What is your qemu command line?
The crash is in
int kvm_set_irq(struct kvm *kvm, int irq_source_id, u32 irq, int level)
{
struct kvm_kernel_irq_routing_entry *e, irq_set[KVM_NR_IRQCHIPS];
int ret = -1, i = 0;
struct kvm_irq_routing_table *irq_rt;
struct hlist_node *n;
trace_kvm_set_irq(irq, level, irq_source_id);
/* Not possible to detect if the guest uses the PIC or the
* IOAPIC. So set the bit in both. The guest will ignore
* writes to the unused one.
*/
rcu_read_lock();
irq_rt = rcu_dereference(kvm->irq_routing);
if (irq < irq_rt->nr_rt_entries)
^^^ here
hlist_for_each_entry(e, n, &irq_rt->map[irq], link)
irq_set[i++] = *e;
rcu_read_unlock();
Looks like kvm->irq_routing is corrupted (but not NULL).
