Fuchsia Lab on MacOS

Setup

Set project and zone:

gcloud config set project my-test-project
gcloud compute project-info add-metadata --metadata google-compute-default-region=europe-west1,google-compute-default-zone=europe-west1-b
gcloud init

Create instance:

gcloud compute instances create fuchsia-lab \
  --machine-type=c3-highcpu-8 \
  --network-interface=network=default,network-tier=PREMIUM \
  --create-disk=boot=yes,image=projects/ubuntu-os-cloud/global/images/ubuntu-2304-lunar-amd64-v20230829,size=50 \
  --enable-nested-virtualization

Connect and enable KVM:

gcloud compute ssh fuchsia-lab
sudo usermod -a -G kvm ${USER}
exit

gcloud compute ssh fuchsia-lab
if [[ -w /dev/kvm ]] && grep '^flags' /proc/cpuinfo | grep -qE 'vmx|svm'; then echo 'KVM is working'; else echo 'KVM not working'; fi

Install tools:

sudo apt update
sudo apt upgrade -y
sudo apt install -y apt-transport-https gpg wget xrdp

# install VSCode tunnel
curl -L 'https://code.visualstudio.com/sha/download?build=stable&os=cli-alpine-x64' | sudo tar -xzC /usr/local/bin

# install Tailscale
curl -fsSL https://tailscale.com/install.sh | sh

# install Fuchsia SDK
git clone https://fuchsia.googlesource.com/sdk-samples/getting-started fuchsia-getting-started --recurse-submodules
cd fuchsia-getting-started
scripts/bootstrap.sh
tools/bazel build @fuchsia_sdk//:fuchsia_toolchain_sdk
tools/ffx sdk version
tools/ffx product-bundle get workstation_eng.qemu-x64 --force-repo --repository workbench-packages

Run emulator

Start Fuchsia emulator and repository server:

tools/ffx emu start workstation_eng.qemu-x64 --headless
tools/ffx target default set fuchsia-emulator
tools/ffx target show

tools/ffx repository server start
tools/ffx target repository register -r workbench-packages --alias fuchsia.com --alias chromium.org

Inspect running Fuchsia instance:

tools/ffx component list

Connect via VSCode

Enable VS Code tunnel:

sudo loginctl enable-linger $USER
code tunnel service install

Use "Remote Tunnels: Connect to Tunnel..." action locally.

Graphics

Install Tailscale on your machine and also enable the Tailscale tunnel on the VM:

sudo tailscale up

Set user password:

sudo passwd $USER

Use Microsoft Remote Desktop to connect. Simply use "fuchsia-lab" as the "PC name", since Tailscale should take care of resolving the IP address. There will be no window manager, but that's okay.

Start emulator in your SSH session (not the remote desktop):

export DISPLAY=:10.0
tools/ffx emu start workstation_eng.qemu-x64 --gpu swiftshader_indirect

You should now see the graphical interface of the emulator and you should even be able to run Chromium in Fuchsia.
