During the beta fase of vSphere 6 I was looking for a couple of workarounds for problems during installation process in my homelab. One of those problems is that (as with vSphere 5.5) certain not supported hardware are the onboard realtek NICs on the cheaper “homelab” motherboards. During this search I came across this workaround (login needed) by Andreas Peetz explaining a method to install the drivers onto the vSphere host(s) in your environment. Thanks Andreas, it worked well for me!!
