Just a heads up for anyone who’s curious to upgrade to the new MacOS. Currently VirtualBox still seems to lack support for it meaning your Trellis projects won’t work. My project which worked on Big Sur now shows this on vagrant up.
There was an error while executing `VBoxManage`, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below. Command: ["hostonlyif", "create"] Stderr: 0%... Progress state: NS_ERROR_FAILURE VBoxManage: error: Failed to create the host-only adapter VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterfaceWrap, interface IHostNetworkInterface VBoxManage: error: Context: "RTEXITCODE handleCreate(HandlerArg *)" at line 95 of file VBoxManageHostonly.cpp
