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
