vm

Linux VMs on ARM64

Getting vm

mkdir vm && curl -L https://github.com/pluvial/vm/archive/main.tar.gz | tar xzf - --strip-components=1
mkdir vm && wget https://github.com/pluvial/vm/archive/main.tar.gz -O - | tar xzf - --strip-components=1
git clone --depth=1 https://github.com/pluvial/vm

Building vm binary

./build.sh
# or
xcodebuild -arch arm64

Run Ubuntu VM

ubuntu/run.sh

Mount host shared directories:

sudo mkdir /mnt/host
sudo mount -t virtiofs host /mnt/host
# or add to /etc/fstab :
# host /mnt/host virtiofs defaults 0 0

Setup Alpine VM

In Ubuntu VM:

cd /mnt/host/cwd/alpine
sudo ./build.sh

Creates /mnt/host/cwd/vm-build

In host:

mv vm-build/* alpine
alpine/setup.sh

Run Alpine VM

alpine/run.sh

SSH into VM

In VM:

apk add dropbear && reboot

In host:

alpine/ssh.sh

Setup Podman

In VM:

./setup-vdb.sh
./setup-podman.sh

Test with:

podman run --rm -it alpine

Build Linux in Podman

./build.sh

Creates ~/build/vmlinuz, can be copied to host with:

cp build/vmlinuz /mnt/host/cwd/

Cleaning

Clean disk images:

./clean.sh

Clean disk images, downloads, and build artifacts

./clean.sh --all
