 |Version|Date|Notes|
 |---|---|---|
+|   |2021-04-18|Add LIBGUESTFS debug & trace commands, exit on fail when creating bootdisks. Silence touch errors.| 
+|4.3|2021-03-24|Enable interactive QEMU again. Remove envsubst since we are already using bash... Add set -x flag| 
+|4.2|2021-03-24|Add all ENV variables to each dockerfile for readability. Add RAM allocation buffer and cache drop bug fix. Add kvm and libvirt groups. Add `IMAGE_FORMAT=qcow2` to allow `IMAGE_FORMAT=raw` too.|
+|   |2021-03-19|Use RAM=3 as the default RAM allocation. Add instructions to clear buff/cache.|
+|   |2021-03-17|Add RAM=max and RAM=half to dynamically select ram at runtime (DEFAULT).|
+|   |2021-03-06|Change envs to require --envs. Automatically enable --envs if --output-env is used. Same for plists, bootdisks. Fix help ugliness and sanity of generate serial scripts. Fix bootdisk not getting written to persistent file when using NOPICKER=true. NOPICKER=true is overridden by a custom plist now anyway. Remove useless case statements. Allow -e HEADLESS=true as human readable alternative to -e DISPLAY=:99.|
+|4.1|2021-03-04|Add `-e MASTER_PLIST_URL` to all images to allow using your own remote plist.|
+|   |2021-03-03|Add `WIDTH` and `HEIGHT` to set the x and y resolutions, use in conjuction with serial numbers.|
+|   |2021-03-02|Add ADDITIONAL_PORTS, for example `-e ADDITIONAL_PORTS='hostfwd=tcp::23-:23,'`|
 |4.0|2021-02-27|Add big-sur support. Use `sickcodes/docker-osx:big-sur` or build using `--build-arg VERSION=11`|
 |   |2021-02-26|Change `-e NOPICKER=true` to simply do `sed -i '/^.*InstallMedia.*/d' Launch.sh` and `export BOOTDISK=/home/arch/OSX-KVM/OpenCore-Catalina/OpenCore-nopicker.qcow2`.|
 |3.2|2021-02-25|Add a script to generate unique machine serial numbers. Add a script to generate a bootdisk from given serial numbers. Add Linux for libguestfs which allows the docker container to make QEMU bootdisks with specific serial numbers.|

-This starts a container with an existing installation. This special auto image was made by @sickcodes:
+### Professional support
 
-- SSH enabled
-- username is `user`
-- password is `alpine`
-- auto-updates off
+For more sophisticated endeavours, we offer the following support services:
 
-You will need around *50GB* of space to run this image: half for the base image + half for your runtime image.
+- Enterprise support, business support, or casual support.
+- Custom images, custom scripts, consulting (per hour available!)
+- One-on-one conversations with you or your development team.
 
-If you run out of space, you can delete all your old Docker images/history/cache by simply deleting `/var/lib/docker`, and restarting `dockerd`.

+## Initial setup
+Before you do anything else, you will need to turn on hardware virtualization in your BIOS. Precisely how will depend on your particular machine (and BIOS), but it should be straightforward.
+
+Then, you'll need QEMU and some other dependencies on your host:
 
 ```bash
-# find last container
-docker ps -a
+# ARCH
+sudo pacman -S qemu libvirt dnsmasq virt-manager bridge-utils flex bison iptables-nft edk2-ovmf
 
-# docker start old container with -i for interactive
-docker start -i containerid
+# UBUNTU DEBIAN
+sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager
 
+# CENTOS RHEL FEDORA
+sudo yum install libvirt qemu-kvm
 ```
 
-# Quick Start Own Image (naked container image)
-
-This is my favourite container. You can supply an existing disk image as a docker command line argument.
+Then, enable libvirt and load the KVM kernel module:
 
-Supply your own local image with `-v "${PWD}/mac_hdd_ng.img:/image"` and use `sickcodes/docker-osx:naked`
+```bash
+sudo systemctl enable --now libvirtd
+sudo systemctl enable --now virtlogd
 
-- Naked image is for booting any existing .img file.
-- By default, this image has a variable called `NOPICKER` which is `"true"`. This skips the disk selection menu. Use `-e NOPICKER=false` or any other string than the word `true` to enter the boot menu. This lets you use other disks instead of skipping the boot menu, e.g. recovery disk or disk utility.
+echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs
 
-```bash
-docker pull sickcodes/docker-osx:naked
+sudo modprobe kvm
+```
 
-# run your own image + SSH
-# change mac_hdd_ng.img
-docker run -it \
-    --device /dev/kvm \
-    -p 50922:10022 \
-    -v "${PWD}/mac_hdd_ng.img:/image" \
-    -v /tmp/.X11-unix:/tmp/.X11-unix \
-    -e "DISPLAY=${DISPLAY:-:0.0}" \
-    sickcodes/docker-osx:naked
+## Additional boot instructions for when you are [creating your container](#container-creation-examples)

-    --device /dev/kvm \
-    -p 50922:10022 \

+`$DISPLAY` is the shell variable that refers to your X11 display server.
 
