make clear a vmexit reason
Hi,
Lately I was puzzled by a vmexit reason 31 which was defined
as EXIT_REASON_MSR_READ
I allocated an array in xen data section and assigned its MFN to an EPT
entry of a domainU,
I thought the domU could access this array but after that the domainU
crashed
and xen gave me this exit reason "Bad vmexit (reason 31)"
But there is nothing to do with MSR READ, so I''m confused...

[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.
