Hi, I am using same setup. It just my guess because no response to key ctrl+a input. SoC has 8250 compitible UART.I will print character in receive handler of UART in Xen. Do we have any other hook test this? One more thing, is big-little supported in xen? How Xen distribute load among the CPUs or Xen only run in context of the guest only? In my setup Dom0 use energy aware scheduler.

So unless you have a completely new setup, Xen is definitely running. However, what may happen is the serial driver in Xen does not receive input characters. One of the first test would be to check whether the driver effectively receive characters.
