Exercise 4: Export / Import Lab Virtual Machines

Our Windows Server 2012 cloud-based lab is now functional, but if you’re like me, you may not be using this lab VM 24x7 around-the-clock.  As long as a virtual machine is provisioned, it will continue to accumulate compute hours against your Free 90-Day Windows Azure Trial account regardless of virtual machine state – even in a shutdown state!

To save our compute hours for productive study time, we can leverage the Windows Azure PowerShell module to automate export and import tasks to de-provision our virtual machines when not in use and re-provision our virtual machines when needed again.

In this exercise, we’ll step through using Windows PowerShell to automate:

• De-provisioning lab virtual machines when not in use
• Re-provisioning lab virtual machines when needed again.

Once you’ve configured the PowerShell snippets below, you’ll be able to spin up your cloud-based lab environment when needed in just a few minutes!

Note: Prior to beginning this exercise, please ensure that you’ve downloaded, installed and configured the Windows Azure PowerShell module as outlined in the Getting Started article listed in the Prerequisite section of this step-by-step guide.  For a step-by-step walkthrough of configuring PowerShell support for Azure, see Setting Up Management by Brian Lewis, one of my peer IT Pro Technical Evangelists.

1. De-provision the lab. Use the Stop-AzureVM and Export-AzureVM cmdlets in the PowerShell snippet below to shutdown and export lab VMs when they are not being used.   
    
   NOTE: Prior to running this snippet, be sure to edit the first line to reflect the names of each of your VMs and confirm that the $ExportPath folder location exists.
   
   $myVMs = @("XXXlabad02","XXXlabad01")
    
   $myCloudSvc = "XXXlabad01"
    
   Foreach ( $myVM in $myVMs ) {
    
       Stop-AzureVM -ServiceName $myCloudSvc -Name $myVM
    
       $ExportPath = "C:\ExportVMs\ExportAzureVM-$myVM.xml"
    
       Export-AzureVM -ServiceName $myCloudSvc -name $myVM -Path $ExportPath 
    
   }
    
   After you've verified that all Export files were created in the folder location specified by $ExportPath, you can then de-provision your VMs with the following PowerShell snippet:
    
   $myVMs = @("XXXlabad02","XXXlabad01")
    
   $myCloudSvc = "XXXlabad01"
    
   Foreach ( $myVM in $myVMs ) { 
    
       Remove-AzureVM -ServiceName $myCloudSvc -name $myVM
    
   }
    
2. Re-provision the lab. Use the Import-AzureVM and Start-AzureVM cmdlets in the PowerShell snippet below to import and start lab VMs when needed again.     
    
   $myVNet = "XXXlabnet01"
    
   $myVM1 = "XXXlabad01"
    
   $myVM2 = "XXXlabad02"
     
   $myCloudSvc = "XXXlabad01"
    
   $myStorageAccount = "XXXlabstor01"
    
   Get-AzureSubscription | Set-AzureSubscription -CurrentStorageAccount $myStorageAccount
     
   # Import $myVM1
     
       $ExportPath = "C:\ExportVMs\ExportAzureVM-$myVM1.xml"  
      
       Import-AzureVM -Path $ExportPath | New-AzureVM -ServiceName $myCloudSvc -VNetName $myVNet
    
       Start-AzureVM -ServiceName $myCloudSvc -name $myVM1
    
   # Import $myVM2
    
       $ExportPath = "C:\ExportVMs\ExportAzureVM-$myVM2.xml"  
      
       Import-AzureVM -Path $ExportPath | New-AzureVM -ServiceName $myCloudSvc 
     
       Start-AzureVM -ServiceName $myCloudSvc -name $myVM2
