unsync_child_bitmap takes one cacheline; the shadow page table takes 64. This will make unsync/resync much more expensive. I suggest to put unsync_child_bitmap at the end (together with unsync_children) and simply not allocate it when unneeded (have two kmem_caches for the two cases). -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
