You are right but the problem is
this wiki page
see just Ctrl+F following
"default bridge name in xen 3.2"

in the blue heading network-bridge
point number 6 says

"peth0 and vif0.0 are attached to bridge xenbr0. Please notice that in
xen 3.3, the default bridge name is the same than the interface it is
attached to. Eg: bridge name eth0, eth1 or ethX.VlanID "

note above they are saying in xen 3.3 default bridge name is same as
ethernet the interface is attached to I am using xen 3.2
so it should be xen-br0

my problem is I want to rename the default bridge eth2 for an experiment.
Which I am unable to.
