As promised in v1 this series contains a few additional patches which limit usage of MSR features to QEMU that supports "unavailable-features" CPU property. This series intentionally enables MSR features for all QEMU versions before restricting the usage to make this restriction more visible in the test results. Version 2: - all but 2 patches from version 1 were pushed - 5 new patches Jiri Denemark (7): conf: Introduce virCPUDefCheckFeatures cpu_x86: Turn virCPUx86DataIteratorInit into a function cpu_x86: Introduce virCPUx86FeatureIsMSR cpu_x86: Read CPU features from IA32_ARCH_CAPABILITIES MSR cpu_map: Introduce IA32_ARCH_CAPABILITIES MSR features qemu: Forbid MSR features with old QEMU qemu: Drop MSR features from host-model with old QEMU src/conf/cpu_conf.c | 33 +++++++ src/conf/cpu_conf.h | 6 ++ src/cpu/cpu_x86.c | 96 +++++++++++++++++-- src/cpu/cpu_x86.h | 3 + src/cpu_map/x86_features.xml | 20 ++++ src/libvirt_private.syms | 2 + src/qemu/qemu_capabilities.c | 16 ++++ src/qemu/qemu_process.c | 29 +++++- .../x86_64-cpuid-Core-i7-7600U-enabled.xml | 1 + .../x86_64-cpuid-Core-i7-7600U-json.xml | 1 + ...86_64-cpuid-Xeon-Platinum-8268-enabled.xml | 1 + .../x86_64-cpuid-Xeon-Platinum-8268-guest.xml | 4 + .../x86_64-cpuid-Xeon-Platinum-8268-host.xml | 4 + .../x86_64-cpuid-Xeon-Platinum-8268-json.xml | 3 + .../qemu_4.1.0.x86_64.xml | 1 + 15 files changed, 207 insertions(+), 13 deletions(-) -- 2.22.0 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
