通过Wmi实现Hyper-V远程管理(一)

最近公司需要做Hyper-V的远程管理，在现有产品基础上扩展对Hyper V的管理，实现远程开关机、远程开启虚拟机会话，其他内容可查看MSDN中有对Hyper-V的描述和相关实例代码、 Wmi操作hyper的工具类、hyper-V

ok，废话不说，正文开始...

1.安装hyper-v虚拟机，这里安装的是2012版，安装好之后创建两个虚拟机

2.查阅了好多资料，通用的方式是用Wmi来与hyper进行数据交互，通过工具扫描一下hyper的wmi节点

发现一共有22个直属类

每个类都逐个查看一下，发现能够交互的只有3个大类

逐个调用一下：

1 [dynamic: ToInstance, provider("VmmsWmiInstanceAndMethodProvider"), Locale(1033)]
2 class Msvm_ComputerSystem : CIM_ComputerSystem
3 {
4     [read, ArrayType("Indexed")] uint16 AssignedNumaNodeList[];
5     [read, Units("MilliSeconds")] uint64 OnTimeInMilliseconds;
6     [read] uint32 ProcessID;
7     [read] datetime TimeOfLastConfigurationChange;
8     [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);
9 };

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"

这些数字分别代表虚拟机实例的各个状态，如：运行，关机，正在关机，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

保存虚拟机数据的类为 Msvm_ComputerSystem,通过调用Msvm_ComputerSystem可以获取远程hyper下各虚拟机信息，该类包含宿主机的描述：

instance of Msvm_ComputerSystem
{
    AssignedNumaNodeList = NULL;
    Caption = "宿主计算机系统";
    CreationClassName = "Msvm_ComputerSystem";
    Dedicated = NULL;
    Description = "Microsoft 宿主计算机系统";
    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 = {"确定"};
    TimeOfLastConfigurationChange = NULL;
    TimeOfLastStateChange = NULL;
};
