[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.

[RFC PATCH v1 00/34] VM introspection - EPT Views and Virtualization Exceptions
This patch series is based on the VM introspection patches
(https://lore.kernel.org/kvm/20200721210922.7646-1-alazar at bitdefender.com/),
extending the introspection API with EPT Views and Virtualization
Exceptions (#VE) support.
The purpose of this series is to get an initial feedback and to see if
we are on the right track, especially because the changes made to add
the EPT views are not small
