Hello everyone, I moved my server to new hardware. With new IPv6 IP's. Now my Gateway looks like this: fe80:0000:0000:0000:0000:0000:0000:0001 My Proxmox Host can use IPv6 and I can ping outside, fine! :-) But my LXC Container can not use IPv6. LXC Container also use...

I noticed an issue where I was experiencing a lot of OOM errors within my LXC containers. After updating to Deb13/PVE9.x I found some of my LXC containers at 99% CPU and 99% MEM usage. Debian 13 has by default, moved /tmp to a tmpfs. It incorrectly pulls the amount of memory tmpfs has...

After updating to Proxmox 9.1, I noticed that ArchLinux is not listed in the list of LXC container templates in GUI page. However, it seems to be listed on http://download.proxmox.com/images/system/ . The same issue has also been raised in Reddit. Is this a mistake or has the ArchLinux...

Hello, I'm a bit confused when it comes to storage options for LXC containers. I want to move all of my disks to Truenas and migrate all disks there. In VM I can easily use ISCSI as backend storage, no issues here. But documentation on LXC containers also states that remote storages like ISCSI...

I recenty upgraded my Debian LXC running DNS and backups have started to fail. Here's a writeup of the investigation. What is the right way to address this? PVE 8.4.13 Issue:Automated backups of LXC container 101 (AdGuard2, Debian 11) started failing after running apt update && apt...

The reported memory usage of a VM in its summary and graphs includes RAM used by caching inside a VM. The reported memory usage of a node in its summary includes RAM used by caching inside VMs and LXCs. The reported memory usage of an LXC in its summary does not include RAM used by caching...

I finally got ZeroTier to launch inside an LXC and create the ztxxxxxx interface, and the container is joining the network fine. But I still can’t get forwarding/routing working so my remote ZeroTier clients can access anything on the Proxmox LAN. ZeroTier web UI my route is pushed, for my...

Ich habe seid einigen Tagen ein sehr interessantes Verhalten. Sobald ich im Debain 13 (Trixie) LXC Container bei `docker.io` IPv6 aktiviere, kann der LXC Container kein SLAAC mehr beziehen. Ich konnte schon durch Test Festellen, das wenn ich das gleiche mit Debian 12 (Bookworm) aktuell mache...

This morning I woke to find a number of my LXCs where not running some of the applications in their docker containers, and when I re-ran docker compose up -d I would get this error message for every docker instance in every LXC affected. "Error response from daemon: failed to create task for...

Be careful when updating Docker on Proxmox LXC machines (as far as I know): when you run apt update&&apt upgrade, among other packages, containerd.io is updated to 1.7.28-2~debian.13~trixie, so if you try to launch your containers, you will get the following error: So your containers aren't...

I have a few Proxmox clusters, all running a mix of LXCs and VMs. Most of them have their disks on Ceph, but some are on ZFS or LVM-thin. Almost all of the containers/VMs are running debian 12/13. I know how disk trimming works when it comes to VMs: - I enable the "discard" option of the...

Hi everyone, I'm running Proxmox VE 9.0.11 on a mini PC. I have an unprivileged LXC container (Ubuntu 24.04) hosting Jellyfin for media streaming. The container has a USB external HDD (NTFS) passed through as a bind mount: host /mnt/media -> LXC /mnt/media with uid=1005,gid=1005 for proper...

Hi folks! I'm struggling with some strange behavior where I'm attempting to mount some host file systems in the unprivileged guest containers. The reason why it's strange is because it's wildly inconsistent, even in the same guest. I've found several guides (One, Two) that follow the same set...

Hello all, I have a proxmox setup, which is pretty basic. Other than maybe some VirGL packages. However I get this error when I am trying to backup my LXC container: INFO: starting new backup job: vzdump --notes-template '{{guestname}}' --mailnotification failure --mode snapshot --node prox1...

Can't seem to get a static IP to take on one of my containers. I made sure the IP is not in use and I added etho and vmbr0, selected static and put in 192.168.111.80/24 and a gateway of 192.168.111.1 (my ASUS router). When I restart it, it pulls a DHCP address. I even tried adding a reservation...

Although i see ways to use a watchdog for VMs (eg https://forum.proxmox.com/threads/hardware-watchdog-at-a-per-vm-level.104051/), does anyone have any tips to doing so for a container? Ideally it would try a restart before a reset.

Today I fell victim to the "we're going to trash your installation" bug in the latest release of Jellyfin. I currently (or used to, anyway) run it in an LXC. Rather than jump through all the hoops Jellyfin say you need to do to take your system back to an earlier version, I thought it would be...

Hi, I am trying to set up a debian 13 LXC container on Proxmox 9.0.11 from which I can manage ZFS pools. I managed to bind the ZFS storage to the container, however, now I am struggling to get ZFS commands to work inside the container. When I try to use a ZFS command, I get zpool status Failed...

Hello, I've created an Immich LXC using the community helper scripts and it installs and runs root on the drive of your choosing. However, it doesn't give the option to mount external storage options during its initial setup. I'm wondering how I can add a different storage option for my actual...

Hallo liebes Forum, ich habe mir als Ablöse für Kodi einen Jellyfin LXC container mit dem Community-Script erstellt. Das klappt super. Jetzt wollt ich meine Media-USB-Platte in diesen Container einhängen. Hier gehen die Probleme los: Das Einhängen an sich funktioniert: mp0...
