Homelab

My HomeLab anno 2024

My home lab is manly used for testing new stuff released by VMware (70%) en Microsoft (20%) other stuff (10%)

For the Base I use my Home PC

Intel i5 12600k
128 GB Memory
2 x 2TB Samsung 980 and 990 Pro SSD.
Windows 11 Pro
VMware Workstation Pro

On my Home PC running
Server 2022 (Eval for DC)
ESXi801 (16 GB) (NSX Demo Cluster)
ESXi802 (16 GB) (NSX Demo Cluster)
ESXi803 (64 GB) (General Cluster) )
ESXi804 (64 GB) (General Cluster)
ESXi805 (24 GB) (Single Node vSAN Cluster)
ESXi806 (16 GB) (4 Node vSAN Cluster)

For a while I used a 2TB Samsung SSD a Storage for ESXi Server through Truenas
But I wanted a larger storage for all my VM’s.

After reading on William Liam blog Synology DS723+ in Homelab and Synology NFS VAAI Plug-in support for vSphere 8.0

So I did a nice upgrade. Afbeelding met tekst, schermopname, software, nummer

I used not the original Synology Parts. Following parts works fine.
Kingston 16 GB DDR4-3200 notebook memory
WD Red SN700, 500 GB SSD
WD Red Pro, 8 TB

* For Read-Write caching you need 2 SSD devices.

For mouting the NFS shared I created a little powercli script.

My Favorites Visual Studio Code Plugins

When i begon with scripting using PowerShell ISE for Coding.

PowerShell ISE and Visual Studio Code are free coding tools from Microsoft.

But when Visual Studio Code was released back in 2015 i was switching to that. Powershell ISE i still use on a daily base for some basic tasks.

But with de Extenions list for Visual Studio Code getting better and better scripting is much faster and without errors and easyer to read.

The list with favo extensions is getting bigger en bigger.
Which makes my live a little easyer and helpfull.

So the list of my Favorites:
Prettier – Code Formatter
TODO Highlight
Code Spell Checker
Dutch – Code Spell Checker
Code Snap
Error Lens
Hashicorp HCL
HashiCorp Terraform

Because AI is hot I ám currently testing the following plugins
ChatGPT
GitHub CoPilot
GitHub CoPilot Chat

Using the ChatGPT/CoPilot plugins makes scripting even faster

Windows Server 2025 “Preview” deployment with Packer

As Windows Server 2025 Preview is officially released, I wanted to test a  automated build of the Windows Server 2025 Preview release. So that I can deploy this in my home lab and going to test the new features if I can find the time….

About Hashicorp Packer

Hashicorp Packer is a self-contained executable producing quick and easy operating system builds across multiple platforms. Using Packer and a couple of HCL2 files, you can quickly create fully automated template(s) with latest Windows Updates en VMware Tools. When you schedule a fresh builds after patch Tuesday  you have always an up-to-date and fully secured template.

When using VMware customization tools. You can spin up vm’s in minutes.

Automated Windows Server 2025 “Preview” Build

Files you need?
The files and versions I am using at the time of this writing are as follows:

Outside of downloading both Packer and Windows Server 2022 Preview build, you will need the following files:

  • windowsserver2025.auto.pkrvars.hcl – houses the variable values you want to define.
  • windows2025.json.pkr.hcl – the Packer build file
  • Answer file – Generated with Windows System Image Manager (SIM) you can download the file below
  • Custom script file(s) – optional

Other considerations and tasks you will need to complete:

  • Copy the Windows Server 2025 ISO file to a vSphere datastore

Windows Server 2025 unattend Answer file for the automated Packer Build

Like other automated approaches to installing Windows Server, the automated Windows Server 2025 Packer build requires an answer file to provide answers to the GUI automatically and other installation prompts that you normally see in a manual installation of Windows Server.

You will find the scripts here: https://github.com/WardVissers/Packer-Win2025

The only problem that I had was: Switching from Nic from Public to Private

# Set network connections profile to Private mode.

Write-Output ‘Setting the network connection profiles to Private…’

do {

    $connectionProfile = Get-NetConnectionProfile

    Start-Sleep -Seconds 10

} while ($connectionProfile.Name -eq ‘Identifying…’)

Set-NetConnectionProfile -Name $connectionProfile.Name -NetworkCategory Private

Windows Server 2025 Preview (Build: Canary 26052)

I had some time to check out the new version of Server 2025.

