? 作為一個VMware的員工，一直用命令行操作，終于被迫需要使用pyvmomi了，體驗了一下，文檔很少，摸索起來略有費勁兒 ，趕緊把心得記錄下來。

1. PyVmomi可以在esxi host上面直接用，也可以在任何的linux系統上用，遠程連接到VC或者host上進行操作。

2. 如果要操作vDS Swtich，必須要連接到VC上進行創建，否則在host上直接操作會失敗，并在hostd.log里產生如下的異常：

2018-02-27T06:45:07.442Z verbose hostd[1001392607] [Originator@6876 sub=PropertyProvider opID=9c8882ef user=root] [RecordAndNotifyChangeInt] No listeners on haTask-ha-folder-network-vim.Folder.createDistributedVirtualSwitch-2021163135 - bailing out

2018-02-27T06:45:07.443Z info hostd[1001392607] [Originator@6876 sub=Default opID=9c8882ef user=root] AdapterServer caught exception: N5Vmomi5Fault12NotSupported9ExceptionE(Message is: ,
--> Fault cause: vmodl.fault.NotSupported
--> Fault Messages are:
--> (null)
--> )

3. 通過linux VM 連接到VC，創建vDS Switch的代碼:

兩個常用到的函數寫在最前面

?

def wait_for_task(task, actionName='job', hideResult=False):
? ?"""
? ?Waits and provides updates on a vSphere task
? ?"""
? ?while task.info.state == vim.TaskInfo.State.running:
? ?time.sleep(2)
? ?if task.info.state == vim.TaskInfo.State.success:
? ? ? if task.info.result is not None and not hideResult:
? ? ? ? ?out = '%s completed successfully, result: %s' % (actionName, task.info.result)
? ? ? ? ?print (out)
? ? ? else:
? ? ? ? ?out = '%s completed successfully.' % actionName
? ? ? ? ?print (out)
? ?else:
? ? ? out = '%s did not complete successfully: %s' % (actionName, task.info.error)
? ? ? raise task.info.error
? ? ? print (out)
? ?return task.info.result

def get_obj(content, vimtype, name):
? ?"""
? ?Get the vsphere object associated with a given text name
? ?"""?
? ?obj = None
? ?container = content.viewManager.CreateContainerView(content.rootFolder, vimtype, True)
? ?for c in container.view:
? ? ? if c.name == name:
? ? ? ? ?obj = c
? ? ? break
? ?return obj

正文開始

至此已經成功的創建了vds switch到esxi host上了。

在host上用命令行查看??esxcfg-vswitch -l:

DVS Name Num Ports Used Ports Configured Ports MTU Uplinks
vds111 3236 3 512 1500 vmnic4

DVPort ID In Use Client
0 1 vmnic4

但可以發現，DVPort ID 并不是我給出的uplink0, 而且并沒有vm的portid創建出來。待續。
