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
Use the virt-manager to create the desired bridge. It will end under
/etc/libvirt/qemu/networks/. And there probably exists already a
# cat /etc/libvirt/qemu/networks/default.xml
