This document provides steps to add a virtual network to a RHEL7 virtual machine using virt-manager. It involves opening virt-manager, editing the connection details, adding a new virtual network, specifying the IPv4 and IPv6 address ranges, selecting how it will connect to physical interfaces, and verifying the new virtual network by checking its interface and pinging its address.

1. How to add virtual network to RHEL7 Box ?

IPV6 Network
2016:2015:2014:2013::/64
Start Range: 2016:2015:2014:2013:0:0:0:0
End Range: 2016:2015:2014:2013:ffff:ffff:ffff:ffff
No. of host: 18446744073709551616

7. Step7 - Select how the virtual network replicate with which interface default NAT