For the full upcomming features check: https://ignite.microsoft.com/en-US/sessions/f3901190-1154-45e3-9726-d2498c26c2c9?source=sessions

Download Server 2025 Preview: https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewserver

Server 2025 will come with a lot of features (My Top 20+):

Deploy Windows Core Server 2022 with Server Core App Compatibility Feature on Demand with Packer

I while ago I started with parker to create simple templates for use in my homelab.

It take some time to find the rights scripts and learning en understanding the HCL2 coding

But in related to Security reasons I want to use a Windows Core Server the smaller footprint.

What is Server Core App Compatibility Feature on Demand: https://learn.microsoft.com/en-us/windows-server/get-started/server-core-app-compatibility-feature-on-demand

Installing Features on Demand through Powerschell contains a bug. You may see “failure to download files”, “cannot download”, or errors like “0x800F0954” or file not found.

To Solve that I created I powerschell script to run the install twice: featuresondemand.ps1

You can find al the needed files on my Public Github Packer repository: https://github.com/WardVissers/Packer-Public

When running is showing like this:

VCF 5.0 running inside Nested ESXi server with only 64GB Memory

So I interested to trying to deploy latest release of VMware Cloud Foundation (VCF) 5.0 on my Windows 11 Home PC witch have 128GB and 16 core intel cpu.

William Lee wrote a nice artikel about VMware Cloud Foundation 5.0 running on Intel NUC

Disclaimer: This is not officially supported by VMware, please use at your own risk.

Requirements:

  • VMware Cloud Builder 5.0 OVA (Build 21822418)
  • VCF 5.0 Licenses Through VMUG ADVANTAGE
  • Home PC (Not Special Hardware)
    – 128GB Memory
    – Intel 12600 CPU
    – 4TB of NVME Storage
  • Windows 11 with VMware Workstation 17

Setup

Virtual Machines

  • DC02 (Domain Controller, DNS Server) (4GB 2vcpu)
  • VCF-M01-ESX01 (ESXi 8.0 Update 1a) (64GBGB 1x140GB 2x600NVME 2x NIC) (Every Thin Provisiond)
  • VCF-M01-CB01 (4GB and 4CPU) Only needed through First Deploment

Network settings on my PC

  • 1 IP In my home network
  • 172.16.12.1 (To Fool Cloudbuilder)
  • 172.16.13.1 (To Fool Cloudbuilder)

Procedure:

Install en Configure ESXi

Step 1 – Boot up the ESXi installer from de iso mount and then perform a standard ESXi installation.

Step 2 – Once ESXi is up and running, you will need to minimally configure networking along with an FQDN (ensure proper DNS resolution), NTP and specify which SSD should be used for the vSAN capacity drive. You can use the DCUI to setup the initial networking but recommend switching to ESXi Shell afterwards and finish the require preparations steps as demonstrated in the following ESXCLI commands:

esxcli system ntp set -e true -s pool.ntp.org
esxcli system hostname set –fqdn vcf-m01-esx01.wardvissers.nl

Note: Use vdq -q command to query for the available disks for use with vSAN and ensure there are no partitions residing on the 600GB disks.
Don’t change time server pool.ntp.org.

To ensure that the self-signed TLS certificate that ESXi generates matches that of the FQDN that you had configured, we will need to regenerate the certificate and restart hostd for the changes to go into effect by running the following commands within ESXi Shell:

/bin/generate-certificates
/etc/init.d/hostd restart

Cloudbuilder Config

Step 3 – Deploy the VMware Cloud builder in a separate environment and wait for it to be accessible over the browser. Once CB is online, download the setup_vmware_cloud_builder_for_one_node_management_domain.sh setup script and transfer that to the CB system using the admin user account (root is disabled by default).

Step 4 – Switch to the root user and set the script to have the executable permission and run the script as shown below

su –
chmod +x setup_vmware_cloud_builder_for_one_node_management_domain.sh
./setup_vmware_cloud_builder_for_one_node_management_domain.sh

The script will take some time, especially as it converts the NSX OVA->OVF->OVA and if everything was configured successfully, you should see the same output as the screenshot above.

Step 4 – Download the example JSON deployment file vcf50-management-domain-example.json and and adjust the values based on your environment. In addition to changing the hostname/IP Addresses you will also need to replace all the FILL_ME_IN_VCF_*_LICENSE_KEY with valid VCF 5.0 license keys.