-# Autoboot into OSX after you've installed everything
+`${DISPLAY}` is the same, but allows you to join variables like this:
 
-You can use `-e NOPICKER=true`.
+- e.g. `${DISPLAY}_${DISPLAY}` would print `:0.0_:0.0`
+- e.g. `$DISPLAY_$DISPLAY`     would print `:0.0`
 
-Old machines:
+...because `$DISPLAY_` is not `$DISPLAY`
 
-```bash
-# find you containerID
-docker ps
+`${variable:-fallback}` allows you to set a "fallback" variable to be substituted if `$variable` is not set.
 
-# move the no picker script on top of the Launch script
-# NEW CONTAINERS
-docker exec containerID mv ./Launch-nopicker.sh ./Launch.sh
+You can also use `${variable:=fallback}` to set that variable (in your current terminal).
 
-# VNC-VERSION-CONTAINER
-docker exec containerID mv ./Launch-nopicker.sh ./Launch_custom.sh
+In Docker-OSX, we assume, `:0.0` is your default `$DISPLAY` variable.
 
-# LEGACY CONTAINERS
-docker exec containerID bash -c "grep -v InstallMedia ./Launch.sh > ./Launch-nopicker.sh
-chmod +x ./Launch-nopicker.sh
-sed -i -e s/OpenCore\.qcow2/OpenCore\-nopicker\.qcow2/ ./Launch-nopicker.sh
-"
+You can see what yours is
+
+```bash
+echo $DISPLAY
 ```
 
-# Requirements: KVM on the host
-Need to turn on hardware virtualization in your BIOS, very easy to do.
+That way, `${DISPLAY:-:0.0}` will use whatever variable your X11 server has set for you, else `:0.0`
 
-Then have QEMU on the host if you haven't already

-```bash
-# ARCH

See also: [here](https://github.com/sickcodes/Docker-OSX/issues/188), [here](https://github.com/sickcodes/Docker-OSX/pull/189).
+
+For example (below) the `buff/cache` already contains 20 Gigabytes of allocated RAM:
+
+```console
+[user@hostname ~]$ free -mh
+               total        used        free      shared  buff/cache   available
+Mem:            30Gi       3.5Gi       7.0Gi       728Mi        20Gi        26Gi
+Swap:           11Gi          0B        11Gi
+```
+
+Clear the buffer and the cache:
+
+```bash
+sudo tee /proc/sys/vm/drop_caches <<< 3
+```
+
+Now check the RAM again:
+
+```console
+[user@hostname ~]$ free -mh
+               total        used        free      shared  buff/cache   available

-* Shut down the VM and copy out the qcow image with `docker cp stoppedcontainer:/home/arch/OSX-KVM/mac_hdd_ng.img .`
-* Run `qemu-img check -r all mac_hdd_ng.img` to fix any errors.

-* OPTIONAL: Run `qemu-img convert -c -O qcow2 deduped.img compressed.img` to further compress the image. This may reduce the runtime speed though, but it should reduce the size by roughly 25%.

-## What is `${DISPLAY:-:0.0}`?
+## Container creation examples
 
-`$DISPLAY` is the shell variable that refers to your X11 display server.
+#### Quick Start your own image (naked container image)
 
-`${DISPLAY}` is the same, but allows you to join variables like this:
+This is my favourite container. You can supply an existing disk image as a Docker command line argument.
 
-- e.g. `${DISPLAY}_${DISPLAY}` would print `:0.0_:0.0`
-- e.g. `$DISPLAY_$DISPLAY`     would print `:0.0`
+- Pull images out using `sudo find /var/lib/docker -size +10G | grep mac_hdd_ng.img`
 
-...because `$DISPLAY_` is not `$DISPLAY`
+- Supply your own local image with the command argument `-v "${PWD}/mac_hdd_ng.img:/image"` and use `sickcodes/docker-osx:naked` when instructing Docker to create your container.
 
-`${variable:-fallback}` allows you to set a "fallback" variable to be substituted if `$variable` is not set.
+  - Naked image is for booting any existing .img file, e.g in the current working directory (`$PWD`)
+  - By default, this image has a variable called `NOPICKER` which is `"true"`. This skips the disk selection menu. Use `-e NOPICKER=false` or any other string than the word `true` to enter the boot menu.
 
-You can also use `${variable:=fallback}` to set that variable (in your current terminal).
+    This lets you use other disks instead of skipping the boot menu, e.g. recovery disk or disk utility.
 
-In Docker-OSX, we assume, `:0.0` is your default `$DISPLAY` variable.
+```bash
+docker pull sickcodes/docker-osx:naked
