Title: KVM Architectural LBRs Status in linux package in Ubuntu: Incomplete Bug description: Architectural LBRs (Last Branch Records) Architectural LBRs (Last Branch Records) enable recording of software path history by logging taken branches and other control flow transfers within model-specific registers, and is inherited from legacy LBR. If CPUID.(EAX=07H, ECX=0):EDX[19] is set to 1, the processor supports Architectural LBRs. With VMCS support and XSAVE support, the KVM guests could also use ARCH LBR as well.
