Create an ESXi 6.0U2 installation ISO with Realtek 8168 Drivers

Posted on Updated on

Folks — I need your help. I’ve been running this blog for 8 years and my blog has never broke the top 100 vBlogs.  It’s been a bit disappointing but I write my blog for you the reader.  If you like this blog post then its time to vote for for Top vBlog of 2018 —  Thank you for your support — Matt

Now on to the blog you came for….

ESXi no longer supports Realtek Network drivers nor are they included on the installation ISO.  However, if you want to install ESXi with the Realtek drivers, then users will have to create a custom ISO. Keep in mind these drivers are NOT supported by VMware and should be used as your own risk.  Normally, I would use my trusty ESXi-Customizer GUI program but it is no longer supported for ESXi 6.  In replacement they offer a CLI supported program. However, instead of learning another 3rd party tool I’d rather rely on the VMware tools provided to me. VMware enables users to create custom ISOs via PowerCLI and in this blog I’ll explain how I used PowerCLI create my ISO. Keep in mind these are the steps that worked for me, your environment may vary.

— Required Tools and Files —

To get started you will need two files and PowerCLI Installed on a Windows PC.  You can skip these steps if you have the ESXi Offline Bundle, PowerCLI installed, and the RealTek Drivers.

STEP1: File 1: Download VMware 6.0U2 Offline Bundle ZIP >>

STEP 2: File 2: Download RealTek 8186 Offline bundle >>

STEP 3: If you haven’t yet download and install PowerCLI >>

Tip: If you don’t know PowerCLI try starting here

STEP 4: Next Place the files from Step 1 and 2 into c:\tmp folder


Now that you have your files and PowerCLI ready follow these steps.  For step below I included a screenshot and the actual command allowing you to copy, paste, and edit into your environment.

STEP 1: Open PowerCLI (Tip: If you don’t know PowerCLI try starting here)

STEP 2: Add ESXi 6.0u2 and RealTek8186 products to the local Software Depot (Tip: All commands below assume your files are located in the c:\tmp folder)

Add-EsxSoftwareDepot C:\tmp\

Add-EsxSoftwareDepot C:\tmp\

STEP 3: Confirm the products are in the depot


STEP 4:  List out the ESXi Image Profiles


STEP 5:  Create a Clone Image to be modified – Ensure you are targeting the “ESXi…..standard” profile from step 3

New-EsxImageProfile -cloneprofile ESXi-6.0.0-20160302001-standard -Name “RealTek8186a”

Forward-Looking Tip: Whatever name you choose it will show up in your boot ISO

STEP 6: Set the Acceptance Level to Community Supported – Remember RealTek is unsupported by VMware

Set-EsxImageProfile -Name RealTek8186a -AcceptanceLevel CommunitySupported

For ImageProfile Enter – RealTek8186a

STEP 7: Ensure the RealTek net55-r8186 driver is loaded from the local depot (Screenshot shortened)


STEP 8: Add the RealTek software package to the profile


ImageProfile: RealTek8186a

SoftwarePackage[0]: net55-r8168 8.039.01-napi

Tip: For the SoftwarePackage you MUST enter the full name, if you just use the short name it will not work

STEP 9: Validate the RealTek drivers are now part of the RealTek8186a Profile (Screenshot shortened)

(Get-EsxImageProfile “RealTek8186a”).viblist

STEP 10: Export the profile to an ISO

Export-EsxImageProfile -ImageProfile “RealTek8186a” -ExportToIso -FilePath c:\tmp\RealTek8186a.iso

And that’s it… You should find your new ISO in the c:\tmp folder.  From here you can burn your ISO to a media of your choice or boot the ISO via ilo, iDRAC, virtual media etc.

If you like my ‘no-nonsense’ blog articles that get straight to the point… then post a comment or let me know… Else, I’ll start writing boring blog content.

    Thankz Mat , this is just what i needed. Been looking for almost 2 hours before I found your tutorial.
    Indeed the “no-nonse, straight to the point” approach is in my opinion the best. Lots should take learning from this.
    I sure will come back to check the rest of your blog. First gonna install ESX.

    Hi, Where would I find an ISO file with the realtek drivers already injected. that would be most useful…

      I believe, and don’t quote me on this, the last time RealTek was part of the VMware ISO was vSphere 5.1. After that the RealTek Drivers were no longer supported with ESXi and everyone with a non-production Home labs have been injecting them ever since. I don’t recall why they were removed from the vSphere line and I have not heard of their return. Best bet for compatibility is to buy Intel or Broadcom NICs.

    please provide the iso image you have created. That way will be super easy

      Thanks for the comment. Supplying a ISO that is modified is a great idea… However, it would be a violation of licensing and re-distributions agreements so legally I cannot.

    this is the best, quick tutorial of crafting custom iso for ESXi.
    i use this for my 6.5 version.

    I hope will find success.
