How to setup a virtual machine or virtual appliance in an IBM Cloud virtual private cloud (vpc) environment on a virtual server instance (vsi)? (nested Hypervisor)

As fas as I notice from the official IBM Cloud documentation “VPC responsibilities“, there is no official support for a nested Hypervisor listed in the official IBM Cloud documentation (Date 14.09.2021). IBM provides in the official IBM Cloud documentation: How to manually enable nested virtualization on a virtual server instance?, but you can do this on your own risk, as far as I understand for now. For me the nested Hypervisor worked for several times, but it’s not official supported.


This is a cheat sheet about, how to setup a virtual machine or virtual appliance in an IBM Cloud virtual private cloud (vpc) on a virtual server instance (vsi) with Red Hat Enterprise Linux 8 minimal install (RHEL8) as host operating system and a Ubuntu Linux operating system for the virtual machine or virtual appliance. I reuse different blog posts and references to documentations on IBM Cloud or Red Hat and I use the information from an exchange with Stefan Trimborn and Marc Haecker. (Thanks and greetings Stefan and Marc ;-))

This blog post covers the setup until the network configuration for the virtual machine (vm) or virtual appliance (va) to access for example a web application from the internet, which runs in the vm or va.

The image below shows a simplified diagram of the setup on IBM Cloud:

How to create a single virtual server instance (VSI) in a virtual private cloud (VPC) infrastructure on IBM Cloud

This is a “simple” cheat sheet, how to create a single virtual server instance (VSI) in the virtual private cloud (VPC) infrastructure on IBM Cloud.

The blog post has four major sections:

  1. Example architecture
  2. Setup of a VPC network
  3. Setup and configure the virtual server instance inside the VPC network
  4. Access the virtual server instance from a local machine

For more information, please visit the VPC IBM Cloud documentation.

Keep in mind: The objective is not to show all awesome additional capabilities the virtual private cloud on IBM Cloud has. The objective is just to provide a simple cheat sheet to create one simple virtual server instance.
