kvm_arch_load_regs() might load APIC base and APIC TPR from the uninitialized userspace APIC emulation.
This happened when running X11 on SMP guest in my case, disabling the APIC for vcpu3: vcpu not ready for apic_round_robin vcpu not ready for apic_round_robin vcpu not ready for apic_round_robin ...
