获取hyper-v和vmware虚机状态

在vmware的PowerCLI和微软的scvmm的PowerShell中可以通过Get-VM命令来获取虚拟机的信息。下面我们用代码的方式去实现，代码相关类方法就是对命令的封装。

vmware api的调用方式：

#region  vm status
public VirtualMachineOperationEnum GetVMStatus(string vmName)
{
    ManagedObjectReference vmMor = util.getServiceUtil().getEntityByName("VirtualMachine", vmName);
    VirtualMachineRuntimeInfo info = (VirtualMachineRuntimeInfo)util.getServiceUtil().GetDynamicProperty(vmMor, "runtime");
    switch (info.powerState)
    {
        case VirtualMachinePowerState.poweredOn:
            return VirtualMachineOperationEnum.On;
        case VirtualMachinePowerState.poweredOff:
            return VirtualMachineOperationEnum.Off;
        case VirtualMachinePowerState.suspended:
            return VirtualMachineOperationEnum.Suspend;
        default:
            return VirtualMachineOperationEnum.Fault;
    }
}

微软api的调用方式：

 #region  vm status
 public VirtualMachineOperationEnum GetVMStatus(string vmName)
 {
     try
     {
         switch (client.GetVirtualMachineByName(vmName).Status)
         {
             case DataContracts.VMComputerSystemStateInfo.Running:
                 return VirtualMachineOperationEnum.On;
             case DataContracts.VMComputerSystemStateInfo.Paused:
                 return VirtualMachineOperationEnum.Paused;
             case DataContracts.VMComputerSystemStateInfo.PowerOff:
                 return VirtualMachineOperationEnum.Off;
             default:
                 return VirtualMachineOperationEnum.Fault;
         }
     }
     catch { return VirtualMachineOperationEnum.Fault; }
 }
