Unable to access Apache httpd virtual host

I am new to linux and I can install my LAMP server on Manjaro. Got it all, but now I'm having issues setting up the virtual host. I used httpd and commented out "include conf/extra/httpd-vhosts.conf" in /etc/httpd/conf/httpd.conf . But after editing httpd-vhosts.conf the host is not reachable . After searching the web for a solution, the latest information I got was,

# Virtual Hosts
#
# Required modules: mod_log_config

# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.4/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#

NameVirtualHost *:80

<VirtualHost *:80> 
    ServerAdmin [email protected] 
    DocumentRoot "/srv/http/sami" 
    ServerName dummy.local 
    ErrorLog "/srv/http/sami/dummy-host.example.com-error_log" 
    CustomLog "/srv/http/sami/dummy-host.example.com-access_log" common 
</VirtualHost>

<VirtualHost *:80> 
    ServerAdmin [email protected] 
    DocumentRoot "/srv/http" 
    ServerName localhost 
    ErrorLog "/srv/http/error-log" 
    CustomLog "/srv/http/access-log" common 
</VirtualHost>

But dummy.local fails to load and says,

Unable to access the site
dummy. The local server IP address could not be found.
