Well, KVM_CLOCK obviously:
KVM_CLOCK
bool "KVM paravirtualized clock"
select PARAVIRT
select PARAVIRT_CLOCK
Turning on this option will allow you to run a paravirtualized clock
when running over the KVM hypervisor. Instead of relying on a PIT
(or probably other) emulation by the underlying device model, the host
provides the guest with timing infrastructure such as time of day, and
system time
