You can use 2.6.25/6 plus these three patches applied in order: http://kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.26-rc7/mmu-notifier-v18/list_del_init_rcu http://kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.26-rc7/mmu-notifier-v18/mm_take_all_locks http://kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.26-rc7/mmu-notifier-v18/mmu-notifier-core I posted the latest kvm-mmu-notifier patch on this list a few days before your question, that has to be applied to kvm.git. That's all. With the last patch I posted there are two issues pointed out by Marcelo, with largepages and with aliases but you won't risk to notice, I'm correcting those as I write this.
