I use the following setup:

*** ifcfg-eth0 ***
DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

plus identical config files for eth1 etc.

*** ifcfg-bond0 ***
DEVICE=bond0
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
BRIDGE=br0
BONDING_OPTS="miimon=1000 mode=4"

*** ifcfg-br0 ***
DEVICE=br0
TYPE=Bridge
BOOTPROTO=none
ONBOOT=yes
DELAY=0

*** ifcfg-bond0.100 ***
DEVICE=bond0.100
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
BRIDGE=vlan100
VLAN=yes

*** ifcfg-vlan100 ***
DEVICE=vlan100
TYPE=Bridge
BOOTPROTO=none
ONBOOT=yes
DELAY=0
#Add IP address here if required
#IPADDR=
#NETMASK=
#NETWORK=
#BROADCAST=
#GATEWAY=

Where the number after the dot in ifcfg-bond0.100 is the vlan id in the 
usual way. The vlan100 device would then be the bridge device to select 
for a kvm guest to get untagged traffic on vlan 100 to the guests nic.

Hope that helps.

Andrew
