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. …
In this post I describe the installation process of a Raspberry Pi4B Rev1.5 (also tested with the Pi3B+) with the Raspberry Pi OS (64-bit) operating system (based on Debian). I normally use these Pis as single-purpose mini servers or for testing and lab work. …
Configuration of a NUC with Ubuntu + Open vSwitch + VLANs + KVM + VMs using netplan and Open vSwitch. The networking is based on OVS and Netplan for both the Host and the virtual machines. Last year I documented here how to configure Open vSwitch with KVM. In this post I’ll get straight to the point, showing the desired final state and how to configure it. …
Every now and then I get the urge to practice my rusty Java skills. I’m going to write a small program to monitor devices on my home network using Java and SNMP. I like to keep my development projects on my private git server (based on gitea). In this post I describe the process of creating a git repository, a Java Project with Eclipse, and how to connect them together. If you use GitHub, the process is identical, although the UI options may look slightly different compared to Gitea. …
Installation of Home Assistant OS (HAOS) on an Intel NUC5i5RYK — a very powerful machine for this task, but I had it available and wanted to make use of it. I started by setting it up on a Raspberry Pi4B, moved to a virtual machine (with considerably better performance) on KVM, and in this post I describe how I did the installation on a NUC. …
I explain how I connected Node-RED with my Home Assistant (HASS), considering that they run on separate servers. They are deployed on different virtual machines, to allow independent maintenance and improve their performance. For your reference, I created another post here where I describe the Node-RED installation using Alpine and Docker underneath, running as a virtual machine on my KVM server. …
