Even more on ESX 3i: commentary, and running in a VM
We all know you can run ESX Server in a VM (you know that, right?). Thomas Bishop already has the ESX Server 3i beta working in Fusion, and Eric Sloof has it going in Server. Thomas also has an interactive shell running at boot. See this forum thread for all the acrobatics, where pbraren and others are contributing. It's quite a fascinating mix of technical step-by-step investigation and rumination on the significance of 3i and where the hypervisor is going.
Also, the ESX Server 3i session presentation from VMworld is available from us. (hat tip to Mike Laverick, who knew about it before I did. I can tell you that the rest of the VMworld presentation pdfs should be available on the new VMworld.com very soon, and most of the streaming sessions are already available. You must have a conference login to view them for now.)
A bit of commentary as well. J Hicks says in the comments on the last 3i post:
Don't get me wrong, 3i is a great next step. Avoiding the RH based service console and the associated patching is fantastic. However, what really matters is not just the hypervisor itself, but the way its managed. And 3i = 3, same code, different delivery, same management (VC). ...
Its very interesting to see the corner we're turning here. Initially VMware was touting "repurpose the hardware you have" - but now the hardware vendors are delivering boxes that may only make sense for virtulized hosts. (not that that's a bad thing, just something to ponder).
And the always-insightful Massimo Re Ferre has an essay on what he sees as the significance of ESX Server 3i -- in short, it's a step forward in the natural evolution of the product, but for now it's still the ESX Server we know and love.
Link: What (really) VMware ESX 3i is (to me)
So what does this buy you as an end user? Yes me too I think... not so much. Sure it has a much smaller attack surface for viruses and security vulnerability that means less updates so less troubles for system administrators. Also it finally allows to get rid of these legacy 2 hard disk drives in rack servers and more importantly blades transforming them in true stateless devices ... as they should be. Yet not really something you would go through the streets of San Francisco screaming "oh boy what they managed to invent!?!"
In conclusion, I didn't certainly want to diminish the value that 3i is bringing into the industry. I am very excited about it because I think it's a step towards the right direction. However I think it is important to clarify some of the rumors and misinformation that have been circulating and that I am sure will circulate even after the details are disclosed.
Massimo is worried that an excited sales force will be overhyping 3i as the ultimate hypervisor. I saw a lot of science fictional speculation before the announcement, but the reporting post-announcement has been pretty sober -- pointing out the clear advantages in deployment and patch reduction and architectural simplicity, but not proclaiming that we've reached the promised land. So don't worry, Massimo, you can be excited about 3i without overhyping it. You know VMware is not a company given to too much hype -- but as kimono says in the discussion thread, 3i is "a seriously hot piece of kit."

Hi John.
Sure you are right that VMware (meaning "the Console") is not going to cheat about 3i and VMware is not officially going to say this is anything different than what it actually is. And what it is, let me stress again, it is very intresting.
However yesterday I met a VMware BP and all of a sudden he said "oh, have you heard about this new hypervisor on the motherboard VMware has just announced? Since it runs at a it will be able to support more vm's per server. Have you heard about it?".
Yeah ... I think I did have heard about that .... ;-)
I don't think he read this anywhere in any official IBM / VMware document. It was just his perception. And perception, for him, is reality.
Massimo.

Typo.
>Since it runs at a it will
>be able to support more vm's
>per server
Should read:
Since it runs at a lower level it will be able to support more vm's per server

I didn't like having to dedicate an entire machine to test ESX 3i beta so, with help from the VMware community, I was about to virtualize it.
To show others how it can be done, I created a 16 minute video titled-
How to run VMware ESX Server 3i Beta inside VMworkstation

It is available at my website in Flash, Windows Media, and IPOD formats.
