Isn't by default PIT and PIC are initialized in Kernel? Is something more

You need KVM_CREATE_IRQCHIP and KVM_CREATE_PIT.
Also, I wonder if LAPIC need to be configured and initialized properly. I don't
want to use

Hi Guys,

I am using libkvm and believe it creates PIC and PIT by default.
I see kvm_create make calls to:-
1. kvm_arch_create function which indeed calls kvm_create_pit and KVM_CREATE_PIT
2. kvm_create_irqchip function and KVM_CREATE_IRQCHIP
It
or Timer ISR being called!

Thnaks,
So just programming of PIC (8259) should do the trick. Do I have to care about
IOAPIC or LAPIC programming? You mentioned lapic is disabled by default, what
about IOAPIC.
The ioapic will not have any vectors programmed so it will
