[RFC PATCH v7 41/78] KVM: introspection: add KVMI_VM_CHECK_COMMAND and KVMI_VM_CHECK_EVENT
These commands can be used by the introspection tool to check what

(by userspace).
The introspection tool will get one of the following error codes:
* -KVM_ENOSYS (unsupported command/event)
* -KVM_PERM (disallowed command/event)
* -KVM_EINVAL (the padding space, used for future extensions,

[RFC PATCH v6 00/92] VM introspection
The KVM introspection subsystem provides a facility for applications running

(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