+
+# run your own image + SSH
+# change mac_hdd_ng.img
+docker run -it \
+    --device /dev/kvm \
+    -p 50922:10022 \
+    -v "${PWD}/mac_hdd_ng.img:/image" \
+    -v /tmp/.X11-unix:/tmp/.X11-unix \
+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+    sickcodes/docker-osx:naked
+
+# run local copy of the auto image + SSH + Boot menu
+docker run -it \
+    --device /dev/kvm \
+    -p 50922:10022 \
+    -v "${PWD}/mac_hdd_ng_auto.img:/image" \
+    -v /tmp/.X11-unix:/tmp/.X11-unix \
+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+    -e "NOPICKER=false" \
+    sickcodes/docker-osx:naked
+```
+
+### Building an OSX container with video output
+
+The Quick Start command should work out of the box, provided that you keep the following lines. Works in `auto` & `naked` machines:
+
+```
+    -v /tmp/.X11-unix:/tmp/.X11-unix \
+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+```
+
+#### Download the image manually and use it in Docker 
+
+[![https://img.shields.io/docker/image-size/sickcodes/docker-osx/naked?label=sickcodes%2Fdocker-osx%3Anaked](https://img.shields.io/docker/image-size/sickcodes/docker-osx/naked?label=sickcodes%2Fdocker-osx%3Anaked)](https://hub.docker.com/r/sickcodes/docker-osx/tags?page=1&ordering=last_updated)
+
+
+This is a particularly good way for downloading the container, in case Docker's CDN (or your connection) happens to be slow.
 
-You can see what yours is
 ```bash
-echo $DISPLAY
+wget https://images2.sick.codes/mac_hdd_ng_auto.img
+
+docker run -it \
+    --device /dev/kvm \
+    -p 50922:10022 \
+    -v "${PWD}/mac_hdd_ng_auto.img:/image" \
+    -v /tmp/.X11-unix:/tmp/.X11-unix \
+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+    sickcodes/docker-osx:naked
 ```
-Hence, `${DISPLAY:-:0.0}` will use whatever variable your X11 server has set for you, else `:0.0`
 
-## What is `-v /tmp/.X11-unix:/tmp/.X11-unix`?
+#### Prebuilt image with arbitrary command line arguments 
 
-`-v` is a Docker command-line option that lets you pass a volume to the container.

-The directory that we are letting the Docker container use is a X server display socket.
+```bash
+docker pull sickcodes/docker-osx:auto
 
-`/tmp/.X11-unix`
+# boot to OS X shell + display + specify commands to run inside OS X!
+docker run -it \
+    --device /dev/kvm \

+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+    -e "OSX_COMMANDS=/bin/bash -c \"pwd && uname -a\"" \
+    sickcodes/docker-osx:auto
 
-If we let the Docker container use the same display socket as our own environment, then any applications you run inside the Docker container will show up on your screen too! [https://www.x.org/archive/X11R6.8.0/doc/RELNOTES5.html](https://www.x.org/archive/X11R6.8.0/doc/RELNOTES5.html)
+# Boots in a minute or two!
+```
+
+### Further examples
+
+There's a myriad of other potential use cases that can work perfectly with Docker-OSX, some of which you'll see below!
+
+### Building a headless OSX container
+
+For a headless container, **remove** the following two lines from your `docker run` command:
+
+```
+    # -v /tmp/.X11-unix:/tmp/.X11-unix \
+    # -e "DISPLAY=${DISPLAY:-:0.0}" \
+```
+
+#### Building a headless container from a custom image 
+
+[![https://img.shields.io/docker/image-size/sickcodes/docker-osx/naked?label=sickcodes%2Fdocker-osx%3Anaked](https://img.shields.io/docker/image-size/sickcodes/docker-osx/naked?label=sickcodes%2Fdocker-osx%3Anaked)](https://hub.docker.com/r/sickcodes/docker-osx/tags?page=1&ordering=last_updated)
+
+This is particularly helpful for CI/CD pipelines.
+
+```bash
+# run your own image headless + SSH
+docker run -it \
+    --device /dev/kvm \
+    -p 50922:10022 \
+    -v "${PWD}/mac_hdd_ng.img:/image" \
+    sickcodes/docker-osx:naked
+```
+
+### Building a headless container which allows insecure VNC on localhost (!for local use only!)
+
+**Must change -it to -i to be able to interact with the QEMU console**
+
+**To exit a container using -i you must `docker kill <containerid>`. For example, to kill everything, `docker ps | xargs docker kill`.**
