# Requirements: KVM on the host
|
|
Need to turn on hardware virtualization in your BIOS, very easy to do.
|
|
|
|
Then have QEMU on the host if you haven't already
|
|
|
|
```bash
|
|
# ARCH
|
|
sudo pacman -S qemu libvirt dnsmasq virt-manager bridge-utils flex bison iptables-nft edk2-ovmf
|
|
|
|
# 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
|
|
|
|
# then run
|
|
sudo systemctl enable libvirtd.service
|
|
sudo systemctl enable virtlogd.service
|
|
|
|
sudo modprobe kvm
|
|
|
|
# reboot
|
|
```
|
|
|
|
# Start the same container later (persistent disk)
|
|
|
|
This is for when you want to run the SAME container again later.
|
|
|
|
If you don't run this you will have a new image every time.
|
|
|
|
```bash
|
|
# look at your recent containers and copy the CONTAINER ID
|
|
docker ps --all
|
|
|
|
# docker start the container ID
|
|
docker start abc123xyz567
|
|
|
|
# if you have many containers, you can try automate it with filters like this
|
|
# docker ps --all --filter "ancestor=sickcodes/docker-osx"
|
|
# for locally tagged/built containers
|
|
# docker ps --all --filter "ancestor=docker-osx"
|
|
|
|
```
|
|
|
|
# Additional Boot Instructions
|
|
|
|
- Boot the macOS Base System
|
|
|
|
- Click `Disk Utility`
|
|
|
|
- Erase the BIGGEST disk (around 200gb default), DO NOT MODIFY THE SMALLER DISKS.
|
|
-- if you can't click `erase`, you may need to reduce the disk size by 1kb
|
|
|
|
- (optional) Create a partition using the unused space to house the OS and your files if you want to limit the capacity. (For Xcode 12 partition at least 60gb.)
|
|
|
|
- Click `Reinstall macOS`
|
|
|
|
|
|
## Creating images:
|
|
```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
|
|
```

# How to Enable Network Forwarding
|
|
|
|
Allow ipv4 forwarding for bridged networking connections:
|
|
|
|
This is not required for LOCAL installations and may cause containers behind [VPN's to leak host IP](https://sick.codes/cve-2020-15590/).
|
|
|
|
If you are connecting to a REMOTE Docker-OSX, e.g. a "Mac Mini" in a datacenter, then this may boost networking:
|
|
|
|
```bash
|
|
# enable for current session
|
|
sudo sysctl -w net.ipv4.ip_forward=1
|
|
|
|
# OR
|
|
# sudo tee /proc/sys/net/ipv4/ip_forward <<< 1
|
|
|
|
# enable permanently
|
|
sudo touch /etc/sysctl.conf
|
|
sudo tee -a /etc/sysctl.conf <<EOF
|
|
net.ipv4.ip_forward = 1
|
|
EOF
|
|
|
|
# OR edit manually
|
|
nano /etc/sysctl.conf || vi /etc/sysctl.conf || vim /etc/sysctl.conf
|
|
|
|
# now reboot
|
|
```
|

# How to install Docker if you don't have Docker already
|
|
|
|
```bash
|
|
### Arch
|
|
sudo pacman -S docker
|
|
sudo groupadd docker
|
|
sudo usermod -aG docker "${USER}"
|
|
|
|
### Ubuntu
|
|
|
|
sudo apt remove docker docker-engine docker.io containerd runc -y
|
|
sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common -y
|
|
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
|
|
apt-key fingerprint 0EBFCD88
|
|
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
|
|
sudo apt update -y
|
|
sudo apt install docker-ce docker-ce-cli containerd.io -y
|
|
sudo groupadd docker
|
|
sudo usermod -aG docker "${USER}"
|
|
|
|
|
|
```
|
|
|
|
### Fedora: if you have no internet connectivity from the VM, and you are using bridge networking:
|
|
|
|
```bash
|
|
# Set the docker0 bridge to the trusted zone
|
|
sudo firewall-cmd --permanent --zone=trusted --add-interface=docker0
|
|
sudo firewall-cmd --reload
|
|
```
|
|
|
|
# Backup the disk (Where's my disk?)
|
|
|
|
You can use `docker cp`
|
|
|
|
```bash
|
|
# docker copy your image OUT of your container (warning, double disk space)
|
|
docker cp oldcontainerid:/home/arch/OSX-KVM/mac_hdd_ng.img .
|
|
```
|
|
|
|
Or if you lost your container, find it with this:
|
|
|
|
```bash
|
|
# fast way, find 10 gigabyte OSX disks hiding in your docker container storage
|
|
sudo find /var/lib/docker -size +10G | grep mac_hdd_ng.img
|
|
|
|
# you can move (mv) it somewhere, using cp can take loads of disk space
|
|
sudo mv somedir/mac_hdd_ng.img .
