How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

1. Configure server: Nginx

Create the certificate:

$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/nginx-selfsigned.key -out /etc/ssl/certs/nginx-selfsigned.crt

Create a strong Diffie-Hellman group:

$ sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

Configuring the qcow2 size cap is possible in the current versions:
