Using vSphere Auto Deploy to Netboot ESXi onto Apple Mac Hardware

01.17.2017 by William Lam // 4 Comments

Last week I published an article that demonstrated for the first time on how to netboot an ESXi installation onto Apple Mac Hardware. As you can imagine, this was very exciting news for our VMware/Apple customers, who historically have not had this capability before. Customers can now automate and install ESXi over the network onto their Apple Mac Hardware just like you would for other non-Apple hardware.

With the ability to boot ESXi over the network for Apple Mac Hardware, it is now also possible for customers to take advantage of the vSphere Auto Deploy feature. Auto Deploy allows customers to easily and quickly provision ESXi hosts at scale and integrates directly with vCenter Server to automatically join and apply specific defined host configuration policies. This is a great time to check out Auto Deploy, especially with all the new enhancements that were introduced in vSphere 6.5 like custom script bundles for example.

Below are the instructions on how to setup Auto Deploy to work with Apple Mac Hardware.

How to Netboot install ESXi onto Apple Mac Hardware?

01.13.2017 by William Lam // 13 Comments

The ability to perform an ESXi Scripted Installation over the network has been a basic capability for non-Apple hardware customers since the initial release of classic ESX. However, for customers who run ESXi on Apple Mac Hardware (first introduced in vSphere 5.0), being able to remotely boot and install ESXi over the network has not been possible and customers could only dream of this capability which many of us have probably taken for granted.

Unlike traditional scripted network installations which commonly uses Preboot eXecution Environment (PXE), Apple Mac Hardware actually uses its own developed Boot Service Discover Protocol (BSDP) which ESXi and other OSses do not support. In addition, there are very few DHCP servers that even support BSDP (at least this may have been true 4 years ago when I had initially inquired about this topic). It was expected that if you were going to Netboot (equivalent of PXE/Kickstart in the Apple world) a server that you would be running a Mac OS X system. Even if you had set this up, a Netboot installation was wildly different from a traditional PXE installation and it would be pretty difficult to near impossible to get it working with an ESXi image. With no real viable solution over the years, it was believed that a Netboot installation of ESXi onto Mac Hardware just may not be possible.

tl;dr - If you are interested in the background to the eventual solution, continue reading. If not and you just want the goods, jump down a bit further. Though, I do think it is pretty interesting and worth getting the full context 🙂

UEFI PXE boot is possible in ESXi 6.0

10.09.2015 by William Lam // 21 Comments

A couple of days ago I received an interesting question from fellow colleague Paudie O'Riordan, who works over in our Storage and Availability Business Unit at VMware. He was helping a customer who was interested in PXE booting/installing ESXi using UEFI which is short for Unified Extensible Firmware Interface. Historically, we only had support for PXE booting/installing ESXi using the BIOS firmware. You also could boot an ESXi ISO using UEFI, but we did not have support for UEFI when it came to booting/installing ESXi over the network using PXE and other variants such as iPXE/gPXE.

For those of you who may not know, UEFI is meant to eventually replace the legacy BIOS firmware. There are many benefits with using UEFI over BIOS, a recent article that does a good job of explaining the differences can be found here. In doing some research and pinging a few of our ESXi experts internally, I found that UEFI PXE boot support is actually possible with ESXi 6.0. Not only is it possible to PXE boot/install ESXi 6.x using UEFI, but the changes in the EFI boot image are also backwards compatible, which means you could potentially PXE boot/install an older release of ESXi.

Note: Auto Deploy still requires legacy BIOS firmware, UEFI is not currently supported today. This is something we will be addressing in the future, so stay tuned.

Not having worked with ESXi and UEFI before, I thought this would be a great opportunity for me to give this a try in my homelab which would also allow me to document the process in case others were interested. For my PXE server, I am using CentOS 6.7 Minimal (64-Bit) which runs both the DHCP and TFTP services but you can use any distro that you are comfortable with.
