在測試SCVMM SP1的過程中，添加虛擬主機過程存在報錯，但虛擬主機可以添加成功， 模板創建虛擬機的過程中報錯，無法創建虛擬機。報錯信息如下：
Error (2912)
An internal error has occurred trying to contact the xxx.com server: NO_PARAM: NO_PARAM.
WinRM: URL: [http://xxx:5985], Verb: [INVOKE], Method: [GetError], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/microsoft/bits/BitsClientJob?JobId={F99F233C-4795-4805-B968-764A852EF945}]
Unknown error (0x80072f0d)
Recommended Action
Check that WS-Management service is installed and running on server xxx.com. For more information use the command "winrm helpmsg hresult". If xxx.com is a host/library/update server or a PXE server role then ensure that VMM agent is installed and running.
解決辦法：
百度查找未果，Google無法打開頁面，通過SOHU的搜索查看國外的博客解決。原因在SCVMM服務器上同時安裝了App Controller角色，卸載掉App Controller 後，添加虛擬主機成功，應用模板創建虛擬機成功，故障解決。
