　　1. 启动

•   }  
  
• }  
  
• $vmName + "startup Finished!"  
  

　　
2.  关闭
　　
viewplain

• $hostServer = "shlihu-2k8r2";  
  
• $vmName="Win7-Pro2";  
  
•   function GetImageState   
  
• {   
  
•       param  
  
•       (

•        $currentState = GetImageState -image:$image -hostserver:$hostServer;  
  
•        if ($currentState -eq $state)  
  
•        {  
  
•         return;  
  
•        }  
  
•          
  
•        if ($timeOut -le 0)  
  
•        {  
  
•         throw "Wait for image [$image] to state [$state] time out.";

•   }  
  
• }  
  
• $vmName + "Shutdown Finished!"  
  

　　
3. 获取虚拟机状态
viewplain

• $hostServer = "shlihu-2k8r2";  
  
• $vmName="Win7-Pro2";  
  
• $status = -1   
  
• $virtualMachines = Get-WmiObject -Class "MSVM_ComputerSystem" -Namespace "root\virtualization" -ComputerName $hostServer   
  
• foreach ($virtualMachine in $virtualMachines)  
  
• {  
  
•      if ($vmName -ieq $virtualMachine.ElementName)  
  
•      {  
  
•          $status = $virtualMachine.EnabledState  
  
•          break  
  
•      }  
  
• }  
  
•    
  
• switch($status)  
  
• {  
  
•      -1    {throw "Cannot get the state of vmName [$vmName] on host server [$hostServer]"}  
  
•      2     {"Running."}  
  
•      3     {"Closed."}   
  
•      32768 {"Paused."}   
  
•      32769 {"Saved."}   
  
•      32770 {"Starting."}   
  
•      32773 {"Saving."}   
  
•      32774 {"Stopping."}   
  
•      32776 {"Pausing."}  
  
•      32777 {"Restoring."}   
  
•      default {"Unknow Status."}  
  
• }  
  

　　
4. 获取snapshot列表
viewplain

• $hostServer = "shlihu-2k8r2";  
  
• $vmName="Win7-Pro2";  
  
•   
  
• $virtualMachines = Get-WmiObject -Class "MSVM_ComputerSystem" -Namespace "root\virtualization" -ComputerName $hostServer;   
  
• foreach ($virtualMachine in $virtualMachines)   
  
• {     
  
•      if($virtualMachine.ElementName -eq $vmName)  
  
•      {  
  
•          # get snapshots of the virtual machine  
  
•          $queryStr = "SELECT * FROM Msvm_VirtualSystemSettingData WHERE SystemName='" + $virtualMachine.Name + "' and SettingType=5";  
  
•          $snapShots = Get-WmiObject -Query $queryStr -Namespace "root\virtualization" -ComputerName $hostServer;  
  
•    
  
•          foreach ($aSnapShot in $snapShots)  
  
•          {  
  
•             $aSnapShot.ElementName  
  
•             [System.DateTime]::ParseExact($aSnapShot.CreationTime.Substring(0,14), "yyyyMMddHHmmss", $null).ToLocalTime().ToString()  
  
•             $aSnapShot.Notes  
  
•          }  
  
•      }  
  
• }  
  

　　
5. 恢复snapshot
viewplain

• $hostServer = "shlihu-2k8r2";  
  
• $vmName="Win7-Pro2";  
  
• $snapshotName ="Win7-Pro2 -VS2010-Silk2010r2-Completed-Install"

•   )  
  
•   $virtualMachines = Get-WmiObject -Class "MSVM_ComputerSystem" -Namespace "root\virtualization" -ComputerName $hostServer;  
  
•   foreach ($virtualMachine in $virtualMachines)  
  
•   {  
  
•    if ($image -ieq $virtualMachine.ElementName)  
  
•    {  
  
•     return $virtualMachine.EnabledState;  
  
•    }  
  
•   }  
  
•   throw "Cannot get the state of image [$image] on host server [$hostServer]";  
  
• }  
  
•    
  
• function WaitImageToState  
  
• {  
  
•   param  
  
•   (  
  
•    [string]$image = $(throw "param -image is required."),  
  
•    [string]$hostServer = $(throw "param -hostserver is required."),  
  
•    [int]$state = $(throw "param -$state is required."),  
  
•    [int]$timeOut = $(throw "param -$timeOut is required.")  
  
•   )   
  
•   do  
  
•   {   
  
•    $timeOut = $timeOut - 5;  
  
•    sleep (5);  
  
•    $currentState = GetImageState -image:$image -hostserver:$hostServer;  
  
•    if ($currentState -eq $state)  
  
•    {  
  
•     return;  
  
•    }  
  
•      
  
•    if ($timeOut -le 0)  
  
•    {  
  
•     throw "Wait for image [$image] to state [$state] time out.";  
  
•    }   
  
•   }while($true);  
  
• }  
  
•    
  
• "Rollback the virtual machine..."  
  
• $virtualMachines = Get-WmiObject -Class "MSVM_ComputerSystem" -Namespace "root\virtualization" -ComputerName $hostServer;  
  
• $virtualSystemService = Get-WmiObject -Class "Msvm_VirtualSystemManagementService" -Namespace "root\virtualization" -ComputerName $hostServer;  
  
• foreach ($virtualMachine in $virtualMachines)  
  
• {     
  
•   if($virtualMachine.ElementName -eq $vmName)  
  
•   {  
  
•    # get snapshot of the virtual machine  
  
•    $queryStr = "SELECT * FROM Msvm_VirtualSystemSettingData WHERE SystemName='" + $virtualMachine.Name + "' and SettingType=5";  
  
•    $snapShots = Get-WmiObject -Query $queryStr -Namespace "root\virtualization" -ComputerName $hostServer;  
  
•    foreach ($aSnapShot in $snapShots)  
  
•    {  
  
•     # revert to specified snapshot  
  
•     if ($aSnapShot.ElementName -ieq $snapshotName)  
  
•     {  
  
•      # apply snapshot  
  
•      $result = $virtualSystemService.ApplyVirtualSystemSnapShot($virtualMachine.__PATH, $aSnapShot.__PATH);  
  
•      if ($result.ReturnValue -ne 0)  
  
•      {  
  
•       throw "Failed to apply snapshot ["+$snapshotName+"] to VM ["+$image+"]";  
  
•      }         
  
•      WaitImageToState -image:$virtualMachine.ElementName -hostserver:$hostServer -state:32769 -timeOut:120;  
  
•     }  
  
•    }  
  
•   }  
  
• }  
  
• "Finished rollback!"  
  

　　6. 网络操作
　　使用powershell重启网络（非常有用）
