4. 获得虚拟机快照列表
1 param 2 ( 3 [string]$hostServer = $(throw "param -host server is required."), 4 [string]$vmName = $(throw "param -virtual machine name is required.") 5 ) 6 7 $virtualMachines = Get-WmiObject -Class "MSVM_ComputerSystem" -Namespace "root\virtualization" -ComputerName $hostServer; 8 foreach ($virtualMachine in $virtualMachines) 9 { 10 if($virtualMachine.ElementName -eq $vmName) 11 { 12 # get snapshots of the virtual machine 13 $queryStr = "SELECT * FROM Msvm_VirtualSystemSettingData WHERE SystemName='" + $virtualMachine.Name + "' and SettingType=5"; 14 $snapShots = Get-WmiObject -Query $queryStr -Namespace "root\virtualization" -ComputerName $hostServer; 15 16 foreach ($aSnapShot in $snapShots) 17 { 18 $aSnapShot.ElementName 19 [System.DateTime]::ParseExact($aSnapShot.CreationTime.Substring(0,14), "yyyyMMddHHmmss", $null).ToLocalTime().ToString() 20 $aSnapShot.Notes 21 } 22 } 23 }
5. 根据快照回滚虚拟机
