[Qemu-devel] org. cpuid passthru for qemu guest

[Holger Unterbrink (hunterbr)]

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
