Hi men, If there is an application who wants to detect what the OS is running on, physical hardware or Xen, can he do it like this: using SGDT to get GDT's address. If its address is 0xCxxxxxxx, then it's on physical hardware (the OS is Linux) If the address is 0xFxxxxxxx (0xFE820000), then it's on Xen. I test it, and it works. Can Xen do something to prevent this?
