[PATCH v1 0/4] Enable LBR for the guest
This patch series enables the Last Branch Recording feature for the
guest. Instead of trapping each LBR stack MSR access, the MSRs are
passthroughed to the guest. Those MSRs are switched (i.e. load and
saved) on VMExit and VMEntry.
Test:
Try "perf record -b ./test_program" on guest.

[RFC PATCH v6 00/92] 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 VM-s
(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
