How to install PNETLab on GCP
1. Open cloud console in GCP once you are in the CLI, run below command depending on the PNETLab version you want to install.
- PNETLab version 5 (Ubuntu 18.04):
gcloud compute images create nested-ubuntu-bionic --source-image-family=ubuntu-1804-lts --source-image-project=ubuntu-os-cloud --licenses https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx
- PNETLab version 6 (Ubuntu 20.04):
gcloud compute images create nested-ubuntu-focal --source-image-family=ubuntu-2004-lts --source-image-project=ubuntu-os-cloud --licenses https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx
2. Create a VM instance with the specs you want.
Recommendations:
CPU: Intel CPUs Skylake or Cascade
Disk: SSD for better performance
- For the boot disk, select the nested image that you created in step 1
- Allow HTTP and HTTPS traffic
- "Deploy a container image” must be UNCHECKED
- After the VM is created, ssh to it and switch to the root user:
sudo -i
3. Run the installation script for the corresponding PNETLab version: check the installation instructions for each version by issuing the command /notes in PNETLab's group.
Once installation is completed reboot the VM with this command:
reboot
Wait for few seconds while the VM reboots and ssh to it again.
When the setup wizard screen appears, press ctrl + c and type the below command to switch to the root user:
sudo -i
You'll get setup wizard again. When it asks you to enter your new root password, enter it twice, give a hostname of choice, domain name of choice, and select DHCP (don't use static ip ), and leave NTP blank.
And that's it. Enjoy PNETLab!

📀 Installation instructions - PNetLab v6 BETA release
⚠️ Read the full instructions and important notes before starting the process. After you finish reading them, follow the process step by step.
Step 1
Download the Ubuntu Server 20.04 ISO and install the OS on a VM or bare metal.
Step 2
Run the installation script as root (copy-paste the full thing):
curl -sL https://labhub.eu.org/api/raw/?path=/UNETLAB%20I/upgrades_pnetlab/Focal/install_pnetlab_v6.sh | bash
After the installation script finishes running, reboot the server.
ℹ️ Important notes
- Make sure to enable Virtualization on your system BIOS and make sure your hardware supports nested virtualization.
Check if you meet the requirements by running:
grep -cw vmx /proc/cpuinfo
Check if KVM was installed correctly after the installation script finishes running:
kvm-ok
- When installed on GCP, skip the setup wizard by pressing CTRL + C after the first reboot and if you're tired of having to do that at every login, ask how to disable in this chat.
⚠️ Remember this version is still on beta so you might encounter bugs and unfinished features.
