How to import the GNS3 SONiC Datacenter image to Proxmox?

[stordis-toc]

Introduction

Welcome to the GNS3 SONiC on Proxmox deployment guide!

This article explains how to import the GNS3 SONiC Datacenter image into a Proxmox environment. By following these steps, you can run SONiC network simulations directly on your hypervisor without the need for additional physical hardware.

Hardware Requirements

• Virtual Environment: VMware ESXi 6, Proxmox 8, or newer versions
• CPU: 24 virtual cores (vCPU)
• Memory: min. 50 GB RAM required
• Storage: min. 100 GB disk space (final requirement depends on your specific storage configuration)

Import the Virtual Machine into Proxmox

STEP 1: Launch Proxmox page on your web browser.

STEP 2: Select "Create VM"

STEP 3: Name Virtual Machine:

STEP 4: In the OS section choose Do not use any media:

STEP 5: Leave default settings in the System section:

STEP 6: Remove the default virtual disk:

STEP 7: Configure CPU:

STEP 8: Set the memory as needed:

STEP 9: Leave the network settings default:

STEP 10: Turn off “Start after creation” in the confirmation step:

STEP 11: Upload and Import the Disk Image

• Use an SCP tool or command to copy your .vmdk to the Proxmox host.

STEP 12: Convert and Import the Disk

• Access the Proxmox shell:

   

• Run import command (for both disk images):

  qm importdisk <VMID> <name.vmdk> <storage> --format <format>

  Example:

  qm importdisk 114 DataCenterinGNS3-1.vmdk local --format qcow2

  

  Note

  This process can take up to 4 hours, depending on your system specifications and configuration.

• Run the following to rescan the disks:

  qm rescan

• Attach the new disks via the Hardware tab and start the VM

   

• In the Options tab, set the correct boot disk as first and make sure that it is enabled.

  

STEP 13: Finalize Configuration and Boot the VM

• Make sure that KVM hardware virtualization is enabled

  

• Start the VM.

  

• Once booted, note the displayed Web UI IP address for GNS3.

  

STEP 14: Access GNS3 and Import SONiC

• Open your browser and navigate to the displayed IP address (Web UI).
