Proxmox VE 8.4 is now available for download. It is built on Debian 12.10 "Bookworm" and utilizes Linux kernel 6.8.12, with kernel 6.14 available as an opt-in option. The release encompasses features including live migration with mediated devices, an API for third-party backup solutions, and virtiofs directory passthrough. Live migration enables the segmentation of active virtual machines (VMs) into various virtual devices, including NVIDIA vGPU. The newly introduced 'pve-nvidia-vgpu-helper' tool streamlines the configuration process for NVIDIA vGPU drivers. The release additionally features updates to the most recent versions of prominent open-source technologies for virtual environments, including QEMU 9.2.0, LXC 6.0.0, ZFS 2.2.7, and Ceph Squid 19.2.1. Additional enhancements cover more resilient backup solutions, advancements in the software-defined networking framework, and expanded options within the ISO installer.
Proxmox VE 8.4 released!
We are excited to announce that our latest software version 8.4 for Proxmox Virtual Environment is now available for download. This release is based on Debian 12.10 "Bookworm" but uses the Linux kernel 6.8.12 and kernel 6.14 as opt-in, QEMU 9.2.0, LXC 6.0.0, ZFS 2.2.7 with compatibility patches for kernel 6.14, and Ceph Squid 19.2.1 as stable option.
Highlights in Proxmox VE 8.4
- Live migration with mediated devices: Mediated devices allow physical hardware resources to be partitioned into multiple virtual devices. It is now possible to migrate running virtual machines (VMs) which have mediated devices such as NVIDIA vGPU in use. Within a cluster, live migration to another node is possible if hardware and driver support for live migration is equally available on the target node. An available platform with support for live migration is NVIDIA vGPU. Additionally, the new ‘pve-nvidia-vgpu-helper’ tool simplifies the setup of NVIDIA vGPU drivers.
- API for third-party backup solutions: Proxmox VE now provides an API simplifying the development of plugins by external backup solution providers. Third party backup solutions can now directly implement backup and restore functionalities in Proxmox VE, and make use of advanced features. Third-party backup providers can implement a plugin that is fully integrated in the backup stack and in the web interface of Proxmox VE. This gives third-party backup solutions the opportunity to enhance the efficiency, reliability, and manageability of their backup and restore features in Proxmox VE.
- Virtiofs directory passthrough: Version 8.4 offers the functionality to share files and directories directly between a host and the VMs running on that host. This is achieved through the use of virtiofs, which allows VM guests to access host files and directories without the overhead of a network file system. Modern Linux guests support virtiofs out of the box while Windows guests need additional software to use this feature.
- Latest versions of open-source technologies: Proxmox VE 8.4 is based on Debian 12.10 (“Bookworm”), but uses the Linux kernel 6.8.12 as stable default and the newer kernel 6.14 as opt-in. This version of Proxmox VE includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 9.2.0, LXC 6.0.0, ZFS 2.2.7 with compatibility patches for kernel 6.14, and Ceph Squid 19.2.1 as stable option.
Further enhancements include more robust backup fleecing, improvements in the software-defined networking (SDN) stack, and additional options in the ISO installer.
