Answer 1

Change the file a little

Listen 8081

<VirtualHost *:8081>
    DocumentRoot "C:/xampp/htdocs/sam"
    ServerName mydomainname.test
    ServerAlias mydomainname.test
    <Directory "C:/xampp/htdocs/sam">
    Options Indexes MultiViews FollowSymLinks
        AllowOverride All
        Order Deny,Allow
        Allow from all
    Options All
       Require all granted
    </Directory>
</VirtualHost>

Answer 2

It's /etc/hosts . And it does not accept ports and should look like: mydomainname.test 127.0.0.1
