I had a host running kvm-27 oops on me last week. The system had been
up for about 2 weeks, and had probably run and stopped at least a couple
hundred kvm guests. I don't think it is very reproducible, but here it
is anyway. The host is running 2.6.20.4.
Here's the actual BUG_ON() that was hit:
static void *mmu_memory_cache_alloc(struct kvm_mmu_memory_cache *mc,
size_t size)
{
void *p;
BUG_ON(!mc->nobjs);
p = mc->objects[--mc->nobjs];
memset(p, 0, size);
return p;
}
There were several oopses in there, but I think probably on the first
one is of any real interest.
