EDIT: If you have a line in the domU configuration file that already has a vif 
stated, which will probably be the case (eg. vif=['bridge=xenbr0']) you can 
just add the following configuration for two network connections by doing 
something like: 

vif=['bridge=xenbr0','bridge=xenbr2']

I have a similar setup for an iSCSI storage network where one of the NICs on 
the dom0 is connected to the iSCSI network and allows connectivity to the domU 
through a special network bridge "iscsibr0" which I add to the config file as I 
showed above.
