ESX Server 1.0 - Trip down memory lane

by // 9 Comments

I recently had a bit of VMware Nostalgia and for the past several weeks, I have been working on a personal skunk works project in trying to locate all major ESX and ESXi releases over the past 22 years including ESX Server 1.0 which was released by VMware back in 2001!

To my surprise, finding a digital copy of ESX pre-2.0 (1.0 & 1.5) was much harder than I had expected. Back in those early days, software was not commonly distributed over the internet like it is today, instead it was sent to vendors to create physical CD/DVD discs, which was then shipped to customers and partners. I had also reached out to many tenured folks at VMware who were still around from the early days, but each response lead to another set of folks and it typically either went in a circle or to a dead end. This was turning into an archeological hunt.

I decided to give it one more shot and I pinged John Arrasjid aka VCDX #1 and after a bit of searching, John actually found a pristine copy of ESX Server 1.0, still sealed in the box! Given how difficult it was to locate a 1.0 copy of ESX, we thought it was worth opening up and to preserve this VMware history by creating a digital ISO image, so that I could then share the experience of installing ESX 1.0 with the broader VMware community.

vSphere Datasets - New Virtual Machine Metadata Service in vSphere 8

by // 1 Comment

Since the early days of Virtual Center and ESX, the only method for creating and sharing arbitrary metadata between the vSphere Management layer and the guest operating system was to use either guest variables (guestinfo) or the OVF runtime environment.

While both of these capabilities have enabled a ton of interesting use cases and have even inspired creative solutions such as this, this, this, this and this to just name a few, it certainly has its challenges and nuances from an end user experience perspective.

For example, the persistency or the non-persistency of guest variables solely depended on when it was applied to a Virtual Machine and the power state it was in, which can be very frustrating to discover for the first time and the inconsistent behavior for end users. The lack of security and access control in both guest variables and the OVF runtime environment also means the metadata could easily be overwritten or removed by users in either the vSphere Management layer or guest operating system, making this challenging to scale for larger organizations.

This is why I am excited for vSphere 8 and the new vSphere Dataset feature!

Closer look at vSphere Permissions for vSphere with Tanzu 

by // 3 Comments

Questions regarding vSphere Permissions for vSphere with Tanzu has been frequently brought up more lately and the majority of questions that I have seen, has primarily focused on the behavior of the vSphere UI Inventory. After taking a closer look and experimenting with a few permutations within my lab, I realized that most folks were simply focusing on what they were most familiar with, which is using the vSphere UI to interact with vSphere.

Although vSphere with Tanzu is tightly integrated with vSphere and the vSphere UI is certainly a primary interface, it is certainly not the only interface nor is it always the interface for end users like a developer. Depending on the needs of your end users and how your organization wishes to grant access to a vSphere Namespace, there are actually a few options that are available to you. In fact, users can interact with vSphere with Tanzu without ever logging into the vSphere UI and that is completely valid and may even be desirable for some organizations.

Note: The custom kubectl plugin for vSphere (kubectl-vsphere) which is needed to interact with vSphere with Tanzu can be downloaded by simply opening a browser (or use wget) to following URL: https://[SUPERVISOR-CLUSTER-IP]/wcp/plugin/[OS]-amd64/vsphere-plugin.zip, where OS is darwin, linux or windows (e.g. https://172.17.33.33/wcp/plugin/darwin-amd64/vsphere-plugin.zip)

Below are the results of my testing using the various vSphere Roles and Groups including the various behavior across the different consumption interfaces including the vSphere UI. To help better illustrate the results, I am also using some example personas, these are purely used as an example and may differ based on your organizational needs.

Persona: VI/Cloud Admin

In this scenario, the user is a vSphere Administrator and has the following memberships:

  • vSphere Role: Administrator
  • vSphere SSO Group: Administrators
  • vSphere Namespace: SSO User and/or Active Directory User

The user will be able to view and manage all vSphere infrastructure including the vSphere Namespaces and the respective workloads including TKG Workload Clusters and/or VMs via the VM Service.

Here is a summary of this users access:
