+
+Then run it:
+
+```bash
+sudo netselect-apt -c US -a amd64 -n stable

+# Fix APIPA (veth)
+
+## Problem
+
+On Debian 11, when:
+
+1. Using docker containers that use the `host` network mode.
+2. `PreferredTechnologies` is set to `ethernet,[...]` in `/etc/connman/main.conf`.
+   - This may not be a problem when ethernet is plugged in, not just wifi.
+
+The system **uses a veth interface** to connect to the internet, which uses an APIPA (169.254.*.*) IP address, so the system can only contact devices on the LAN.
+
+## Solution
+
+Edit `/etc/connman/main.conf` and uncomment the line `# NetworkInterfaceBlacklist = vmnet,vboxnet,virbr,ifb,ve-,vb-`
+
+Result:
+
+```conf
+NetworkInterfaceBlacklist = vmnet,vboxnet,virbr,ifb,ve-,vb-

+# Move Docker program data

+Docker stores all its data in `/var/lib/docker` by default. This is usually fine, but this directory grows quickly, so we'll move it to `/mnt/big-stuff/docker-program-data/`
+
+Edit `/lib/systemd/system/docker.service` and add the `--data-root` option to the ExecStart line:
+
+```sh
+ExecStart=/usr/bin/dockerd --data-root /mnt/big-stuff/docker-program-data/ -H fd:// $DOCKER_OPTS

+# Resource limits
+
+You can limit the amount of CPU and/or memory resources that a container can use.
+
+## CPU
+
+| Option | Description |
+|--------|-------------|
+| `--cpus` | Set number of CPUs thee container can use |
+| `--cpu-period` | Limits the length of time it can schedule the CPU before being throttled (used alongside `--cpu-quota`) |
+| `--cpu-quota` | The throttling setting activated when the CPU is scheduled longer than `--cpu-period` |
+| `--cpuset-cpus` | Limit the container to specific CPUs or cores (e.g. 0-3, 0,1) |
+| `--cpu-shares` | The number of relative shares of the CPU the container can use (default 1024) |
+
+## Memory
+
+A markdown table:
+
+| Option | Description |
+|--------|-------------|
+| `-m` or `--memory` | Memory limit (minimum 6m (megabytes)) |
+| `--memory-swap` | How much swap is available - [details](https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details) |
+| `--memory-swappiness` | "By default, the host kernel can swap out a percentage of anonymous pages used by a container. You can set --memory-swappiness to a value between 0 and 100, to tune this percentage" - [details]() |
+| `--memory-reservation` | Soft limit less than `--memory` (for when there is low memory on host), *soft* limit, so usage may exceed this. |
+| `--oom-kill-disable` | Disable OOM Killer (stops from killing container processes when out-of-memory error occurs) - Make sure to use `-m`, or host processes could be killed |
+
+## Example
+
+Note: `--xxxx 4` in `docker run` would be replaced with `xxxx` in `docker-compose.yml`. See below:
+
+```yml
+service:
+  image: nginx
+  mem_limit: 512m
+  mem_reservation: 128M

+# Restart Policies
+
+Restart policies control whether and how Docker attempts to restart a container.
+
+| option | description |
+| ------ | --- |
+| no | does not restart automatically |
+| on-failure[:max-retry] | restarts only when the container exits with a non-zero exit code, and when it has been restarted fewer than max-retry times. |
+| always | always restarts the container if it stops. If it is manually stopped, it is restarted only when Docker daemon restarts or the container itself is manually restarted. |
+| unless-stopped - always restarts the container unless it is manually stopped. Does not restart when the docker daemon is restarted. |
+
+If no restart policy is provided, the default is no.

