Windows 10 - Failed to attach the network LUN during Vagrant Provision

Hello everyone,

Provisioning the vagrant machine in a Windows 10 machine with Virtual Box Versión 6.0.10 r132072 has failed with the following message:

==> mongodb-m042: Booting VM...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "87da97c6-3045-4fbc-a5da-5592cb80d22c", "--type", "headless"]

Stderr: VBoxManage.exe: error: Failed to open/create the internal network 'HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter #2' (VERR_INTNET_FLT_IF_NOT_FOUND).
VBoxManage.exe: error: Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND)
VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole

What could I do? Maybe the problem is the “recent” version of VirtualBox I have installed.

Vagrant up –provision fails


Thank you.

I also followed this link in VirtualBox.
It seems to be required a reset of a certain flag in one of the Adapters that the new machine uses.
