Compared to previous kernel, IBRS/IBPB are not exposed anymore for use by KVM (MSR_IA32_SPEC_CTRL and MSR_IA32_PRED_CMD). VM running on the previous kernel (with a profile mandating spec-ctrl) won't be able to start anymore. -- You received this bug notification because you are a member of

As mentioned in #1742995, one patch is incomplete and doesn't expose the appropriate CPUID for KVM hosts when running on Intel hardware. 8339cae23d79be97a38df3852ef5dab870806a58 should add speculative control CPUID support for guests. The patch looks truncated as it defines KVM_CPUID_BIT_SPEC_CTRL

Hey! The patchset seems incomplete: 8339cae23d79be97a38df3852ef5dab870806a58 should add speculative control CPUID support for guests but only the AMD part is here. When running a guest on top of KVM, CPUID doesn't contain the spec-ctrl bit. I am using this patch instead:
