You either need to add it yourself, e.g. './x86-run ./x86/pmu.flat -cpu max' or use run_tests.sh, e.g. './run_tests.sh pmu'. standalone tests get their parameters from x86/unittests.cfg, which is why it's already using '-cpu max'. > ** > 2. intel_cet > gjiang@x1:~/source/kvm-unit-tests/tests> ./intel_cet > BUILD_HEAD=73d9d850 > *skip intel_cet (test kernel not present)* This error looks like x86/cet.c wasn't built. Maybe do a 'make clean' and 'make standalone' again and watch that cet.c doesn't fail to compile. > > Then I am not sure which test result should be correct, standalone test > or run all tests.
