Hello there!
Currently, I see the use of two cpu:
First: vboxmanage modifyvm "Name" - cpuidset 0x00000006 0x00000003 0x00000002 0x00000001 0x00000000.
Second: VBoxManage modifyvm "Name" --cpuidset 80000000000000 00000000 00000000.
Excuse me, what is the difference between the two? If so, what is the difference?

The second question: use - cpuidset this order, need to set these parameters CPUID it?
I use: "vboxmanage list hostcpuids" command to detect 25 cpuid; Not to create a complete cpuidset need to set up 25 cpuid information? If not, indicate the actual need to set all the CPUid information.

The third question: "vboxmanage setextradata" Name "VBoxInternal / CPUM / HostCPUID / 00000001 / ecx 0x1ED82203" This command and - cpuidset What is the difference? The need to set the number of cpuid, is not and "- cpuidset" " The same way

Looking forward to your reply.

You've been asking about the --cpu-profile command as well. I still don't understand what you want to do. And if you don't know what these are, or how they're supposed to work, you'd better leave it alone, or something is going to break.

What do you want to do?

Yes, I want to follow a different CPU model to test the software's virtual machine identification, whether to check out the current Guest environment.

I'm not sure I understand. Could you please give more details? A whole a lot more details? Explain the whole "project"...

You said earlier: "- cpu-profile" inside the CPU experimental template too little I do not know how to describe to you. My project is to want to use these commands to the Guest's CPU information to the whole Modeled to change, so Guest can not identify the real CPU information, so I want to know how to modify.

Look at it this way: If you can't bother explaining what exactly you're trying to achieve and why, then why should anyone bother helping you?
