For any non-released qemu, those capabilities are being re-generated, thus any modifications will be overwritten. > This is just for unit test, why not add the faking of SGX into that file. If > don't add faking of SGX into that file, the unit can not pass. You can add fake caps into any capabilities for already released qemu. Those are not being re-generated and thus any faked data will not be deleted.
