VirtualBox host only adaptor disappeared (Interface (‘VirtualBox Host-Only Ethernet Adapter’) is not a Host-Only Adapter interface (VERR_INTERNAL_ERROR) SOLVED

Hi there,

After recently updating Windows 10, none of my VMs in VirtualBox would power on. I kept receiving an error that read:

(Interface (‘VirtualBox Host-Only Ethernet Adapter’) is not a Host-Only Adapter interface (VERR_INTERNAL_ERROR) SOLVED

 

After looking around the settings of my Windows 10 machine I noticed that the host only adaptor was missing. To fix it I added a new adaptor by doing the following:

Step 1

I clicked file and then Host Network Manager

Step 2

In the screen that appears I then clicked Create, to create a new Host Only Network.

Step 3

I then right clicked on the VM i wanted to start and clicked settings.

Step 4

I then did the following:

  • Clicked on Network.
  • Selected the checkbox to enable Network adaptor.
  • Assigned the Host only adaptor I created.
  • I then clicked ok.

The VM then booted without issue.
