It sounds like you are using Ubuntu, the issue here is likely that you have
network manager installed and it doesn't define the network devices in
/etc/network/interfaces.

This is probably an issue of Xen on <your distro> not being network manager
aware.

You can define your own bridges and that will work fine, but you have
to make sure
all your configurations are updated (i.e. guest configs and if you
specify anything in
the xend config, etc.)

Hope that helps,
