Quick one - have you been able to get the "test-arm-64le-example"
application to run?  So far Xen gives me the following error:

(XEN) ****************************************
(XEN) Panic on CPU 0:
(XEN) Unable to copy the kernel in the hwdom memory
(XEN) ****************************************

I wanted to check with you before starting to dig into it.
