This patch series enables this feature to KVM guests. Here is a conclusion of the fundamental methods that we use: 1) the LBR feature is enabled per guest via QEMU setting of KVM_CAP_X86_GUEST_LBR;Did you send the QEMU parts for guest LBR support?
Not yet. Probably next week for the QEMU part. Best, Wei
