Proxmox on Technical Notes

ProxmoxVE Helper Scripts

Thu, 14 Aug 2025 00:00:00 +0000

If you have little experience it might be a bit daunting, which is why I recommend this wonderful project: Proxmox VE Helper-Scripts, where you’ll find hundreds of scripts to make your life easier installing CTs or VMs on top of your Proxmox.

Windows 11 on Proxmox

Mon, 04 Aug 2025 00:00:00 +0000

Complete guide with all the detailed steps to install, configure and access a Windows 11 Pro Virtual Machine (VM) running on top of Proxmox VE.

This virtualization platform enables the deployment and management of virtual machines running Windows Server/10/11 using KVM/QEMU. With advanced integration through the QEMU Guest Agent, VirtIO drivers, and even UEFI Secure Boot with TPM emulation for Windows 11.

Proxmox and UPS: Graceful Shutdown

Fri, 25 Jul 2025 00:00:00 +0000

Having a battery backup system (UPS) is essential for home servers hosting multiple services. But it’s not enough for the UPS to supply power for a few minutes: the critical part is that, in case of a prolonged outage, the entire system shuts down in a controlled and orderly manner. In this article I document how I deployed a solution based on NUT on Proxmox to achieve this.

Home mDNS

Sun, 09 Mar 2025 00:00:00 +0000

Multicast DNS (mDNS) is a networking protocol designed to resolve hostnames to IP addresses within small networks, without the need for a local DNS server. It requires no configuration (zero-configuration) and uses the same programming interfaces, packet formats and operational semantics as unicast Domain Name System (DNS).

It was designed to work as either a standalone protocol or alongside standard DNS servers. mDNS can work together with DNS Service Discovery (DNS-SD), a complementary zero-configuration networking technique specified separately in RFC 6763.

Router with PiHole 6

Sat, 08 Mar 2025 00:00:00 +0000

A couple of months ago I moved the DHCP and DNS services to my home Linux router and left the Pi-Hole 5 service on a separate virtual machine. Despite everything working perfectly, I hit a snag: troubleshooting from PiHole is complicated because all DNS queries are resolved by the router and PiHole sees nothing. So I decided to redesign the setup.

In this post I describe how I install Pi-Hole 6 on my Linux router so it provides DNS, DHCP (with dnsmasq) and ad sinkholing. This involves undoing the native dnsmasq installation.

Self-Hosted Bitwarden

Sun, 02 Mar 2025 00:00:00 +0000

In this post I describe the process of installing a “Bitwarden” server. I’ve been using their Cloud service for several years, but I’ve decided to go with an on-premise home installation.

While researching I discover with surprise that I have two options, the first is to use the official Bitwarden self-hosted (which consumes quite a few resources and seems complex) or go with a lightweight Vaultwarden, a clone of the former, which apparently installs quickly and is simple.

DHCP and DNS Server

Thu, 26 Dec 2024 00:00:00 +0000

In this post I describe how I’ve evolved my home DHCP and DNS server. Until now I had a PiHole dedicated on the network to DHCP, DNS and ad sinkhole. I’ve decided to migrate to a different configuration, move both DNS and DHCP services to the home router (Linux).

I realized that when PiHole went down, the rest of the home services would spiral out of control, despite having the router and internet working, so I’m leaving PiHole exclusively as the ad sinkhole.

Home Automation and Networking

Sat, 08 Apr 2023 00:00:00 +0000

I’m sharing my home networking setup with the option to knock on the door for on-demand access from the Internet. Today’s home networks end up supporting multiple services, and with the rise of home automation things get complicated, so I’ve decided to document it to keep track of everything in the future.

The number of devices grows and maintaining the network of a smart and automated home becomes a priority. I dedicate this post to those Geeks or Techies who, like me, have been deep into the complexity of networking in a home automation network for a long time.

Proxmox: VM from Template

Fri, 07 Apr 2023 00:00:00 +0000

Proxmox VE is a powerful and easy-to-use open-source virtualization platform that enables the deployment and management of virtual machines (VMs with KVM/QEMU) and containers (CTs based on LXC). Proxmox offers Templates to minimize the creation time of new instances of these virtual machines or containers.

In this post I focus on how to create my own Virtual Machine Templates along with a cloud-based image and cloud-init.
