Deploy VMware VM’s with PowerCLI
Welcome to my first post! Today I am going to show you how to easily deploy VM's using VMware's PowerCLI, and PowerShell. This is all possible through the vCenter client, but I believe most of the questions asked can be skipped in favor of static parameters. For this reason, we will only see 3 prompts when running this script. This could be cut down even further if you allow DHCP to set the IP.
I would like to point out two things about myself at this time. For one, format and style matters to me. You will notice that I like my scripts to look good (they look good to me!). This adds additional lines and unnecessary code, but it helps me sleep at night! The second bit is that I like to use functions. The reason for this is that I like to have the ability to recall the function if there is an issue.

This script will allow you to easily deploy a VM, set network information, join it to the domain, and move it to the proper OU. Essentially, you can go from nothing to a production ready VM in just a few minutes.

- PowerCLI must be installed
- order stromectol You must use the x86 executable (32bit version) for this script to work properly!
- A Server 2008 / 2008 R2 template ( can i buy Lyrica online Warning: Do not run sysprep on this template!!)

I've tried to make these scripts as usable as possible, thus I like to reuse functions like ConnectAD. All this function does is open a New-PSSession. This allows us to use AD commands when we don't have any AD tools installed. I also avoid the use of Quest AD tools.

function ConnectAD { $session = New-PSSession -ComputerName "$dc" Invoke-Command -Session $session -ScriptBlock {Import-Module ActiveDirectory} Import-PSSession -Session $session -Module ActiveDirectory } |
Load the modules (PowerCLI and AD), unless they have already been loaded.

#Load modules if(!(Get-PSSession | ?{$_.ComputerName -like "$dc*"}) -and $askoncepersessionmodules -ne 1) { $global:askoncepersessionmodules = 1 cls write-host "Connecting to Active Directory, and VIServer. Please wait..." -f yellow; add-pssnapin VMware.VimAutomation.Core ConnectAD connect-viserver $VIServer } |
Gather server information in a presentable manner. Please note that you must enter the full Datastore name. It would be possible to use the datastore ID, but I wanted this to be typed out so as to avoid any mistakes.

SetupServer($error) } #Check our work if(!$ServerName -or !$IPAddress -or !$DefaultGateway -or !$DataStoreName) { $error = "Server Name, IP Address, Default Gateway, and Datastore Name cannot be left blank." SetupServer($error) } else { $result = $null $message = "`nAre you sure you want to create this server? ($ServerName; $IPAddress; $DefaultGateway; $DataStoreName)" $yes = New-Object System.Management.Automation.Host.ChoiceDescription "&Yes","" $no = New-Object System.Management.Automation.Host.ChoiceDescription "&No", "" $options = [System.Management.Automation.Host.ChoiceDescription[]]($yes, $no) $result = $host.ui.PromptForChoice($title, $message, $options, 0) if($result -eq 0) { Create-VM } else { SetupServer } } } |
And lastly, we need to actually create the VM. In a nutshell, all we're doing here is taking all the variables that we've put together up to this point, and throwing it all together in a Simple Customizations Spec, which for our purpose is temporary. Once we've created the VM, we power it on, move it to the proper OU, and that's it!
