No idea if there's anything wrong with 2.6.27 itself. The KVM code in the 2.6.27 kernel is broken. qemu-kvm emits: KVM kernel module broken (DESTROY_MEMORY_REGION). Please upgrade to at least kernel 2.6.29 or recent kvm-kmod (see http://sourceforge.net/projects/kvm). You'll need to use newer kvm-kmod versions.
