[PATCH v9 00/84] VM introspection
The KVM introspection subsystem provides a facility for applications
running on the host or in a separate VM, to control the execution of
other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs,
MSRs etc.), alter the page access bits in the shadow page tables (only
for the hardware backed ones, eg. Intel's EPT) and receive notifications
when events of interest have taken place

[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
