Issue

When I tried to run my virtual machine, it crashed and displayed the following error message.

Failed to open a session for the virtual machine XXXXX.
Failed to open/create the internal network 'HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter' (VERR_INTNET_FLT_IF_NOT_FOUND).
Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

Solution

This fatal error occurred because I disabled the VirtualBox Host-Only Network adapter. To resolve this issue, simply go to the Network Connections and enable it.

Win 10 - Network Connections - VirtualBox Host-Only Network
