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.


## Create 8 Gen2 Virtual Machines
## 4 vCPU per VM
## 1 GB per VM
## C: drive 50 GB Dynamic
## D: drive 50 GB Dynamic
## NIC renamed to MGMT
$vSwitchName01 = "NIC - PRI"
$InstallRoot = "E:\DEMO"
$VMName = "HV-0"

## How much VM's 1..8 = 8 VM's
1..4 | % {
New-VHD -Path ($InstallRoot + "\$VMName" + "$_\" + "\$VMName" + "$_" + "_C.vhdx") -SizeBytes 50GB -Dynamic
New-VHD -Path ($InstallRoot + "\$VMName" + "$_\" + "\$VMName" + "$_" + "_D.vhdx") -SizeBytes 50GB -Dynamic
New-VM -VHDPath ($InstallRoot + "\$VMName" + "$_\" + "\$VMName" + "$_" + "_C.vhdx") -Generation 2 -MemoryStartupBytes 1GB -Name ("$VMName" + "$_") -Path $InstallRoot -SwitchName $vSwitchName01

Set-VMProcessor -VMName ("$VMName" + "$_") -Count 4
Set-VM -VMName ("$VMName" + "$_") -AutomaticStopAction ShutDown -AutomaticStartAction StartIfRunning
Enable-VMIntegrationService ("$VMName" + "$_") -Name "Guest Service Interface"

Rename-VMNetworkAdapter -VMName ("$VMName" + "$_") -NewName "MGMT"
Set-VMNetworkAdapter -VMName ("$VMName" + "$_") -Name "MGMT" -DeviceNaming On

Add-VMScsiController -VMName ("$VMName" + "$_")
Add-VMHardDiskDrive -VMName ("$VMName" + "$_") -ControllerType SCSI -ControllerNumber 1 -ControllerLocation 0 -Path ($InstallRoot + "\$VMName" + "$_\" + "\$VMName" + "$_" + "_D.vhdx")

Start-VM -Name ("$VMName" + "$_") | Out-Null
}

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