Proxmox VE 8.4 is out – Why it’s the ultimate homelab choice

TL;DR

Proxmox VE 8.4 landed today, bringing live-migration for vGPU VMs, virtiofs host-to-VM file sharing, an official backup-plugin API, and a refreshed stack (QEMU 9.2, Ceph Squid 19.2.1, kernel 6.8/6.14).
Below you’ll find a quick look at what’s new and my top-10 reasons to pick Proxmox for a homelab in 2025.


What’s new in Proxmox VE 8.4

Feature Why it matters
Live migration with mediated devices Finally move vGPU-backed VMs between nodes without downtime – perfect for GPU-enabled homelab clusters.[^2^][^3^]
Virtiofs directory passthrough Share any host folder with a VM at near-native speed – no NFS/SMB hassle. Linux guests work out-of-the-box; Windows needs a small driver.[^2^][^3^]
Third-party backup API Veeam, Nakivo, or your own scripts can now hook natively into Proxmox’s backup scheduler, verification, and UI.[^2^][^3^]
Updated core stack Debian 12.10, kernel 6.8.12 (6.14 opt-in), QEMU 9.2.0, LXC 6.0.0, ZFS 2.2.7, Ceph Squid 19.2.1 stable.[^3^]
UI & SDN polish Tag-based grouping, firewall integration for VNets, new installer network presets.[^1^][^3^]

Top-10 reasons to choose Proxmox for your homelab

  1. 100 % free & open-source – no license keys, no feature gates.

  3. Killer clustering – create a 3-node HA cluster with shared Ceph storage in under an hour.
  4. Built-in ZFS & Ceph – snapshots, replication, self-healing, all out-of-the-box.
  5. Container-first – LXC with turnkey templates for Plex, Nextcloud, Docker, etc.
  6. GPU passthrough & vGPU – game, transcode, or ML on any VM.
  7. Backup server integration – deduplication, encryption, and now webhooks for custom alerts.[^1^]
  8. Virtiofs & 9p – lightning-fast host ↔ guest file shares without network overhead.
  9. Massive community – Reddit, forums, and thousands of Ansible roles to copy-paste.
  10. Runs on anything – from a 4-core Intel NUC to a 128 GB Ryzen mini-ITX beast.[^4^]

Closing thoughts
Proxmox VE 8.4 is the first release that truly feels enterprise-ready without the enterprise tax.
Whether you’re consolidating a rack of dusty towers or just need a single box to host Jellyfin + Home Assistant + a dozen LXCs, Proxmox keeps getting better while staying 100 % free.
Happy homelabbing!