+
+Native QEMU VNC example
+
+```bash
+docker run -i \
+    --device /dev/kvm \
+    -p 50922:10022 \
+    -p 5999:5999 \
+    -v /tmp/.X11-unix:/tmp/.X11-unix \
+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+    -e EXTRA="-display none -vnc 0.0.0.0:99,password" \
+    sickcodes/docker-osx:big-sur
+
+# type `change vnc password` into the docker terminal and set a password
+# connect to localhost:5999 using VNC
+```
+
+**NOT TLS/HTTPS Encrypted at all!**
+
+Or `ssh -N [email protected] -L  5999:127.0.0.1:5999`, where `1.1.1.1` is your remote server IP.
+
+(Note: if you close port 5999 and use the SSH tunnel, this becomes secure.)
+
+### Building a headless container to run remotely with secure VNC
+
+Add the following line:
+
+`-e EXTRA="-display none -vnc 0.0.0.0:99,password"`
+
+In the Docker terminal, press `enter` until you see `(qemu)`.
+
+Type `change vnc password`
+
+You also need the container IP: `docker inspect <containerid> | jq -r '.[0].NetworkSettings.IPAddress'`
+
+Or `ip n` will usually show the container IP first.
+
+Now VNC connect using the Docker container IP, for example `172.17.0.2:5999`
+
+Remote VNC over SSH: `ssh -N [email protected] -L  5999:172.17.0.2:5999`, where `1.1.1.1` is your remote server IP and `172.17.0.2` is your LAN container IP.
+
+Now you can direct connect VNC to any container built with this command!
+
+### I'd like to use SPICE instead of VNC
+
+Optionally, you can enable the SPICE protocol, which allows use of `remote-viewer` to access your OSX container rather than VNC.
+
+Note: `-disable-ticketing` will allow unauthenticated access to the VM. See the [spice manual](https://www.spice-space.org/spice-user-manual.html) for help setting up authenticated access ("Ticketing").
+
+```bash
+  docker run \
+    --device /dev/kvm \
+    -p 50922:10022 \
+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+    -e EXTRA="-monitor telnet::45454,server,nowait -nographic -serial null -spice disable-ticketing,port=3001" \
+    mycustomimage
+```
+
+Then simply do `remote-viewer spice://localhost:3001` and add `--spice-debug` for debugging.
+
+#### Creating images based on an already configured and set up container
+```bash
+# You can create an image of an already configured and setup container.
+# This allows you to effectively duplicate a system.
+# To do this, run the following commands
+
+# make note of your container id
+docker ps --all
+docker commit containerid newImageName
+
+# To run this image do the following
+docker run \
+    --device /dev/kvm \
+    --device /dev/snd \
+    -v /tmp/.X11-unix:/tmp/.X11-unix \
+    newImageName
+```

+    -e "DISPLAY=${DISPLAY:-:0.0}" \
+    sickcodes/docker-osx:auto
 
+# username is user

 Example:
-    ./generate-unique-machine-values.sh --count 1 --model='iMacPro1,1' --plists --bootdisks
-
-        The above example will generate a
-            - serial
-            - board serial
-            - uuid
-            - MAC address
-            - ROM value based on lowercase MAC address
-            - Boot disk qcow image.
-            - config.plist
-
-Notes:
-    - Default is 1 serial for 'iMacPro1,1' in the current working directory.
-    - Default output is CSV, whereas setting the TSV option will output as tab-separated.
-    - CSV is double quoted.
-    - If you do not set a CSV filename, the output will be sent to the output-dir.
-    - If you do not set an output-dir, the current directory will be the output directory.
-    - Sourcable environment variable shell files will be written to a folder, 'envs'.
-    - config.plist files will be written to a folder, 'plists'.
+    ./generate-unique-machine-values.sh --count 1 --plists --bootdisks --envs
+
+Defaults:
+    - One serial, for 'iMacPro1,1', in the current working directory
+    - CSV and TSV output
+    - plists in ./plists/ & bootdisks in ./bootdisks/ & envs in ./envs
+    - if you set --bootdisk name, --bootdisks is assumed
+    - if you set --custom-plist, --plists is assumed
+    - if you set --output-env, --envs is assumed
