检测是否是虚拟机

实验了下 vmware和xen 都检测出来了，各位喜欢XX的人可以试用下。 

不过现在的发行版喜欢默认安装xen，谁知道是不是honypot呢?

/*  gcc -Wall -o checkVM checkVM.c * check linux OS in VMare ?

#include <stdio.h>
 
struct idtr
{
  unsigned short limit;
  unsigned int base;
} __attribute__ ((packed));

unsigned int get_addr_idt()
{
  struct idtr idtr;
  asm("sidt %0" : "=m" (idtr));
  return idtr.base;
}

int main()
{
  unsigned int ptr_idt;
  ptr_idt=get_addr_idt();
  printf("IDT Addr %p \n",ptr_idt);
 
  if ( (ptr_idt>>24)==0xc0)
 printf("Real Linux\n");
  else
  printf("Maybe in VMare\n");
  return 0;
