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:

# ARCHsudo pacman -S qemu libvirt dnsmasq virt-manager bridge-utils flex bison ebtables edk2-ovmf# UBUNTU DEBIANsudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager# CENTOS RHEL FEDORAsudo yum install libvirt qemu-kvm -y# then runsudo systemctl enable libvirtd.servicesudo systemctl enable virtlogd.servicesudo modprobe kvm# reboot

Start the same container later (persistent disk)

# look at itdocker ps --all --filter "ancestor=docker-osx"# boot my old onedocker start $(docker ps -q --all --filter "ancestor=docker-osx")

Additional Boot Instructions

# Boot the macOS Base System# Click Disk Utility# Erase the biggest disk# Partition that disk and subtract 1GB and press Apply# Click Reinstall macOS

Docker install

If you don't have Docker already

### Arch (pacman version isn't right at time of writing)wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.5.tgztar -xzvf docker-*.tgzsudo cp docker/* /usr/bin/sudo dockerd &sudo groupadd dockersudo usermod -aG docker $USER# run docker latersudo nohup dockerd &### Ubuntuapt-get remove docker docker-engine docker.io containerd runc -yapt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common -ycurl -fsSL https://download.docker.com/linux/ubuntu/gpg |  apt-key add -apt-key fingerprint 0EBFCD88add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"apt-get update -yapt-get install docker-ce docker-ce-cli containerd.io -y

Backup the disk

your image will be stored in:

/var/lib/docker/overlay2/...../arch/OSX-KVM/home/arch/OSX-KVM/mac_hdd_ng.img

# find your container's root folderdocker inspect $(docker ps -q --all --filter "ancestor=docker-osx") | grep UpperDir# In the folder from the above command, your image is inside ./home/arch/OSX-KVM/mac_hdd_ng.img# then sudo cp it somewhere. Don't do it while the container is running tho, it bugs out.

Wipe old images

# WARNING deletes all old images, but saves disk space if you make too many containersdocker system prune --alldocker 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 32GB Mojave Disk.

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.

Custom Build

docker build -t docker-osx:latest \--build-arg VERSION=10.14.6 \--build-arg SIZE=200Gdocker run --privileged -v /tmp/.X11-unix:/tmp/.X11-unix docker-osx:latest

Todo:

# persistent disk with least amount of pre-build errands.
