Apache Virtual host setup configuration in localhost for multiple magento sites

i have two magento 2 instances in my virtualbox ubuntu server.
1st one is new installation magento2.3 located at
/var/www/html/, it is working find and accessible from browser using ip 127.0.0.1 or localhost

The 2nd instance is cloned version of production site magento 2.2.9, located at /var/www/html2/. I’m able to run bin/magento commands from the command line, however i’m not able to access the site from browser.

How do i modify the configuration file for hosts at /etc/apache2/sites-available/ to work with multiple magento sites?