+## Example

+# Nvidia 470 datacenter drivers
+
+**Note:** Desktop drivers and datacenter drivers are different.
+
+## Debian
+
+This hasn't yet been tested. If you have tested it, please open a PR to update this section.
+
+### Add apt repos
+
+**You can skip this if you already have the repositories enabled**
+To add the non-free and contrib repos, edit `/etc/apt/sources.list` and add `non-free contrib` to the end of each line, like this:
+
+```txt
+deb http://deb.debian.org/debian/ bullseye main non-free contrib
+deb-src http://deb.debian.org/debian/ bullseye main non-free contrib
+```
+
+Then, run `apt update`
+
+### Installation
+
+To install the driver:
+
+```sh
+apt install nvidia-tesla-470-driver
+```
+
+And to install CUDA:
+
+```bash
+apt install nvidia-cuda-dev nvidia-cuda-toolkit
+```
+
+### Links
+
+- [Driver Install Guide](https://wiki.debian.org/NvidiaGraphicsDrivers) ([Internet Archive Link](https://web.archive.org/web/20221123184836/https://wiki.debian.org/NvidiaGraphicsDrivers))
+
+## Fedora
+
+This guide uses the RPM Fusion repositories, and if you install CUDA, it uses Nvidia repositories as well. Note that this guide is only compatible with Fedora 35+, I'm not sure about RHEL versions.
+
+### Add RPM Fusion repository
+
+**You can skip this if you already have the repository installed.**
+
+To add the RPM Fusion repository:
+
+```bash
+# Add gpg key
+sudo dnf install distribution-gpg-keys
+sudo rpmkeys --import /usr/share/distribution-gpg-keys/rpmfusion/RPM-GPG-KEY-rpmfusion-free-fedora-$(rpm -E %fedora)
+# Add repo with gpg check
+sudo dnf --setopt=localpkg_gpgcheck=1 install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
+```
+
+### Install Driver
+
+First, update everything, and reboot if you're not on the latest kernel.
+
+```bash
+dnf update -y
+```
+
+Then, install the driver:
+
+```bash
+dnf install akmod-nvidia-470xx
+```
+
+_**Do not reboot yet.**_
+
+Before rebooting, use `top` or `ps` to make sure there is no `akmods`, `cc*`, `kthreadd`, or `gcc*` process running (`*` is either nothing or a number)—or anything using tons of CPU that you don't expect.
+
+*Note:* `nvidia-smi` and other tools are not included with the driver. For that, you need to install CUDA.
+
+### Install CUDA
+
+Install packages needed for CUDA with:
+
+```bash
+export FEDORA_VERSION=$(rpm -E %fedora) # Nvidia's repo doesn't support Fedora 38 yet, so change this to 37 if you're on Fedora 38
+dnf config-manager --add-repo https://developer.download.nvidia.com/compute/cuda/repos/fedora35/x86_64/cuda-fedora${FEDORA_VERSION}.repo
+dnf clean all
+dnf module disable nvidia-driver
+dnf -y install cuda
+```
+
+*Note:* Don't re-enable `nvidia-driver`
+
+### Problems
+
+#### Suspend Issues
+
+I had issues with my K80 not working after being suspended. For example, `torch.cuda.is_available()` would give an error and return False, rather than saying True.
+To fix this, install `xorg-x11-drv-nvidia-470xx-power`
+
+```bash
+dnf install xorg-x11-drv-nvidia-470xx-power
+```
+
+---
+
+#### CUDA is higher version than driver
+
+Sometimes the driver in the CUDA repo, and therefore dependencies for CUDA are of a later version than the driver. To fix this, run:
+
+```bash
+dnf module enable nvidia-driver -y && dnf download cuda-drivers && dnf module disable nvidia-driver -y
+rpm -Uvh cuda-drivers*.rpm --nodeps
+dnf update
+```
+
+### More stuff
+
+Why not install `xorg-x11-drv-nvidia-470xx`?
+
+- That's the _display_ driver, not the data center driver. It is the same version number, but is not the same.

+# Spice Guest Tools
+
+These are the software packages for the guest OS that provide stuff like copy-paste, shared folders, graphics drivers, etc. They're not required, but are quite useful (and tiny!)
+
+## Windows
+
+The download is [here](https://www.spice-space.org/download/windows/spice-guest-tools/spice-guest-tools-latest.exe), it's easy. Just install it and restart.
+
+## Linux
+
+Linux guests use the packages `spice-vdagent` (for copy-paste, shared folders, etc.) and `xf86-video-qxl` (for graphics drivers) (or `xf86-video-qxl-devel` if you're building from source, according to GitHub copilot, IDK). The `spice-vdagent` package is available in most distributions' repositories, but the `xf86-video-qxl` package is not. You can build it from source (download [here](https://www.spice-space.org/download.html)).
+
+## macOS
+
+No. Maybe the Linux ones would work, IDK. I don't feel like testing it. Check out [this](https://github.com/utmapp/UTM/discussions/3772) and [this](https://docs.getutm.app/).
