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

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
