通過Wmi實現Hyper-V遠程管理(一)

最近公司需要做Hyper-V的遠程管理，在現有產品基礎上擴展對Hyper V的管理，實現遠程開關機、遠程開啟虛擬機會話，其他內容可查看MSDN中有對Hyper-V的描述和相關實例代碼、 Wmi操作hyper的工具類 、hyper-V

ok，廢話不說，正文開始...

 

1.安裝hyper-v虛擬機，這里安裝的是2012版，安裝好之后創建兩個虛擬機

 

 

2.查閱了好多資料，通用的方式是用Wmi來與hyper進行數據交互，通過工具掃描一下hyper的wmi節點

發現一共有22個直屬類

每個類都逐個查看一下，發現能夠交互的只有3個大類

逐個調用一下：

[dynamic: ToInstance, provider("VmmsWmiInstanceAndMethodProvider"), Locale(1033)]
class Msvm_ComputerSystem : CIM_ComputerSystem
{
    [read, ArrayType("Indexed")] uint16 AssignedNumaNodeList[];
    [read, Units("MilliSeconds")] uint64 OnTimeInMilliseconds;
    [read] uint32 ProcessID;
    [read] datetime TimeOfLastConfigurationChange;
    [Implemented, ValueMap{"0", "4096", "32768", "32769", "32770", "32771", "32772", "32773", "32774", "32775", "32776", "32777", "32778"}, Bypass_GetObject, ModelCorrespondence{"CIM_EnabledLogicalElement.RequestedState"}] uint32 RequestStateChange([IN, ValueMap{"2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "..", "32768..65535"}, ModelCorrespondence{"CIM_EnabledLogicalElement.RequestedState"}] uint16 RequestedState, [OUT] CIM_ConcreteJob ref Job, [IN, SubType("Interval"): ToInstance ToSubClass] datetime TimeoutPeriod);
};

其中：

"0", "4096", "32768", "32769", "32770", "32771", "32772", "32773", "32774", "32775", "32776", "32777", "32778"

"2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "..", "32768..65535"

這些數字分別代表虛擬機實例的各個狀態，如：運行，關機，正在關機，等等。如：

    0             Unknown 
    2            Running
    3            Off
    32768    Paused        
    32769    Suspended     
    32770    Starting       
    32771    Snapshotting  
    32772    Migrating
    32773    Saving         
    32774    Stopping  
    32775    Deleted
    32776    Pausing        
    32777    Resuming  

 

 

保存虛擬機數據的類為 Msvm_ComputerSystem,通過調用Msvm_ComputerSystem可以獲取遠程hyper下各虛擬機信息，該類包含宿主機的描述：

instance of Msvm_ComputerSystem
{
    AssignedNumaNodeList = NULL;
    Caption = "宿主計算機系統";
    CreationClassName = "Msvm_ComputerSystem";
    Dedicated = NULL;
    Description = "Microsoft 宿主計算機系統";
    ElementName = "HYPER-V";
    EnabledDefault = 2;
    EnabledState = 2;
    HealthState = 5;
    IdentifyingDescriptions = NULL;
    InstallDate = NULL;
    Name = "HYPER-V";
    NameFormat = NULL;
    OnTimeInMilliseconds = NULL;
    OperationalStatus = {2};
    OtherDedicatedDescriptions = NULL;
    OtherEnabledState = NULL;
    OtherIdentifyingInfo = NULL;
    PowerManagementCapabilities = NULL;
    PrimaryOwnerContact = NULL;
    PrimaryOwnerName = NULL;
    ProcessID = NULL;
    RequestedState = 12;
    ResetCapability = 1;
    Roles = NULL;
    Status = "OK";
    StatusDescriptions = {"確定"};
    TimeOfLastConfigurationChange = NULL;
    TimeOfLastStateChange = NULL;
};
