No, ifconfig says xn0:
xn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
Also in dmesg.boot:
xn0: <Virtual Network Interface> at device/vif/0 on xenbusb_front0
xn0: Ethernet address: 00:16:3e:XX:XX:XX
xenbusb_back0: <Xen Backend Devices> on xenstore0
xn0: backend features: feature-sg feature-gso-tcp4
So it's xn0 in my case, not xe.
