The mac address of a vifX.Y device in dom0 is almost always
fe:ff:ff:ff:ff. This is the largest valid MAC address and is chosen
because the bridge will take on the lowest MAC of all it's ports under
some circumstances so using fe:..... ensures it is never the MAC of a
VIF.

Presumably the original poster wants the MAC of the ethX device within
the guest?

/etc/xen/scripts/vif-nat has an example of how to do this:

# grep mac /etc/xen/scripts/vif*
/etc/xen/scripts/vif-nat:  mac=$(xenstore_read "$XENBUS_PATH/mac")
