The typical Vagrant setup will mount your Mac (project) folder in the 
virtual machine.

This means on the Mac it’s a 100% local file system with all the 
advantages that this brings, yet the files are still instantly 
accessible from the virtual machine.

Either the remote machine will inform the client about file systme 
changes (mounting a Mac via AFP does support this) or alternatively the 
client will have to poll the remote server to test if there are changes 
(as would be required in your case). I would be surprised if libkqueue 
includes code to do regular polling.

As indicated above, a workaround is to have the virtual machine mount a 
folder from your Mac.
