📀 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.

Which NXOS version are you using and what kind of processor are they running on? In the past I had a lot of crashes with an older virtual CPU. It got better when I upgraded towards a bare metal host with an current gen one.

To check virtualization, do the following: Run this: kvm-ok Then this: grep -cw vmx /proc/cpuinfo And check the results. If CPU returns 0 or KVM is not supported, then enable virtualization on your VM.

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!
