Let's take a further step. Attached patch is a __draft__ patch to collect statistics related with timer interrupts & timer fns. Can you apply it, rebuild the xen hypervisor code, then do "xm debug 9; sleep 20; xm debug 9; xm dmesg > xmdmesg.log" in both dom0 only & 1 HVM cases. Let's have a look on the timer statistics first.