Step 5 – The VMnic in the Cloud Builder VM will acked als a 10GB NIC so I started the deployment not through powershell but normal way in Cloud Builder GUI.

Your deployment time will vary based on your physical resources but it should eventually complete with everything show success as shown in the screenshot below. (I have one retry for finish)

Powercli Delete Orphaned Edge Transport Nodes

I made a little mistake on my Lab Environment. There fore it was required to clean up my last unremoveable edge server.

Sow i made a little powercli script

RemoveOrphanedEdge.ps1

# https://kb.vmware.com/s/article/892835
# https://virtuallyjason.blogspot.com/2020/11/using-nsx-t-api.html

$nsxfqdn = Read-Host “Give the IP of the FQDN from your NSX Server”

$creds = Get-Credential -Message "NSX-T Administrative Credentials:"

}
$base64Creds = [Convert]::toBase64String([System.Text.Encoding]::UTF8.GetBytes(“$($creds.username):$($creds.GetNetworkCredential().password)”))
$header = @{Authorization = “Basic $base64Creds”}
$uri = “https://$nsxserver”

Packer – Vmware Tools + Windows Server + VMTools service not installing correctly

I had a frustrating issue with Packer, specifically with VMware Tools installation.

During the Packer install, I load up a script and have VMware Tools 12.1.5 installed. It seems to install successfully, But I noticed that the VMTools service is not running. I have to re-run setup64.exe via the GUI and do a repair, then I see the service exist and runs, and Packer can discover the IP address of the VM to finish it.

The Solution

I used a older autounattend.xml which i never checked the time zone.
Setting the correcting time zone the trick:

<TimeZone>W. Europe Standard Time</TimeZone>

NSX-T 3.1 Home lab – Part 2

With all the Fabric configuration done we can test our setup.

I’m creating two overlay segments in NSX connected to a Tier-1 gateway, and after that we’ll create a Tier-0 gateway and connect the T1 gateway to it to get North/South connectivity to the overlay resources

Two VMs will be deployed, one VM in each of the two overlay segments

Create a Tier-1 Gateway

The Tier-1 Gateway will initially not be connected to a Tier-0 Gateway (I haven’t configured a T0 gw yet) or an Edge Cluster.

Tier-1 Gateway

Tier-1 Gateway

Create Logical segments

We need two logical segments, both using the Overlay Transport Zone. I’m defining different subnets on them, 10.0.1.0/24 and 10.0.2.0/24.

Connectivity test

This shows that the overlay is working, and note again that the Edge VMs are not in use here.

External connectivity

Traffic is flowing between VMs running on Logical segments inside the NSX-T environment, but what if we want to reach something outside, or reach a VM inside a NSX-T overlay?

Then we need to bring a Tier-0 Gateway in to the mix.

The T-0 gateway can be configured with Uplinks that are connected to the physical network. This is done through a segment which can reach the physical network, normally through a VLAN.

To configure the uplink interfaces we need to have Edge VMs so finally we get to bring those into play as well.

Create segment for uplinks

First I’ll create a segment mapped to VLAN 99 in my lab. Note that I select the VLAN transport zone, and I do not connect the segment to a gateway

Create Uplink VLAN segment

Create Uplink VLAN segment

Create Tier-0 gateway

Now we’ll create a Tier-0 gateway, note that I now also select my Edge cluster.

Create T0 gateway

Static route

To be able to forward traffic out of the NSX-T environment the T0 gateway needs to know where to send queries for IPs it doesn’t control. Normally you would want to configure a routing protocol like BGP or OSPF so that the T0 gateway could exchange routes with the physical router(s) in your network.

I’ve not set up BGP or any other routing protocol on my physical router, so I’ve just configured a default static route that forwards to my physical router. The next hop is set to the gateway address for the Uplink VLAN 99, 192.168.99.1

Static route

Static route

Link T1 gateway to T0 gateway

We’ve done a lot of configuring now, but still we’ve not got connectivity in or out for our VMs. The final step is to connect the Tier-1 gateway to the Tier-0 gateway, and we’ll also activate Route Advertisement of Connected Segments and Service Ports

Test Distributed Firewall

Let’s also do a quick test of the Distributed Firewall feature in NSX-T.

First we’ll create a rule blocking ICMP (ping) from any to my test vm and publish the rule

Summary

Hopefully this post can help someone, if not it has at least helped me.

Now we have working environment so we can go testing some things.
Also scripting/automation against a nsx environment I will look in to!
