Right. If booted Xen, I see this, which looks fine to me (this is
currently Xen 4.12.2):

# xl dmesg |grep time
(XEN) [00018d6c323bf350] Platform timer is 14.318MHz HPET  <===========
(XEN) [   22.097647] TSC deadline timer enabled
(XEN) [   23.068865] mwait-idle: lapic_timer_reliable_states 0xffffffff
(XEN) [   27.316536] mcheck_poll: Machine check polling timer started.
