I found this annoying too, and asked the question a little while ago on here. Answer was: 'vagrant reload --provision' which isn't perfect because it leaves traces of old sites and sometimes duplicates some entries in /etc/nginx/sites-enabled but mostly works fine.

ok cool maybe i'll try that next time...thanks :)

The correct method is to use 'serve' (this shell executable is built into homestead) Please refer to the documentation at : http://laravel.com/docs/homestead?version=4.2 (at the very end of the page)

'serve' is a bit of a short term fix (and feels wrong) and assumes you've already shared the folders you need to with Homestead. If you want to add completely new folder mappings but don't want to destroy then 'vagrant reload --provision' does work.
