Overview

Debian 11 LVM is the Debian 11 (bullseye) release cut with an LVM root layout: the root filesystem lives on a logical volume (debian-vg/root, the same naming the Debian installer's own guided LVM option produces) inside a volume group rather than on a fixed raw partition. There is no application layered on top: the operating system is the product. The LVM layout means you can extend the root volume onto a larger disk while the system is running, add new volumes for data or applications, and reshape storage with standard LVM tooling instead of being locked to the size and shape the image shipped with. Debian 11 left free Debian LTS on 31 August 2026: this image is patched to the final free archive state for bullseye and contains no Extended LTS content, which is a separate paid subscription from Freexian. Choose it when your estate is standardised on Debian 11; for a fresh deployment, choose Debian 12 LVM or Debian 13 LVM.

Why the cloudimg image

cloudimg builds the LVM layout from its own hardened Debian 11 base, patches it to the last packages the free Debian archive publishes for bullseye, verifies the layout is genuinely in place with a proven online grow, and hardens it before it ships. The end-of-LTS posture is verified rather than claimed: every repository on the image reports origin Debian, every installed version is one those repositories still offer, and the pruned Azure mirror the stock image ships is replaced with Debian's own hosts so the machine keeps a working package source. There is no default login: SSH access is by the key you supply at launch, password authentication is off and the root account is locked. Machine identity and SSH host keys are regenerated uniquely on every instance, and the image is backed by a paired deploy guide and 24/7 cloudimg support.

Common uses

  • Estates standardised on Debian 11 that need an LVM root under an existing, certified stack
  • Workloads migrating off bullseye that need a like-for-like base with room to grow storage online
  • Servers where storage will be reshaped later, adding volumes for data, logs or applications
