The patch attached
enables the EPT feature. When present, it provides a
direct mechanism to
virtualize physical memory in HVM guests running on
processors with Intel(c)
Virtualization Technology.
We now use the EPT page
table as P2M (guest physical to machine
mapping), removing the
linear page table when EPT is used for the domain
(see the new file
p2m-ept.c). We did this by adding three operations in
the p2m_domain. If VT-d
is enabled, the EPT page table will be used as
the VT-d page table as
well (i.e. shared).
