That's weird. You should also have some tap interfaces for HVM domains.
Do you remember to put "type=ioemu" on winxp's vif config line?

It says your bridge is called eth0

But xend.log says you're using xenbr0 in your config file.

The befault network-bridge script should create a bridge called xenbr0.
If you use a custom bridge script, you should modify your domU config
accordingly. It should be (on your setup) something like

vif = [ 'type=ioemu, mac=SOME_FIXED_MAC_ADDRESS_HERE, bridge=eth0' ]
