Looks like my suspect was right: Kicking vmx_complete_interrupts out of vmx_vcpu_run makes -no-kvm-irqchip work again. Avi, could it be that 1c0f4f5011829dac96347b5f84ba37c2252e1e08 left do_interrupt_requests outdated behind? Or is vmx_complete_interrupts incorrectly queuing interrupts in the -no-kvm-irqchip case?
