bootloader = "/usr/bin/pygrub"
bootargs = "-q"
extra = " console=xvc0"
disk=[ 'phy:/dev/xen/centos5,xvda,w' ]
vif=[ 'bridge=br1' ]

the first time you bring up the br1, use
ifconfig

to get the mac address, then go add it back to your cfg
vif=[ 'bridge=br1,mac=vv:ww:xx:yy:zz' ]

this way your IP address will be fixed by your DHCP via mac.
