Loving all the improvements (one U/0 kernel, improved balloon, primary eth not in bridget, ...) but trying to understand that last one.
What is this peth0 device that's in the xenbr0 bridge now?
sammy:/etc/xen# brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no vif5.0
