What is the problem when creating virtual hosts in apache2?

Question

Apache HTTP Server

I have apache2 openuse installed, trying to create a virtual host like on ubuntu, with the following config ServerAdmin
[email protected]
ServerName test.dev
DocumentRoot /srv/www/vhosts/test.dev/public_html
ErrorLog /var/log/apache2/test .dev-error_log
CustomLog /var/log/apache2/test.dev-access_log combined
This config is in /etc/apache2/vhosts.d/test.dev.conf. After restarting the server, the site test.dev was not found, but not a stub file is available at the address localhost, but test.dev. If you add another site, then the new one will be displayed by localhost, and not test.dev. Something went wrong?
