From: Sebastien Boeuf <sebastien.bo...@intel.com> Cloud Hypervisor doesn't emulate the legacy 8254 PIT, which is why instead of relying on it as the timer UEFI services, rely on the XenTimerDxe implementation. This is not Xen specific, as it simply uses the local APIC timer triggering interrupts on the vector 32.
