There is a difference (at CPUID instruction level) between ignoring ECX value (leaf 1 for example) and requiring it to be set to 0. Looks like virCPUx86CPUID structure does not support this distinction though. Anyway I think it's better to include it there, will change to 0x00. -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
