Next, we will look at some scripts that can be used to automate the virtual machine import, export, and snapshot processes. This section is relatively simple as we will be using a for-each loop to iterate across all virtual machines and perform these activities.
For this particular example, we will be using a single script to illustrate all three processes:
$vminfo = Get-VM
As you can see in the preceding piece of code, we will extract the information about all the virtual machines and store it in a variable, $vminfo
:
Foreach ($vm in $vminfo) {
Next, let's iterate across all the virtual machines stored in the $vminfo
variable and create a snapshot of the virtual machines using the Checkpoint-VM
cmdlet:
Checkpoint-VM -Name $vm.name -SnapshotName BeforeInstallingUpdates }
Next, let's export all the virtual machines to a location using the Export-VM
cmdlet. We can use a similar for-loop technique to export all...
