Build
USER=mygithubuser
PASSWORD=mysecurepasswordthatIwillneverusebecauseIuseMostlySSHkeys
OUTPUT=workstation.qcow2
d2vm build -o $OUTPUT --force --build-arg USER=$USER --build-arg PASSWORD=$PASSWORD --build-arg SSH_KEY=https://github.com/$USER.keys .
Run it using libvirt's virt-install:
virt-install --name workstation --disk $OUTPUT --import --memory 4096 --vcpus 4 --nographics --cpu host --channel unix,target.type=virtio,target.name='org.qemu.guest_agent.0'
... you should be automatically logged in with a oh-my-zsh shell
From an other terminal you should be able to find the VM ip address using:
virsh domifaddr --domain workstation
And connect using ssh...
I hope you will find it useful and that you will have fun...
