How to run xdebug on a virtual machine?

Question

PHP

For half a day I've been trying to make phpstorm and xdebug friends.
Given there is a virtual machine, on it ubunta nginx php and xdebuger
here are the settings in 20-xdebug.ini
zend_extension=xdebug.so
xdebug.profiler_enable=0
xdebug.profiler_enable_trigger=1
xdebug.remote_enable=1
xdebug.remote_host=192.168.122.177
xdebug.remote_port =9001
xdebug.remote_handler=dbgp
xdebug.idekey=PHPSTORM
xdebug.remote_autostart=1
xdebug.remote_connect_back=0
telnet 192.168.122.177 9001
Trying 192.168.122.177...
telnet: Unable to connect to remote host: Connection refused
which can be? I don't know where to look anymore.
here are all the settings output by phpinfo();
