Hi, is there any cmdline switch to hide virtualization to the guest OS ? Afaik qemu intercepts the cupid instruction (EAX=0x1) and always sets Bit 31 in ECX for virtualization ?

For malware analysis, I am trying to obfuscate as much as possible to the guest OS that it is running in a virtualized environment.
thx,
holger
