[PATCH 0/5] KVM: nVMX: Enable nested apicv support.
In nested vmx, the efficiency of interrupt virtualization is very important, especially in high throughput scenes. This patch set enables nested apicv support, which makes a huge improvement in nested interrupt virtualization. I also have done some simple tests: L0: Intel Xeon E5-2630 v2 L1: CentOS 6.5 with 3.10.64-1.el6.elrepo.x86_64 kernel 16 vcpus, 32GB memory.