|
|
|
|
```
|
|
|
|
# Use an Old Docker-OSX Disk in a Fresh Container (Replication)
|
|
|
|
You do not have to reinstall everything, you can simply:
|
|
|
|
- start a new container
|
|
|
|
- overwrite the .img in the new container with your big old one
|
|
|
|
```bash
|
|
|
|
# start a new docker-osx container
|
|
# you can start with ssh, without, or vnc, because they are all interchangable.
|
|
|
|
# get the NEW container id
|
|
docker ps
|
|
|
|
# docker cp your OLD disk into the NEW container
|
|
docker cp ./mac_hdd_ng.img newcontainerid:/home/arch/OSX-KVM/mac_hdd_ng.img
|
|
|
|
# kill the NEW container
|
|
docker kill newcontainerid
|
|
|
|
# start the NEW container and it just works
|
|
docker start newcontainerid
|
|
|
|
```
|
|
|
|
# DESTROY: Wipe old images to free disk space
|
|
|
|
This is useful for getting disk space back.
|
|
|
|
It will delete ALL your old (and new) docker containers.
|
|
|
|
```bash
|
|
# WARNING deletes all old images, but saves disk space if you make too many containers
|
|
# The following command will make your containers RIP
|
|
docker system prune --all
|
|
docker image prune --all
|
|
```
|
|
|
|
# INSTANT OSX-KVM in a BOX!
|
|
This Dockerfile automates the installation of OSX-KVM inside a docker container.
|
|
|
|
It will build a Catalina Disk with up to 200GB of space.
|
|
|
|
You can change the size and version using build arguments (see below).
|
|
|
|
This file builds on top of the work done by Dhiru Kholia and many others on the OSX-KVM project.
|
|
|
|
# CI/CD Related Improvements
|
|
## How to reduce the size of the image
|
|
* Start up the container as usual, and remove unnecessary files. A useful way
|
|
to do this is to use `du -sh *` starting from the `/` directory, and find
|
|
large directories where files can be removed. E.g. unnecessary cached files,
|
|
Xcode platforms, etc.
|
|
* Once you are satisfied with the amount of free space, enable trim with `sudo trimforce enable`, and reboot.
|
|
* Zero out the empty space on the disk with `dd if=/dev/zero of=./empty && rm -f empty`
|
|
* 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.
|
|
* Run `qemu-img convert -O qcow2 mac_hdd_ng.img deduped.img` and check for errors again
|
|
* OPTIONAL: Run `qemu-img -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%.
|
|
* Check for errors again, and build a fresh docker image. E.g. with this Dockerfile
|
|
|
|
```
|
|
FROM sickcodes/docker-osx
|
|
USER arch
|
|
COPY --chown=arch ./deduped.img /home/arch/OSX-KVM/mac_hdd_ng.img
|
|
```
|
|
|
|
## How to run in headless mode
|
|
First make sure [autoboot is enabled](#autoboot-into-osx-after-youve-installed-everything)
|
|
|
|
Next, you will want to set up SSH to be automatically started.
|
|
|
|
```bash
|
|
sudo systemsetup -setremotelogin on
|
|
```
|
|
|
|
Make sure to commit the new docker image and save it, or rebuild as described in the [section on reducing disk space](#how-to-reduce-the-size-of-the-image).
|
|
|
|
Then run it with these arguments.
|
|
|
|
```bash
|
|
# Run with the -nographic flag, and enable a telnet interface
|
|
docker run \
|
|
--device /dev/kvm \
|
|
-p 50922:10022 \
|
|
-e "DISPLAY=${DISPLAY:-:0.0}" \
|
|
-e EXTRA="-monitor telnet::45454,server,nowait -nographic -serial null" \
|
|
mycustomimage
|
|
```
|
|
|
|
Optionally, you can enable the SPICE protocol, which allows you to use `remote-viewer` to access it rather than VNC.
|
|
|
|
Note: `-disable-ticketing` will allow unauthenticated access to the VM. See the [spice manual](https://www.spice-space.org/spice-user-manual.html) for help setting up authenticated access ("Ticketing").
|
|
|
|
```bash
|
|
docker run \
|
|
--device /dev/kvm \
|
|
-p 50922:10022 \
|
|
-e "DISPLAY=${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.
|
|
|
|
|
|
# Custom Build or Local Development
|
|
|
|
If you are building Docker-OSX locally, you will want to use Arch Linux mirrors.
|
|
|
|
Mirror locations can be found here (use 2 letter country codes): https://archlinux.org/mirrorlist/all/
|
|
|
|
```bash
|
|
docker build -t docker-osx:latest \
|
|
--build-arg RANKMIRRORS=yes \
|
|
--build-arg MIRROR_COUNTRY=US \
|
|
--build-arg MIRROR_COUNT=10 \
|
|
--build-arg VERSION=10.15.6 \
|
|
--build-arg SIZE=200G .
