dnsmasq

# sudo apt-get install dnsmasq
# echo "address=/.dev/127.0.0.1" >> /etc/dnsmasq.conf

In case you have other static vhosts in your nginx installation use

listen 80 default_server;

to catch unknown virtual hosts by this configuration.

Thank you. After two days of failed tests your solution saved me.

Arigatow! 😸 💯

additionally you should set

fastcgi_param SERVER_NAME $servername;

this will set in php "$_SERVER['SERVER_NAME']" variable to proper host name instead of plain "$servername"

Nice thing, sadly you need LUA for this to work.
