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.

    I had the same issue after reinstalling Windows 10 and copying back my virtual machines and VirtualBox settings but this did not solved the issue. It is probably because network adapter was already present for me, but maybe slightly different from the one that I had in previous installation, also I had virtual machine network configured in bridged adapter, not host-only adapter.
    Anyway, in my case I simply fixed it by setting virtual machine network “Attached to” to “Not attached”, closing/saving settings and going back to virtual machine network settings to set it back to “Bridged Adapter”.
