VMware Flings Update

by // 25 Comments

This has been a difficult week for all VMware employees due to the pending acquisition of VMware by Broadcom. Many VMware employees are still waiting to hear back from Broadcom about their employment status either before and/or after the planned acquisition close date. I wanted to provide this context before sharing a quick update regarding the VMware Flings program.

On Tuesday October 24th, VMware Fling authors was made aware that the VMware Flings site (flings.vmware.com) would be taken down and website would simply be redirected to developer.vmware.com/samples starting on Thursday October 26th.

The VMware Flings program was operated and run by VMware's Office of the CTO (OCTO) and while I do not have specifics on why it needed to go down, I tried my best to share out the news as broadly and as quickly as I could so that folks could at least grab what they needed. While the original notice mentioned the site would function up until 10/26 at 5pm PST, it looks VMware IT had already made the DNS changes and the redirect has already been propagated.

As of right now, I do not know the future of the VMware Flings program, but I did want to share a few updates since the site and its downloads are no longer available.

Troubleshooting ESXi Shutting down firmware services and UEFI Runtime Services (RTS) error message

by // 1 Comment

Several months back, I was helping a customer debug an issue where I needed to install the GA release of ESXi 6.7! Yikes, it certainly has been a minute since I have installed anything older than 7.x but I figured it should still work fine with recent hardware like an Intel NUC systems, right?

After the ESXi installer started to boot up, it eventually halted with the following message:

Shutting down firmware services...

Using 'simple offset' UEFI RTS mapping policy


I decided to give it one more go by using a more recent release of ESXi 6.7 Update 3 and to my surprise, not only did ESXi installed perfectly fine but I did not run into the error message shown abvove!

I then realized that perhaps this has something to do with the ESXi bootloader, like any piece of software, there are fixes and enhancements with newer releases. I also recall a conversation with one of our Engineers that the ESXi bootloader is also designed to be backwards compatible, so that gave me an idea to try replacing the default ESXi 6.7 GA bootloader files with the ones found in ESXi 6.7 Update 3 and now I was able to install ESXi 6.7 GA release!

However, my success did not last very long as I ran into a slightly different message after the initial reboot:

Shutting down firmware services…

UEFI runtime services support is disabled

How to setup Harbor registry on Synology

by // 6 Comments

With my recent exploration of GenAI and using a private ChatGPT solution with my own blog posts, I quickly realized in the space of AI/ML, the required software dependencies can take up a significant amount of storage, especially for a kubernetes/container-based deployment.

To give you an example, to deploy the private ChatGPT (h2ogpt) application using kubernetes, just the container image itself is a whopping 40GB+! 😲

Unfourntately, this is not a one off scenario but a common theme when working in the AI/ML space that the size of the packages and drivers are extremely large even when using containers. I figure I should probably setup my own container registry instead of pulling directly from the Internet given the size of these images.

I already have a local Harbor instance running in a VM but with my Synology, I have been using it centralize a number of functions and that would be the ideal place to actually run Harbor. While you can run individual containers on the Synology as I have demonstrated HERE with GitLab, the Harbor installation processes relies on Docker Compose, which Synology does not natively support using the Synology DiskStation Manager (DSM) interface.

With a little bit of tinkering and trial/error, I was able to finally get Harbor running on my Synology and centralize all my storage needs including having my own container registry.
