error cause

Could not find Host Interface Networking driver! Please reinstall can’t find the host interface network driver! Please reinstall

then it occurred to me that before I thought the network connection inside the network card too many , in the device management > also removes the VirtualBox virtual network card driver.

because the driver is gone and you cannot create a virtual network card, start the virtual machine with the vagrant up command and throw the above error message.

solution

find XXX \Oracle\VirtualBox\drivers\network\netadp6 directory, file as follows.
right-click VBoxNetAdp6. Inf file, select install

3. Now execute vagrant up and the virtual machine can be started normally!
