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
Our virt-hosting systems all use bridges and I have the following setup for eth0 and br0
# ifcfg-eth0 NAME="eth0" TYPE=Ethernet ONBOOT=yes NETBOOT=yes BRIDGE="br0" UUID="<fill in uuidgen here>" HWADDR="<fill in mac address here>"
# ifcfg-br0 NAME="br0" DEVICE="br0" ONBOOT=yes NETBOOT=no UUID="<<fill in uuidgen here>>" IPV6INIT=no BOOTPROTO=none IPADDR="<< fill in ip address >>" NETMASK="<< fill in netmask >>" GATEWAY="<< fill in gateway >>" TYPE=Bridge NAME="br0" DNS1="<< fill in dns1 >>" DNS2="<< fill in dns2 >>" STP="no"
On EL8 systems it changes somewhat. If you just wants a bridge with no ip address associated with it.. leave those out. Some switches need that
