The new MSR IA32_SPEC_CTRL MSR was introduced by a recent Intel microcode updated and can be used by OSes to mitigate CVE-2017-5715. Unfortunately we can't change the existing CPU models without breaking existing setups, so users need to explicitly update their VM configuration to use the new *-IBRS CPU model if they want to expose IBRS to guests. The new CPU models are simple copies of the existing CPU models, with just CPUID_7_0_EDX_SPEC_CTRL added and model_id updated. Backports commit 61efbbf869293f1deb9ee39d44bd4e635de59fa7 from qemu |
