Hi,
I noticed recently NMI on guest kernel is not working well. host/guest
kernel is 2.6.39-rc4, and using vmx.
And test code is something like the following:
local_irq_disable();
for (i = 0; i < 10; i++) {
int cpu = get_cpu();
printk("%s: nmi %u, lapic %u\n", __FUNCTION__,
nmi_count(cpu), irq_stat[cpu].apic_timer_irqs);
mdelay(1000);
put_cpu();
}
the result is both of nmi and lapic are not increased. If I used
-no-kvm-irqchip, it works fine (increase nmi only). So, it seems to be
the bug of kvm driver side.
Ideas?
