[PATCH v3 0/4] KVM: LAPIC: Implement Exitless Timer

Dedicated instances are currently disturbed by unnecessary jitter due to the emulated lapic timers fire on the same pCPUs which vCPUs resident. There is no hardware virtual timer on Intel for guest like ARM. Both programming timer in guest and the emulated timer fires incur vmexits. This patchset
