Configuring dnsmasq as PXE Server for ESXi

07.09.2020 by William Lam // 2 Comments

One really cool thing that I came to learn while setting up the infrastructure to network boot the latest Raspberry Pi 4 was the use of dnsmasq, which I have used in the past but I did not realize it could do so much more. In addition to providing DNS services, it can also be configured to run TFTP and provide DHCP capabilities which can then be used to support PXE installations.

Another neat feature of dnsmasq is ability to proxy to an existing DHCP server which is extremely useful for anyone with an existing DHCP infrastructure. Given the simplicity of dnsmasq and having already set this up for the rPI, I figure it would also be useful to take folks through in setting up dnsmasq to also support ESXi installations over PXE, since this still comes up from new folks just getting started with ESXi kickstart automation.

For more details about PXE installation of ESXi, I highly recommend this whitepaper and although it states 6.0, the concepts and configurations are still applicable to the latest ESXi 7.0 release.

Five of my favorite enhancements in vSphere 7

06.30.2020 by William Lam // 2 Comments

It is very easy to focus on the speeds and feeds of a new major vSphere release such as vSphere 7 which also includes a TON of new and exciting capabilities. However, often times it is the tiny improvements that has the most significant impact to our end users, especially when it comes to usability and operations. In fact, this was further reinforced by Frank Denneman's post on the Reddit with similiar observations.

I have been using vSphere 7 since it was released back in April and I have been discovering a number of new vSphere UI enhancements that has really delighted my overall user experience. I had been sharing these enhancements on Twitter, but figured it was worth a blog post given most of these features were not well known.

Do you have a favorite new feature in vSphere 7 that might not be well known? If so, share by leaving a comment below.

1. Enhanced VM Summary

I’m really digging the new VM Summary view in the #h5client with #vSphere7, especially with details about any snapshots you might have running! My only pet peeve is the gap of space at the very top /cc @APrabhudev pic.twitter.com/IRofUvMpaQ

2. Update and Patch Notifications

First patch release for vSphere with Kubernetes is now available

See Release Notes for more details https://t.co/QxDYa7rmTr

Its also really cool to see the vSphere UI is also aware of the update and has nice notification along w/link to RN 🙂 pic.twitter.com/xKYJPfQRGs

3. ESXi Firmware and Driver View

I just noticed the new enhancements made to ESXi “Hardware” view in #h5client for vSphere 7. Really digging the Firmware section which cleanly & clearly lays out the various devices/components along the specific driver claiming each device which is super useful! pic.twitter.com/OsNPUDaPuj

4. ESXi Installation Date + Software Package Details

Pleasantly discovered two new #vSphere7 UI features this morning while using the #h5client

Navigate to ESXi Host->Configure->System->Packages

Can now see ESXi Install Date + all VIB/Components nicely listed!

5. Terminate "stuck" VM

In rare case you have pesky VM that is “stuck”, it looks like we’ve now exposed the Kill (Terminate) cmd under the VM Power Operations. No need for SSH/ESXCLI

I initially noticed this with the latest #VMWonAWS release but looks like its made its way into vSphere 7.0b too!

Here are two additional non-UI features that I came to learn about in vSphere 7 that you might also be interested in: Support for HTTPS using wget on ESXi and Guest Customization support for Instant Clones.

How to patch Intel NUC 10 with latest ESXi 7.0 update?

06.28.2020 by William Lam // 33 Comments

vSphere 7.0b was just released last week and one of the important fixes was to resolve an issue where Nested ESXi VMs were crashing upon powering on an inner-guest VM. This looks to have also affect newer generations of CPUs including Intel's 10th Gen Comet Lake which is also found in the latest 10th Gen Intel NUCs (Frost Canyon).

A number of folks quickly found that if you simply applied the ESXi 7.0b patch, an unexpected behavior occurred on the 10th Gen Intel NUCs and the onboard networking was lost upon a reboot. This occurs as the original ne1000 driver which had been replaced with a newer version found within ESXi 7.0b no longer recognizes the onboard Intel NIC. The solution is quite simple, create a new Image Profile that contains the Intel NUC NIC Driver.

Several of you have asked for instructions and although this is a pretty common vSphere workflow, I have documented the two supported options using the vSphere Image Builder utility but there are definitely other methods which will have the same results. If you have access to a vCenter Server 6.7 or newer, I recommend using the Image Builder UI. If vCenter Server access is not available, then you can use Image Builder with PowerCLI, however you will need to have access to a Windows machine as the Image Builder cmdlet is not supported with PowerCLI Core.

Note: There is currently a known bug with the Image Builder UI when using vSphere 7 which will prevent you from authoring a new Image Profile. A workaround would be to deploy a VCSA 6.7 which does not have this issue when looking to use the Image Builder UI.
