Bulk Virtual Machines Deployment and Zero Clicks Part 1

A recent project revisited deploying virtual machines via PowerCli. Its fair to say this isn’t a new tool but sometimes over looked.

Part 1 /  Part 2

My requirements were to deploy :

  • 100+ virtual machines (within a few hours)
  • domain join all machines
  • license the OS
  • various virtual machine specifications
  • various Windows OS versions.
  • to two different data centers within a linked vCenter setup
  • to resource pools
  • to different data stores
  • to different networks

 

The constraints:

  • vSphere 6.0 update 2
  • no budget for third party automation tools
  • small window of opportunity to deploy the VMs

 

On the plus side there was:

o    Loads of available CPU and RAM
o    Large datastores presented
o    Subnets prepared
o    Stretched VLANs across Data Centers

 

The tools I used to the task

  • Excel (CSV)
  • Notepad++
  • PowerCLi

 

The CSV file example

# Example Bulk_VMs_Deploy.csv

Template Datastore VMhost Custspec VMname IPaddress Subnet Gateway
2012_Template Storage1 ESXi.domain 2012_Spec test2003VL1 192.168.0.191 255.255.255.0 192.168.0.1
PDNS SDNS ResourcePool RAM CPU VLAN Size Format
192.168.0.10 127.0.0.1 resource1 2 2 VM Network 10 thin

 

The Script

# Automate the deployment of customised virtual machines deployed in vSphere 6.0. Tested against u2
#
# Prereq’s
# 1) Populate the a CSV file called Bulk_VMs_Deploy.csv
# 2) Create a Windows Server template
# 3) Create a customization spec within vSphere for Windows
# 4) Run Bulk_VMs_Deploy.ps1 script via PowerCli as administrator (CSV file must be stored in the same location where the script is run from)

  • Bulk guest shutdown
  • Bulk power on virtual machines
  • Bulk power off virtual machines
  • Bulk Delete Virtual Machines from disk
  • Bulk change Computer Object OU

Check if an AD user has a roaming profile configured (PowerShell) – OneScript Team

Check if an AD user has a roaming profile configured (PowerShell)

This script can query specified active directory users whether or not a roaming profile was configured.

Scenarios

IT admins may care about which users has a roaming profile was configured. This script can help IT admins check whether or not a roaming profile was configured.

Script

Step 1: Run the script in the Windows PowerShell Console, type the command: Import-Module <Script Path> at the prompt.  For example, type Import-Module C:\Script\CheckIfProfileExists.psm1

This is shown in the following figure.

Step 2: Type the command Get-Help Get-OSCADUserRoamingProfile -Full to display the entire help file for this function, such as the syntax, parameters, or examples.
