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:
I clicked file and then Host Network Manager
In the screen that appears I then clicked Create, to create a new Host Only Network.
I then right clicked on the VM i wanted to start and clicked settings.
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.
