[libvirt] [PATCH 36/36] cpu_map: Introduce IA32_ARCH_CAPABILITIES MSR features

--- This should not be pushed yet as the QEMU interface for MSR features is not complete yet. If a domain with some MSR features enabled would be started, all of them would be marked as disabled in the live domain configuration (even though they were actually enabled by QEMU) and they would disappear during migration. src/cpu_map/x86_features.xml | 17 +++++++++++++++++ .../x86_64-cpuid-Core-i7-7600U-enabled.xml | 1 + .../x86_64-cpuid-Core-i7-7600U-json.xml | 1 +
