[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.
