Black Screen when connecting a Monitor to Intel NUC running ESXi

When you are using an Intel NUC or other consumer hardware to run ESXi and connect a monitor to access the DCUI console, you see a black screen only. If you do not have a monitor connected during the boot process, you can't access the screen later. The screen will remain black, making troubleshooting impossible.

In Homelabs you usually do not have a monitor connected to all of your servers but in some cases (ESXi crashes or you need to reconfigure network settings) you want to connect a monitor to your system. A simple trick can help in that situation. Read more »

Realtek NIC and ESXi 7.0 - Use Passthrough to make use of the Adapter

Realtek Adapters are very common in consumer hardware and SFF systems. Using SFF systems to run ESXi is a good option for home labs as they are inexpensive and have a low power consumption. Unfortunately, the Realtek RTL8168, which is used in Asus PN50 or ZOTAC ZBOX Edge for example, is not supported in ESXi. The problem can be solved with a community created driver in ESXi 5.x and 6.x but not in ESXi 7.0, due to the VMKlinux driver stack deprecation.

You can work around the problem by using an USB based NIC to manage ESXi. Using USB NICs works fine and stable, but at this point the embedded NIC is useless. If you want to use it, you can use passthrough to add it to a virtual machine.
