Over three months after the previous major 9.0 release, Proxmox, a powerful, free, open-source virtualization platform with over 1.6 million installed hosts worldwide, unveiled the first update to the series, Proxmox Virtual Environment 9.1. The release builds on Debian 13.2 “Trixie” and ships with kernel 6.17.2, QEMU 10.1.2, LXC 6.0.5, ZFS 2.3.4, and Ceph Squid 19.2.3 under the hood.
One of the most notable additions is support for creating LXC containers from OCI images. Administrators can now pull standard OCI images from registries or upload them manually and use them directly as templates.
Depending on the image, Proxmox provisions either full system containers or lean application containers, the latter optimized for microservices with minimal overhead. Application containers also gain host-managed DHCP and configurable environment variables, improving deployment flexibility without requiring a full userspace network stack.
