使用实例Hyper-V V2

本文关键字：V2 Hyper-V 实例 | 更新日期: 2023-09-27 18:12:02

我正在尝试使用c#和ApplySnapshot方法将快照应用到hyper V虚拟机。

ApplySnapshot方法

但我似乎在挣扎，因为没有该方法的样例类。如果有人能帮助提供一个样本或样本项目，我将不胜感激。

多谢比利

使用实例Hyper-V V2

本例将应用虚拟机最近的快照。这可以很容易地更改为应用选定的快照，通过将'lastSnapshot'替换为代表您想要应用的快照的Msvm_VirtualSystemSettingData实例。

public static class VirtualSystemSnapshot
{
    public static object Revert(VirtualMachine vm)
    {
        ManagementScope scope = new ManagementScope("''''" + ServerName + "''Root''Virtualization''V2", Options);
        using (ManagementObject virtualMachine = WmiUtilities.GetVirtualMachine(vmElementName, scope)) {
            using (ManagementObject virtualSystemSettingData = WmiUtilities.GetVirtualSystemSettingData(scope, virtualMachine)) {
                using (ManagementObject virtualSystemSnapshotService = WmiUtilities.GetVirtualSystemSnapshotService(scope)) {
                    using (ManagementObject lastSnapshot = WmiUtilities.GetFirstObjectFromCollection(virtualSystemSettingData.GetRelated("Msvm_VirtualSystemSettingData", "Msvm_ParentChildSettingData", null, null, null, null, false, null))) {
                        using (ManagementBaseObject inParams = virtualSystemSnapshotService.GetMethodParameters("ApplySnapshot")) {
                            inParams("Snapshot") = lastSnapshot;
                            // In order to apply a snapshot, the virtual machine must first be saved
                            RequestStateChange.Main(vm, RequestStateChange.RequestedState.Save, false);
                            using (ManagementBaseObject outParams = virtualSystemSnapshotService.InvokeMethod("ApplySnapshot", inParams, null)) {
                                WmiUtilities.ValidateOutput(outParams, scope);
                                // Now that the snapshot has been applied, start the VM back up
                                RequestStateChange.Main(vm, RequestStateChange.RequestedState.Start, false);
                            }
                        }
                    }
                }
            }
        }
    }
}
