Centos 6.6 create bridged network

Centos 6.6 create bridged network

I am using network 192.168.10.0/24 with my gateway of 192.168.10.1 and DNS of 192.168.10.1
I have my Centos server with IP Addr of 192.168.10.100
I am using this bridge for my KVM quest images so they can be on the same network. They will use the br0 interface when setting them up
