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^] |

If you run Ceph Reef (18.x) you can non-disruptively upgrade to Squid (19.x) through the GUI → Ceph → Upgrade.
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!
