ubuntu – How to setup multiple websites on a virtualbox with apache?

I am trying to set up multiple websites, test and live, as subdomains in a ubuntu-server 22.04 as guest in a Virtualbox. I installed apache2, php and mysql. Then i adjust the Virtualbox via NAT for port forwarding and create a rule where host port is 8000 and guest port is 80. then i restart the machine and can reach the apache2 site in the browser with localhost:8000.
That is what i expected. Now i wish to configure two subdomains. I create a file website.conf with this text inside:

## Test
 <VirtualHost *:80>
   DocumentRoot /var/www/html/test/
   ServerName test.website.com
 </VirtualHost>

## Live
<VirtualHost *:80>
   DocumentRoot /var/www/html/live
   ServerName live.website.com
 </VirtualHost>

And set my /etc/apache2/apache2.conf

ServerName website.com

Then restart apache with systemctl.
After that, i configure /etc/hosts on the host

127.0.0.1:8000    website.com

Now i am trying to reach the websites via the browser.
I try test.website.com and live.website.com, but both say
“Server not found”
When i try localhost:8000 i get to the site behind test.website.com.

apache2ctl -t yields:

“Syntax OK”

apache2ctl -S yields:

VirtualHost configuration:
*:80                   is a NameVirtualHost
         default server test.website.com (/etc/apache2/sites-enabled/website.conf:2)
         port 80 namevhost test.website.com (/etc/apache2/sites-enabled/website.conf:2)
         port 80 namevhost live.website.com (/etc/apache2/sites-enabled/website.conf:8)

How can I enable both Subdomains?
