  • Regardless of VM or LXC, I would only install docker once. There’s generally no need to create multiple docker VMs/LXCs on the same host. Unless you have a specific reason; like isolating outside traffic by creating a docker setup for only public services.

    Backups are the same with VM or LXC on Proxmox.

    The main advantages of LXC that I can think of:

    • Slightly less resource overhead, but not much (debian minimal or alpine VM is pretty lightweight already).
    • Ability to pass-through directories from the host.
    • Ability to pass-through hardware acceleration from a GPU, without passing through the entire GPU.
    • Ability to change CPU cores or RAM while it’s running.
