What Are You Using Instead of NSX with Proxmox?

Curious what others are using as an NSX alternative with Proxmox. We're nearing the end of our VMware-to-Proxmox migration, and replacing NSX is the last major piece we haven't settled on yet. For those who have made the…

My VM is not Booting.

I am migrating Windows VMs from XCP-ng to Proxmox using Veeam Community Edition. Most of the migrated VMs initially failed to boot and were showing BSOD errors. To fix them, I booted into the Windows Recovery Environment…

A lot of kernel updates lately. Are there a lot of bugs/problems?

I've been updating kernels three or four times recently. They're a bit more involved for me than a simple update as I shut everything down, update and then start everything up again. Just curious.

Common questions on Proxmox, surfaced from across the indexed web.

Does macvlan work inside a Proxmox VM?

Yes, but the VM’s virtual network interface needs to be configured to pass VLAN tags. In Proxmox, this means the bridge the VM uses must be VLAN-aware, and the VM’s interface should either be on a trunk or have the specific VLAN tag set. See the Proxmox VLAN configuration guide for the full setup. If you’re just getting started with Docker in Proxmox, setting up Docker in Proxmox via a VM is worth reading first.

Will GPU passthrough work if I’m also running Home Assistant on the same Proxmox host?

It depends on whether your host has integrated graphics or a second GPU for the hypervisor. If the host can keep its own display adapter, other VMs like Home Assistant on Proxmox run independently and aren’t affected by the GPU being passed through to a different VM. Security note: IOMMU configuration and kernel parameters affect system-level isolation. Review any changes in the context of your threat model — especially allow_unsafe_interrupts, which weakens IOMMU isolation. Security best practices in this area continue to evolve.

Why Use Proxmox VE?

Proxmox VE is a free and open-source virtualization platform built on Debian. It supports KVM virtual machines, LXC containers, ZFS storage, clustering, backups, live migration, and high-availability features. For home labs, the big advantage is flexibility. You can run a Windows VM, a Linux server, Home Assistant, Docker, Pi-hole, Plex, Jellyfin, TrueNAS, or even pfSense on the same physical system. For small businesses or more advanced users, Proxmox can scale into multi-node clusters with shared storage and centralized management. The main tradeoff is that Proxmox is infrastructure software

Is Proxmox the Right Platform?

If you’re still comparing virtualization platforms, these guides are the best place to start: Proxmox vs ESXi Proxmox vs KVM Proxmox vs Hyper-V XCP-ng vs Proxmox Unraid vs Proxmox if you’re deciding between a NAS-focused OS and a hypervisor In general, I’d choose Proxmox if your main goal is virtualization. I’d choose Unraid or TrueNAS if your main goal is NAS storage, and virtualization is secondary. Proxmox can do storage, and NAS operating systems can run VMs, but picking the tool that matches your main use case usually leads to a better setup.
