Install LXD on an Ubuntu server and pass all NVIDIA GPUs into LXD system containers via CDI — install snapd+LXD (snap), run `lxd init` with a ZFS or dir storage pool, set up a host CDI spec at /etc/cdi and wire the nvidia-container-toolkit auto-refresh units so it stays fresh across driver upgrades, and grant every GPU to every instance through the default profile, then verify nvidia-smi inside a container. Use when asked to install or set up LXD/lxc on a GPU host, give LXD containers GPU…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Ubuntu LXD GPU Server Install LXD on an Ubuntu host and expose **all** NVIDIA GPUs to LXD system containers via **CDI**, granted through the `default` profile so every instance inherits them. Assumes the host driver + `nvidia-container-toolkit` (`nvidia-ctk`) are already in place — if not, run the **`ubuntu-nvidia-gpu-enablement`** skill first. ⚠️ **Use CDI, not `nvidia.runtime=true`.** LXD's legacy libnvidia-container hook hangs at container start with `nvidia-container-cli: initialization error: driver rpc error: timed out` on recent kernels / Blackwell GPUs. CDI uses the host's `nvidia-ctk` and a static spec — no driver RPC, no timeout. (Why: [REFERENCE.md](REFERENCE.md) §4.) ## Quick start ```bash # 1. install LXD + wire all GPUs into the default profile. Storage: zfs:<pool>/lxd | dir | zfs-loop:50GiB sudo LXD_STORAGE=zfs:rpool/lxd bash scripts/install-lxd.sh # 2. verify a fresh container sees every GPU (launches a throwaway container, asserts the count, cleans up) bash scripts/verify-gpu.sh ``` ## Pre-flight - Sudo user (SSH fine). `nvidia-smi -L` lists the GPUs on the **host**. …

How to install
mdr add soulmachine/skills/ubuntu-lxd-gpu-server@sha256:8a9433a53f910f5dThe line at the top of this page pins the label git:20260611.6bfa5f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
