How to: Create multiple VM’s in Hyper-V within a few seconds

Automation is one of my favorite things. Some actions are just time consuming, so let’s automate these things!! For example, create a demo environment within Hyper-V. This environment needs 8 VM’s. With a few lines of code, this is realy easy to automate, off course with PowerShell.

Within a few seconds, I’ve 8 VM’s up and running.

How to: Create a VM within a few second in Hyper-V 2012 R2

In some cases I’ve to create multiple VM’s within my Hyper-V environment. You can choose to create and configure each VM manually, but you can also use PowerShell. Now you can see how powerfull PowerShell really is! I’ve created multiple VM’s within a few seconds and ready to rock! I’ve created the following script. The only thing you’ve to do, is changing some variables :)

In this example the script will create a new VM named RES-MGN01. The VM will be configured with 2 GB, using Dynamic Memory. The VM is using a differencing disk (VHDK) with a Windows Server 2012 R2 sysprepped parent VHDX, placed on an SSD disk (P: drive) in my server. The virtual switch the VM is connected to, is named NIC – WAN.

$VMName = “RES-MGN01″
$VMMemMaxBytes = 2048MB
$VHDXName = “OS.vhdx”
$VMMemStartup = 512MB
$VMMemMinBytes = 512MB
$VMPath = “E:\”
$VHDParent = “P:\Hyper-V Parents\TMPL-W2012R2DC\Virtual Hard Disks\TMPL-W2012R2DC.vhdx”
$VMSwitchName = “NIC – WAN”

New-VM -Name $VMName -Path $VMpath$VMName -Generation 2 -SwitchName $VMSwitchName

Set-VM -Name $VMName -DynamicMemory -MemoryStartupBytes 512MB -MemoryMinimumBytes $VMMemMinBytes -MemoryMaximumBytes $VMMemMaxBytes

New-VHD -ParentPath $VHDParent -Path $VMPath\$VMName\$VMName\$VHDXName -Differencing

Add-VMHardDiskDrive -VMName $VMName -Path $VMPath\$VMName\$VMName\$VHDXName

Add-VMDvdDrive -VMName $VMName

Start-VM -Name $VMName
