hyper-V 虚拟机的创建和内存管理

butter7372

在Hyper-V的管理界面中可以根据向导轻易的创建出一台虚拟机,不过Hyper-V作为企业级的应用,还提供了WMI接口供外部操作. 以C#为例来通过程序创建VM. 需要通过Msvm_VirtualSystemManagementService.DefineVirtualSystem方法来创建一个虚拟机 // Get Msvm_VirtualSystemManagementService Object ManagementClassmc = new ManagementClass(scope, new ManagementPath("Msvm_VirtualSystemManagementService"), null); ManagementObject objVSMS = null foreach (ManagementObject obj in mc.GetInstances()) { objVSMS = obj; } inParams = objVSMS.GetMethodParameters("DefineVirtualSystem"); // Create Msvm_VirtualSystemGlobalsettingData Object ManagementPathwmiPath = new ManagementPath("Msvm_VirtualSystemGlobalsettingData"); ManagementClass serviceClass = new ManagementClass(scope, wmiPath, null); ManagementObject data= serviceClass.CreateInstance(); data["ElementName"] = "vmName"; data["ExternalDataRoot"] = "c:\vms\vmName"; // VM Path, if don't specify, it will use default data["SnapshotDataRoot"] = "c:\snapshots\vmName"; // snapshot path, if don't specify, it will be same with ExternalDataRoot inParams["ResourcesettingData"] = null; inParams["Sourcesetting"] = null; inParams["SystemsettingData"] = data.GetText(TextFormat.CimDtd20); outParams = objVSMS.InvokeMethod("DefineVirtualSystem", inParams, null); 　　Remark:这样创建出来的VM不包含任何资源(内存除外), 如果要想使用,还需要给它创建硬盘,网卡的资源文件. 如何取得已经存在的VM? select * from Msvm_ComputerSystem Where ElementName = 'vmName'" 如何打开关闭VM Msvm_ComputerSystem.RequestStateChange // 2 - turn on VM, 3 - turn off vm 如果装了VM里的OS装了VM guest,还可以通过Msvm_ShutdownComponent.InitiateShutdown 来安全的关闭VM SELECT * FROM Msvm_ShutdownComponent WHERE SystemName='vmName' 可以取得Msvm_ShutdownComponent对象 如何取得内存对象　　SELECT * FROM Msvm_MemorySettingData WHERE InstanceID LIKE "%Microsoft:vmName%" 如何修改内存大小 Msvm_MemorySettingData 对象的VirtualQuantity,Reservation,Limit 定义了内存的大小,用Msvm_VirtualSystemManagementService.ModifyVirtualSystemResources可以改变内存的大小 SO娱乐城：真_人.足球.彩票齐全| 开户送10元.首存送58元.手机可投╡注任何游戏顶级信用╡提现即时到账SO.CC
