The issue is that, when booting to Xen, hpet is not advertised as an available 
clocksource, AND reports the hpet boot error pointed out by Randy.

Following 

  
https://wiki.xen.org/wiki/Xen_power_management#HPET_as_broadcast_timer_source_.28clocksource.29_.3D

there's discussion there re: 'if HPET is available / not missing'.

It appears to be available only booting to non-Xen.

What specific indication does one look for that Xen's using available hpet?
