Yep, I keep mine simple too, in Redhat/Centos/Fedora terms my networking is

# cat /etc/sysconfig/network-scripts/ifcfg-virbr0
DEVICE=virbr0
TYPE=Bridge
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
IPADDR0=192.168.1.125
PREFIX0=24
GATEWAY0=192.168.1.1
DNS1=192.168.1.1
DEFROUTE=YES
IPV6INIT=no
NM_CONTROLLED=no

# cat /etc/sysconfig/network-scripts/ifcfg-em1
DEVICE="em1"
BOOTPROTO=none
ONBOOT="yes"
NM_CONTROLLED=no
HWADDR=00:1E:8C:BC:53:36
TYPE=Ethernet
BRIDGE=virbr0
NAME="System em1"
UUID=1dad842d-1912-ef5a-a43a-bc238fb267e7

# cat /etc/rc.d/rc.local
ifup virbr0
ifup em1
ip route add default via 192.168.1.1

then in each domU's .cfg file

vif = [ 'mac=00:16:36:xx:yy:zz, bridge=virbr0' ]
