Setting up Xdebug in a virtual machine?

Question

virtual box

Hello!
Host: Win 10
Guest: Kubuntu 18.04
VM: VirtualBox
PHPStorm is running in the virtual machine, a browser is running on Windows, you need to set up XDebug.
Here's what I did:
1. Set up a network between machines through NAT and a network bridge
2. Set up Xdebug:

zend_extension=xdebug.so
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.idekey="PHPSTORM"
xdebug.remote_connect_back=1
xdebug.remote_host=192.168.31.13 // Адрес хоста (win 10)

3. Configured PHPStorm:

The Chrome browser has the Xdebug extension, enabled.
Tell me what else needs to be done to make it work?

Answer 1

I did port forwarding 9000 in VirtualBox and it worked!
