    LXC and Docker compatibility now

    I'm new to Proxmox, started to play a bit with, and currently loving it ! I'm using LXCs on a dedicated server to support various services for myself. Still, I have one that is using Docker (Affine.pro self-hosted setup is simpler with it). I saw some threads about using Docker under LXC not...

    Tool to shrink Proxmox VM and LXC disks

    Hi everyone, Since Proxmox doesn't leer disk from the GUI, Iwrote a Bash script that automates the whole process. It runs entirely on the host with the guest stopped, so there's no GParted or live-CD juggling. It handles the tricky parts (filesystem, partition table, and the underlying host...

    vzdump hookscript not triggered on one specific node (LXC), works fine on other nodes with identical config

    Hi, I'm running a 3-node PVE cluster (all on version 9.1.1, except one node on 9.1.4) and I'm facing an issue where the hookscript for vzdump is not being triggered at all on one specific node, while the exact same setup works perfectly on the other two. Cluster setup: Node A (proxmox)...

    [Workaround] PVE 9.2 / Ceph Tentacle: LXC containers fail to start with "rbd: sysfs write failed" — OSDs advertise v1-only public addr

    Posting this in case it helps others on PVE 9.2 + Ceph Tentacle, and to ask whether the underlying behavior is a bug. Full disclosure, I heavily relied on AI to troubleshoot and resolve (albeit with a workaround) and draft this post. After a cluster-wide cold boot, all my LXC containers backed...

    Configuring an LXC container cloned from a template via API

    I have an LXC container with some specialized configuration options which I have converted into a template. Now some users should be capable of cloning this template via the ProxMox API while performing some configuration options (like, setting an authorized SSH key). How can this be done? The...

    Unable to destroy LXC container after CloudPanel installation (Logical volume contains a filesystem in use)

    Hi all, Although we are fully aware that CloudPanel does not officially support LXC containers, one of our clients installed it inside a non-nested CT without our knowledge. This is completely out of our administrative control, and we are now passively dealing with the aftermath. The main...

    Configuring low level LXC options via API

    I want to create an LXC container on my PVE node and I need to set some low level options (like lxc.environment and lxc.hook.pre-start). It works fine if I SSH onto the node and edit the file /etc/pve/lxc/4711.conf manually . But since I need to integrate this into an automated workflow, I would...

    In Proxmox 9.2.3 what is this UI checkbox for?

    The checkbox is described as 'Host-Managed', it shows up when you edit a LXC guest's network interface: Unfortunately the Help page doesn't have any reference information for this checkbox.

    Hi, After all of the CVE's and security disclosures over the past week or two, I thought it'd be useful to upgrade my Proxmox nodes to the latest. I recently updated everything to PVE 9 & Ceph 19 and it has been working without fault for a few weeks. Since todays package updates, I am getting...

    My journey on LXC/CT, docker and GPU Passthrough

    Thought I would document this down in case anyone has tried to do this but again had no luck getting answers. TLDR: Use a VM for anything GPU/pass through related. The reason I was digging into this first was because I wanted to run a LLM on my local network but without a GUI. I wanted to save...
