宿主機和虛擬機的網卡才能夠連接到；
STANDARD_PORTGROUP：ESX 創建和管理的網絡。
