That's already there right? And your 1/2 patch was making toggling those bits easier. > (not now, later, for LXC to work) instead of enabling clearcpuid boot > option to mask CPUID features? IMO, the latter would look clearer. Yes, but for reasons noted earlier, you cannot tweak all hardware CPUID features as you want them. So, having a software-only layer of tweaking /proc/cpuinfo or something different you can come up with is the only option you have. And even in that case, applications running in the container which execute CPUID might fail in a strange manner when the corresponding /proc/cpuinfo flag was cleared by you intentionally but the hardware CPUID flag is there. In such situations, issues like that should probably be sorted on a case-by-case basis I guess. Thanks. -- Regards/Gruss, Boris.
