Intel NIC not detected after reboot

Jump to solution

Hello all.

One of my lab devices decided to dislike the Intel dual port NIC out of the blue after it was restarted. The card is listed on the HCG, supported via both e1000e and ne1000 VM modules, and is listed under lspci. And yet, ESXi 6.7 tells me no supported NIC cards are available. The NIC works on another system, so it is not a hardware fault. Both ports are connected and green, with their matching switch ports up.

VMWare ESXi 6.7.0 (VMKernel Release Build 8169922)

My NIC is exactly this - VMware Compatibility Guide - I/O Device Search

... card was made Pass-through via configuration. I had to edit /etc/vmware/esx.conf and change the interfaces from "passthru" to "vmkernel". Rebooted and back in business.
