After updating Vagrant to the latest version I get these complaints in the terminal when running vagrant up in the trellis directory. Perhaps some configuration needs to be updated?
Vagrant has detected a configuration issue which exposes a vulnerability with the installed version of VirtualBox. The current guest is configured to use an E1000 NIC type for a network adapter which is vulnerable in this version of VirtualBox. Ensure the guest is trusted to use this configuration or update the NIC type using one of the methods below:
