[PATCH v3 0/4] Nested VMX: APIC-v related bug fixing
From: Yang Zhang <yang.z.zhang@Intel.com>
The following patches fix the issue that fail to boot L2 guest on APIC-v
available machine. The main problem is that with APIC-v, virtual interrupt inject
L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running,
L1 will detect interrupt through vmexit with reason external interrupt. If this happens,
we should update

[PATCH 00/11] Add virtual EPT support Xen.
From: Zhang Xiantao <xiantao.zhang@intel.com>
With virtual EPT support, L1 hyerpvisor can use EPT hardware
for L2 guest''s memory virtualization. In this way, L2 guest''s
performance can be improved sharply. According to our testing,
some benchmarks can show > 5x performance gain.
