When a workload runs slow and the CPU looks bored, the bottleneck is almost always storage. Inside a virtual machine, that storage is another layer of software on top of someone else’s storage, so guessing gets you nowhere. This guide shows you, step by step, how to benchmark storage performance inside a VM with fio … Read more

That TASK ERROR: KVM Not Supported message in Proxmox is frustrating, especially when you know your CPU should support virtualization. I have hit this exact error twice in my lab, and each time the fix was a combination of one BIOS toggle and two Linux commands. This guide walks you through everything I learned, so … Read more

If you have ever wanted to run a Windows gaming VM with near-native graphics, hand a workstation-class GPU to a Linux container, or isolate a GPU-intensive workload from your Proxmox host, you need GPU passthrough. On Proxmox VE 9, that process is more reliable than it has ever been, but only if IOMMU is enabled … Read more

I learned this the hard way. After a routine apt dist-upgrade rebooted my home lab into kernel 6.14, my gaming VM refused to start, my host froze solid twice, and my ZFS pool suspended itself when I tried to reset the GPU. If your Proxmox GPU passthrough kernel update fix is what you are looking … Read more

I run my home lab on a Dell R720 with TrueNAS SCALE virtualized under Proxmox, and the single biggest unlock was passing an LSI HBA through to the VM. In this guide I’ll walk you through how to virtualize TrueNAS SCALE under Proxmox with an HBA passed through, so the VM gets direct control of … Read more

If you spin up more than a couple of Linux VMs a year, building each one by hand wastes hours. I learned this the hard way running a homelab where every Kubernetes node, every CI runner, and every test box started as a fresh Ubuntu install. Setting up an Ubuntu cloud-init template on Proxmox is … Read more

Proxmox Backup Server (PBS) is a deduplicating backup solution that stores compressed, encrypted snapshots of your VMs and containers so you can restore them to any node in minutes. In this guide, our team walks through every step of creating backups, scheduling them, restoring individual files or entire machines, and backing up your Proxmox host … Read more

Nothing ruins a Monday morning faster than a Proxmox node that hangs at the boot splash screen, then drops you into a recovery shell because the rpool went degraded overnight. We have hit this exact scenario in our own homelab and on customer clusters, and the good news is that you can rebuild full redundancy … Read more

I have run into this exact problem more times than I can count. A Zigbee stick works fine for weeks, then a host reboot silently swaps it with a second stick and Home Assistant stops seeing the right device. This guide is the workflow I now use to make Proxmox USB passthrough survive every reboot. … Read more

Setting up a three-node Proxmox cluster with quorum and live migration gives you the smallest reliable topology for true high availability in Proxmox VE. In this guide I walk you through the exact configuration I use in my own homelab and small production environments, from network planning and cluster creation to quorum tuning and a … Read more
