*00-netconf.yaml*
|

```yaml
|

network:

|
ethernets:
|
|
eth0:
|
|
dhcp4: true
|
|
nameservers:
|
|
addresses:
|
|
- 8.8.8.8
|
|
- 8.8.4.4
|
|
|
|
```
|
|
|
|
**Build**
|
|
|
|
```bash
|
|
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*:
|
|
|
|
```bash
|
|
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:
|
|
```bash
|
|
virsh domifaddr --domain workstation
|
|
```
|
|
|
|
And connect using ssh...
