I checked the Microsoft list of supported adapters, and that said we should use the Intel NIC, not the Realtek NIC:
Supported Ethernet NICs for Network Kernel Debugging in Windows 8.1
However, in practice, the Realtek NIC seems to work better, so I recommend ignoring the Microsoft list and just trying the card(s) you have.
Plug in a NIC of your choice.
In Network Connections, disable all NICs you aren't using.

Find your computer's IP address and record it.
Right-click "Command Prompt" and cick "Run as Administrator".
In the User Account Control box, click Yes.
In the Administrator Command Prompt window, execute these commands, replacing the IP address with the IP address of your Host Windows 8 machine:
bcdedit /debug on
bcdedit /dbgsettings net hostip:192.168.1.170 port:50000 key:1.2.3.4
Note: the key used here is easy to use but not secure--using a longer,
more random, key is safer.
Then restart the Target computer. The boot menu will show "Windows 8 [debugger enabled]", if it is a multiboot system like the ones in S214.
Right-click "WinDbg (X64)" and click "Run as Administrator".
In the User Account Control box, click Yes.
Click File, "Kernel Debug".
On the NET tab, enter a key of
1.2.3.4
as shown below. Then click OK.
If a box pops up saying "Windows Firewall has blocked some features of this app", click "Allow access".
WinDbg shows a message: "Waiting to reconnect...".
If the message doesn't change in a few seconds, restart the Target computer again.
Make sure you can see the "Connected to Windows" message.
