I haven't done bridging on CentOS but, in the setups I've done, you need to associate a physical NIC such as eth0 with the bridge.

Subject: [EXTERNAL] Bridge network for virt-manager
CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe.
Hello. I desire to get bridge network working using virt-manager.
Centos 7 and centos 7 guest.
>From researching I think I need to have a ifcfg-br0 file like this ?
cat ifcfg-br0
DEVICE=nm-bridge0
STP=no
TYPE=Bridge
BOOTPROTO=none
IPADDR=192.168.1.8
PREFIX=32
GATEWAY=192.168.1.1
IPV6INIT=no
NAME=br0
ONBOOT=yes
DELAY=0
Is that for sure needed ? The use that nm-bridge0 as the network name?
I dont want to mess up my current setup.
Thanks,
Jerry
