For special purpose i need multi bridge hostmachine
xenbr0
eth0 (for lan and guest lan domU)
xenbr1
eth1 (for wan)
xenbr2
for standalone domU
domU-0.cfg
kernel = "/home/xen/kernel/vmlinuz-2.6.12-xenU"
memory = 64
name = "domU-0"
ip = "192.168.20.249"
netmask = "255.255.255.0"
gateway = "192.168.20.5"
hostname = "domU-0"
nics = 1
vif = ['mac=AE:DA:C0:A8:14:F9','bridge=xenbr0']
disk = ['phy:vg01/domU-0,sda1,w']
root = "/dev/sda1 ro"
domU-2.cfg
kernen = "/home/xen/kernel/vmlinuz-2.6.12-xenU"
memory = 64

i must change manually vif assigniment
brctl delif xenbr0 vif12.0
brctl addif xenbr2 vif12.0

ALL OK

Investigation:
log of /etc/xen/scripts/vif-bridge
vif-bridge up vif=vif12.0 domain=squirrelmail mac=ae:da:c0:a8:14:fb
bridge=xenbr0
vif-bridge up vif=vif12.1 domain=squirrelmail mac=aa:00:00:1f:d2:ce
bridge=xenbr2
it pass xenbr2 only for .1 interfaces for xenbr0
FINAL:
xend create and associate bridge for vifX.0 based on
/etc/xen/xend-config.sxp
create and associate bridge for vifX.1 based on
/etc/xen/auto/domU.cfg
this work only for 1 bridge configuration
Now i make a orrible workaround with vif-bridge script
but it should be corrected on xend daemon (i suppose)
bye
