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
