    "title": "VM passthrough vs LXC passthrough",
    "body": "LXC passthrough is <strong>not a raw block device</strong>. The container gets a <em>mount point</em> — i.e. a directory backed by a partition you pick on the host. Unlike a VM, the guest kernel is the host kernel, so the filesystem (ext4 / xfs / btrfs) is read and managed by Proxmox itself and then exposed to the container."

    "summary": "ProxMenux filters out the root disk, mounted disks, and disks already referenced by any VM/LXC config. Disks with active ZFS/LVM/RAID membership are hidden; stale signatures show a ⚠ label so you can wipe them before formatting."
