Proxmox Server Solutions has released the new version of its virtualization platform, Proxmox Virtual Environment (VE) 8.3, establishing itself as a key solution in modernizing corporate IT infrastructures. With over 1.3 million installed hosts worldwide, this open-source tool promises to improve the efficiency, security, and scalability of virtualization environments.
Proxmox VE 8.3, based on Debian 12.8, uses Linux kernel 6.8 by default, although it allows users to opt for kernel 6.11 to access the latest features. Additionally, it incorporates cutting-edge technologies such as QEMU 9.0.2, LXC 6.0, and ZFS 2.2.6, reinforcing its position as a leader in innovation.
Among the most important improvements in this version is the integration of the SDN stack with the firewall, which allows for the automatic generation of IP sets for virtual networks and virtual guests through the IP address management plugin. Furthermore, the new nftables-based firewall enables filtering of network traffic at both the host and virtual network level, restricting specific types of traffic such as SNAT or interzone communication.
The notification system has received a significant update, adding support for webhooks. This allows notifications to be sent via HTTP requests to external services, facilitating integration with third-party tools. Additionally, the new tagging view in the resource tree organizes and groups virtual guests by tags, simplifying the management of large-scale environments.
Another notable update is the compatibility with Ceph Squid 19.2.0, along with Ceph Reef 18.2.4 and Ceph Quincy 17.2.7. Proxmox VE 8.3 enables administrators to choose the version of Ceph during installation, enhancing flexibility in storage configurations. Moreover, container backup processes have been optimized to identify unchanged files and reduce processing time for backups made on Proxmox BackupA backup is a security copy created and stored… Server.
Migrating from other hypervisors has also been simplified. Users can now directly import OVF and OVA files from storage via the web interface or from a URL. This, combined with an import wizard, makes transitioning from platforms like VMware to this open-source solution easier.
According to Thomas Lamprecht, CTO of Proxmox, “Our virtualization platform is designed to empower businesses with unmatched efficiency and control. The integration of advanced software-defined networking capabilities simplifies IT infrastructure, enhances agility, and fosters scalable growth.”
Tim Marx, COO of Proxmox, highlighted the recent growth of the project: “In recent months, we have added 300,000 active hosts, reaching a total of 1.3 million. Our commitment to quality and value has resonated strongly, and we are excited to continue building on this momentum.”
David Carrero, cloud infrastructure expert and co-founder of Stackscale (Grupo Aire), noted that “Proxmox continues to be a benchmark in enterprise environments due to its robustness, flexibility, and ease of use. The capability to manage both software-defined networks and advanced storage options with Ceph makes it a powerful solution for companies seeking to optimize their infrastructure without relying on proprietary solutions.” Carrero also emphasized the value of Proxmox’s subscription support model: “Offering specialized technical support and access to enterprise repositories adds significant value for organizations that need to ensure the stability of their IT environments.”
Proxmox VE 8.3 is now available for download on the official Proxmox website.

Updates from previous versions can be easily performed using the APT package manager. For companies seeking additional support, Proxmox offers a subscription model with access to the enterprise repository and technical support, starting at 110 euros per year per CPU.
With an active user base of nearly 200,000 community members and available in 30 languages, Proxmox VE continues to stand out as a cost-effective alternative to proprietary solutions, allowing companies to modernize their infrastructures and transform their data centers into software-defined environments.
