Can you also try with -no-kvm-irqchip?
You will need to comment out the lines
/* ISA IRQs map to GSI 1-1 except for IRQ0 which maps * to GSI 2. GSI maps to ioapic 1-1. This is not * the cleanest way of doing it but it should work. */
if (vector == 0) vector = 2;
in qemu/hw/apic.c (should also fix -no-kvm smp). This will change kvm wakeups to use signals rather than the in-kernel code, which may be buggy.