|
|
```
|
|
|
|
# Custom QEMU Arguments (passthrough devices)
|
|
|
|
Pass any devices/directories to the Docker container & the QEMU arguments using the handy `-e EXTRA=` runtime options.
|
|
|
|
```bash
|
|
docker run \
|
|
-e RAM=4 \
|
|
-e SMP=4 \
|
|
-e CORES=4 \
|
|
-e EXTRA='-usb -device usb-host,hostbus=1,hostaddr=8' \
|
|
-e INTERNAL_SSH_PORT=23 \
|
|
--device /dev/kvm \
|
|
--device /dev/snd \
|
|
-v /tmp/.X11-unix:/tmp/.X11-unix \
|
|
docker-osx:latest
|
|
|
|
```
|
|
|
|
# Allow USB passthrough
|
|
|
|
The simplest way to do this is the following:
|
|
|
|
First of all, in order to do this, QEMU must be started as root. It is also potentially possible to do this by changing the permissions of the device in the container.
|
|
See [here](https://www.linuxquestions.org/questions/slackware-14/qemu-usb-permissions-744557/#post3628691).
|
|
|
|
For example, create a new Dockerfile with the following
|
|
|
|
```bash
|
|
FROM sickcodes/docker-osx
|
|
USER arch
|
|
RUN sed -i -e s/exec\ qemu/exec\ sudo\ qemu/ ./Launch.sh
|
|
COPY --chown=arch ./new_image.img /home/arch/OSX-KVM/mac_hdd_ng.img
|
|
```
|
|
|
|
Where `new_image.img` is the qcow2 image you extracted. Then rebuild with `docker build .`
|
|
|
|
Find out the bus and port numbers of your USB device which you want to pass through to the VM.
|
|
|
|
```bash
|
|
lsusb -t
|
|
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
|
|
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M
|
|
|__ Port 2: Dev 5, If 0, Class=Human Interface Device, Driver=usbhid, 12M
|
|
|__ Port 2: Dev 5, If 1, Class=Chip/SmartCard, Driver=, 12M
|
|
|__ Port 3: Dev 2, If 0, Class=Wireless, Driver=, 12M
|
|
|__ Port 3: Dev 2, If 1, Class=Wireless, Driver=, 12M
|
|
|__ Port 5: Dev 3, If 0, Class=Video, Driver=uvcvideo, 480M
|
|
|__ Port 5: Dev 3, If 1, Class=Video, Driver=uvcvideo, 480M
|
|
```
|
|
|
|
In this example, we want to pass through a smartcard device. The device we want is on bus 1 and port 2.
|
|

There may also be differences if your device is usb 2.0 (ehci) vs usb 3.0 (xhci).
|
|
See [here](https://unix.stackexchange.com/a/452946/101044) for more details.
|
|
|
|
|
|
```bash
|
|
# hostbus and hostport correspond to the numbers from lsusb
|
|
# runs in privileged mode to enable access to the usb devices.
|
|
docker run \
|
|
--privileged \
|
|
--device /dev/kvm \
|
|
-e RAM=4 \
|
|
-p 50922:10022 \
|
|
-e "DISPLAY=${DISPLAY:-:0.0}" \
|
|
-e EXTRA="-device virtio-serial-pci -device usb-host,hostbus=1,hostport=2" \
|
|
mycustomimage
|
|
```
|
|
|
|
You should see the device show up when you do `system_profiler SPUSBDataType` in the MacOS shell.
|
|
|
|
Important Note: this will cause the host system to lose access to the USB device while the VM is running!

## What is `${DISPLAY:-:0.0}`?
|
|
|
|
`$DISPLAY` is the shell variable that refers to your X11 display server.
|
|
|
|
`${DISPLAY}` is the same, but allows you to join variables like this:
|
|
|
|
- e.g. `${DISPLAY}_${DISPLAY}` would print `:0.0_:0.0`
|
|
- e.g. `$DISPLAY_$DISPLAY` would print `:0.0`
|
|
|
|
...because `$DISPLAY_` is not `$DISPLAY`
|
|
|
|
`${variable:-fallback}` allows you to set a "fallback" variable to be substituted if `$variable` is not set.
|
|
|
|
You can also use `${variable:=fallback}` to set that variable (in your current terminal).
|
|
|
|
In Docker-OSX, we assume, `:0.0` is your default `$DISPLAY` variable.
|
|
|
|
You can see what yours is
|
|
```bash
|
|
echo $DISPLAY
|
|
```
|
|
Hence, `${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`?
|
|
|
|
`-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.
|
|
|
|
`/tmp/.X11-unix`
|
|
|
|
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)
