Example 1, eth0 is a trunk port to VLAN 11 and 12, while eth1 is a trunk 
port to VLAN 13 and 14.
auto xenbr11
iface xenbr11 inet manual
  address XX.XX.XX.XX
  netmask 255.255.255.0
  gateway XX.XX.XX.XX
  bridge_ports eth0.11
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0

auto xenbr12
iface xenbr12 inet manual
  bridge_ports eth0.12
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0

auto xenbr13
iface xenbr13 inet manual
  bridge_ports eth1.13
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0

auto xenbr14
iface xenbr14 inet manual
  bridge_ports eth1.14
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0


Example 2, eth0 and eth1 are bonded and the bond is used as trunk for 
VLAN 11,12,13,14:
auto bond0
iface bond0 inet manual
  slaves eth0 eth1
  bond_miimon 100
  bond_updelay 100
  bond_downdelay 200
  bond_mode 802.3ad
# make sure to have the right bond_mode

auto xenbr11
iface xenbr11 inet manual
  address XX.XX.XX.XX
  netmask 255.255.255.0
  gateway XX.XX.XX.XX
  bridge_ports bond0.11
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0

auto xenbr12
iface xenbr12 inet manual
  bridge_ports bond0.12
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0

auto xenbr13
iface xenbr13 inet manual
  bridge_ports bond0.13
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0

auto xenbr14
iface xenbr14 inet manual
  bridge_ports bond0.14
  bridge_stp off
  bridge_maxwait 0
  bridge_fd 0


Note: no individual ethX or ethX.NN setup. The reference in the bond and 
bridge sections is enough.
The Dom0 IP is set up on the bridge, not on the ethX port not on the bond.

Greetings.
