Changing the MAC address of the VirtualBox Host-Only Adapter

[mpack]

Sorry, 5 day 5 post limit for new accounts here.

I'm not aware of any such limit, in fact I'm quite certain that no such limit exists.

Changing the MAC address of a network service is a non sequiter. The dialog for changing the Host Only IP address, on the other hand, is easily found in preferences, though I've never needed to try it myself.

Did you read the posts above yours? It has the solution.

This is the adapter I'm referring to, unfortunately there's no advanced tab with network settings like other adapters have. It seems some people have gotten this adapter to work by adding the registry key of "MAC" or "NetworkAddress" wwith the 48bit MAC and it take effect.

It does not seem to work, I have tried on multiple computers with a few reinstalls.

Also, " Open your registry (start-->run-->regedit) and search for 08xxxxxxxxxx (without hyphen), " on that part of the solution, I can not find any of my MAC address within the registry because it is not there, but I can go to the HKLM area where the network adapters are and find the VB adapter.

I found a bit more info, but no solution yet.

On my computer, using VirtualBox Manager v5.1.6 r110634, the Host-Only MAC address is stored as REG_BINARY data at the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nsi\{eb004a11-9b1a-11d4-9123-0050047759bc}\10\0000000f00000600

Regedit doesn't allow searching for binary data. To work around this limitation, I exported the all data from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet to a C:\CurrentControlSet.reg file, then opened that file in a text editor and searched for a subset of the MAC address.

The MAC address I was searching for was: 0A-00-27-00-00-12.

I searched for a subset of this MAC address in the binary data: 0a,00,27

Code: Select all

    6f,6e,69,63,01,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,06,00,0a,00,27,\
    00,00,12,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\
    00,00,00,00,06,00,0a,00,27,00,00,12,00,00,00,00,00,00,00,00,00,00,00,00,00,\
    00,00,00,00,00,00,00,00,00,00,00,00,00,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,ff,\

I tried editing this MAC address in the Binary data, and rebooting. But the MAC address did not change.

Can somebody explain to me the meaning of this exercise? What's the purpose of changing the HostOnly address of the host adapter? In details if you don't mind...
