  1. format / reset rootfs disk in container

    Dear Community, When I provision a LXC container in Proxmox, it is quite difficult to reset it to an initial state. I want to override the rootfs with a clean image from the template and reinitialize the basic setup Proxmox does (like install SSH keys, configure network). The reason for this...
  2. Unable to boot Containers after update

    Hi! I did a normal "apt update" and all of a sudden my Containers stopped working. Then I noticed you guys had released a new version so I upgraded to 6.0. Still no luck. It's a little homeserver so I run the no-subscription. WebGUI won't start them, nor manually via CLI The error: lxc-start...

    Greetings all. This is my first time playing around Proxmox environment. Yesterday, I was trying to redo a Ceph pool storage and try to remove a container from the cluster that is connected to the Ceph pool storage. The container is a success, but then I encounter this problem where I cannot...
  5. Hyper-V Host > Proxmox Guest > LXC Container - cannot access network interface in container

    If I do a vanilla Proxmox install on bare metal, create an LXC container (using the Debian-10.0 standard template), I am able to set up eth0 as either static or DHCP within the container, and it bridges to my network without issue (I am able to ping it, ssh, etc.). If I do a vanilla Proxmox...
  6. LXC Options via API

    Hi, Is there a way to change the "low-level" LXC options via API? https://pve.proxmox.com/wiki/Linux_Container#_file_format I could not find any suitable options under path "/nodes/{node}/lxc/{vmid}/config". Thanks, Andreas
  7. Why my container is swapping?

    Hi, I have a container which has very slow performance, and trying to debug this i realised that it's swapping so much even if it has a lot of RAM memory available: These are the status graphs of the hypervisor: As you can see the host does not seems to be overloaded. Another...
  8. fstrim doesn't work in containers (any OS) - workarounds?

    Hi again I've been trying all day to get fstrim working inside unprivileged LXC containers with no luck. Initially I thought it was just a Debian/Ubuntu issue, but I've tried multiple OS templates and it always results in: FITRIM ioctl failed: Operation not permitted. FYI it works fine in...
  9. Is fstrim needed on LVM-thick containers?

    Hi all, I've just discovered that debian/ubuntu has a bug with running fstrim inside containers. However, I am not using LVM-thin, just regular LVM. Therefore my raw disk image size won't change when files are deleted or added. For this reason, I'm thinking maybe there's no need to run fstrim...
  10. API doc for automatic container rootfs initialization

    Hello! I'm using the REST API to create LXC containers, and one problem I had is that I could not find any documentation on how the rootfs parameter should be passed to have PVE to automatically create and format the root volume, and copy the template there. After some googling, I found on...
  11. Can't start container restored from backup - unable to detect OS distribution

    My single node Proxmox recently got very messed up. Gave up on it, killed it and reinstalled Proxmox from scratch (a couple of days ago - v. 5.4). I then restored containers from backups. However, one container (originally CT 100 and restoring to CT 100) does not start. That container had been...

  13. Need extra range for uid in unprivileged lxc containers

    Hi, I need to allow some bigger uid than the default one (65536) in LXC containers (eg. mine is >72000 and new users are >120000 in the LDAP). As i understand lxc.idmap definition (in UID MAPPINGS section of linux.container manpage), these lines (in /etc/pve/local/lxc/2100.conf file) should...

    Network Configuration for LXC Containers

    Hey all, So, I know you configure the network interfaces for new containers in the web interface (or by editing the corresponding config file in /etc/pve/lxc) but how does it work when you actually power up the container? The reason I ask is, I have a bunch of Ubuntu 14.04 based containers...

  20. Container's network erratic behavior...

    Hi! I installed Proxmox on a corporate environment in order to use it exclusively for managing containers (our VMs are already managed by VMWare...). The network is working, but I realize that my containers stop to respond to external pings for long periods of time, but not when I'm pinging...
