bmpotter / qemu-cross-testdev

QEMU/Docker automation for test/dev of emulated systems (arm, aarch64, ppc64, x86, x86_64)

Horizon cross testdev

Prereq

Ubuntu 18.04 (or 16.04) x86_64 with 4 virtual (2 physical) cores and 4 GB RAM.

echo "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/ubuntu xenial edge" >/etc/apt/sources.list.d/docker.list
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -qq - >/dev/null
apt-get update
apt-get install -y qemu-kvm docker-ce make git

Run

As root:

git clone https://github.com/open-horizon/qemu-cross-testdev
cd qemu-cross-testdev

(Optional) For testing with Ubuntu 16.04 images:

git checkout u16

32-bit ARM:

time make testdev ARCH=arm

64-bit ARM:

time make testdev ARCH=aarch64

PPC64:

time make testdev ARCH=ppc64le

x86_64:

time make testdev ARCH=x86_64

The first run will take sometime (~22 min) to download and build the QEMU images. Any time after that it should be pretty quick.

Check if ready (after make testdev returns)

docker logs testdev, look for testdev ready to go!!! message. (~3 min boot time)

Get a shell (after ready)

NOTE: if you copy id_rsa to your local workstation, this command will work from your local workstation, or CI system, etc...

docker cp testdev:/root/.ssh/id_rsa id_rsa
ssh -i id_rsa -o StrictHostKeyChecking=no -p 2222 root@your_machine_ip_address # not localhost

[Clean] shutdown

docker cp testdev:/root/.ssh/id_rsa id_rsa
ssh -i id_rsa -o StrictHostKeyChecking=no -p 2222 root@your_machine_ip_address reboot

Check with docker ps -a that the container has stopped, then cleanup with the hard shutdown below.

[Hard] shutdown

make stopdev
