如果我的应用程序在虚拟机中运行,我如何检测(.NET或Win32)?
答案 0 :(得分:39)
这就是我使用的:
using (var searcher = new System.Management.ManagementObjectSearcher("Select * from Win32_ComputerSystem"))
{
using (var items = searcher.Get())
{
foreach (var item in items)
{
string manufacturer = item["Manufacturer"].ToString().ToLower();
if ((manufacturer == "microsoft corporation" && item["Model"].ToString().ToUpperInvariant().Contains("VIRTUAL"))
|| manufacturer.Contains("vmware")
|| item["Model"].ToString() == "VirtualBox")
{
return true;
}
}
}
}
return false;
编辑2014-12-02 :更新了代码,使其不再将Microsoft Surface Pro检测为VM。感谢Erik Funkenbusch指出这一点。
编辑2017-06-29 :更新了代码,以便它还会检查HypervisorPresent
属性的值。
编辑2018-02-05 :已删除对HypervisorPresent
属性的检查,因为它不正确。如果在超V服务器上的主机O / S上运行,则此属性可以返回true。

根据Virtual PC Guy的博文“Detecting Microsoft virtual machines”,您可以使用WMI检查主板的制造商。在PowerShell中:
(gwmi Win32_BaseBoard).Manufacturer -eq "Microsoft Corporation"

以下是一种方法的示例。它只适用于微软的Virtual PC和VMWare,但它是一个开始: http://www.codeproject.com/KB/system/VmDetect.aspx

Jay Abuzi在powershell中展示了解决方案。这与c#函数相同:
/// <summary>
/// Detect if this OS runs in a virtual machine
///
/// http://blogs.msdn.com/b/virtual_pc_guy/archive/2005/10/27/484479.aspx
///
/// Microsoft themselves say you can see that by looking at the motherboard via wmi
/// </summary>
/// <returns>false</returns> if it runs on a fysical machine
public bool DetectVirtualMachine()
{
bool result = false;
const string MICROSOFTCORPORATION ="microsoft corporation";
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2","SELECT * FROM Win32_BaseBoard");
foreach (ManagementObject queryObj in searcher.Get())
{
result = queryObj["Manufacturer"].ToString().ToLower() == MICROSOFTCORPORATION.ToLower();
}
return result;
}
catch (ManagementException ex)
{
return result;
}
}

此C函数将检测VM Guest OS: (在Windows上测试,使用Visual Studio编译)
#include <intrin.h>
bool isGuestOSVM()
{
unsigned int cpuInfo[4];
__cpuid((int*)cpuInfo,1);
return ((cpuInfo[2] >> 31) & 1) == 1;
}

我发现找出我的C#应用程序是否在vmware VM上运行的最简单方法是检查NIC卡的MAC地址。如果它是VMware VM,它将永远是:00:50:56:XX:YY:ZZ
您可以通过网卡枚举as resolved here.

public static bool isVirtualMachine()
{
const string MICROSOFTCORPORATION = "microsoft corporation";
const string VMWARE = "vmware";
foreach (var item in new ManagementObjectSearcher("Select * from Win32_ComputerSystem").Get())
{
string manufacturer = item["Manufacturer"].ToString().ToLower();
// Check the Manufacturer (eg: vmware, inc)
if (manufacturer.Contains(MICROSOFTCORPORATION) || manufacturer.Contains(VMWARE))
{
return true;
}
// Also, check the model (eg: VMware Virtual Platform)
if (item["Model"] != null)
{
string model = item["Model"].ToString().ToLower();
if (model.Contains(MICROSOFTCORPORATION) || model.Contains(VMWARE))
{
return true;
}
}
}
return false;
}

对于较低级别的测试,我建议查看ScoopyNG [1]。它是一系列已知的低水平,良好工作的vm检测方法,尽管有点过时了。
如果你真的想要依赖其他东西,比如已安装的工具(VM * Additions),那么这些更容易被假冒&#34;假的&#34;。
这篇[2]博客文章也有一个非常好的概述,从低级asm的东西,检查特定的DLL,文件路径和注册表项来检查。

此C ++代码将检测vmware产品,如express,esx,fusion或workstation
// VMWareDetector.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "windows.h"
#include <conio.h>
void CheckVM(void);
int main()
{
CheckVM();
_getch();
return 0;
}
void CheckVM(void)
{
unsigned int a, b;
__try {
__asm {
// save register values on the stack
push eax
push ebx
push ecx
push edx
// perform fingerprint
mov eax, 'VMXh' // VMware magic value (0x564D5868)
mov ecx, 0Ah // special version cmd (0x0a)
mov dx, 'VX' // special VMware I/O port (0x5658)
in eax, dx // special I/O cmd
mov a, ebx // data
mov b, ecx // data (eax gets also modified
// but will not be evaluated)
// restore register values from the stack
pop edx
pop ecx
pop ebx
pop eax
}
}
__except (EXCEPTION_EXECUTE_HANDLER) {}
printf("\n[+] Debug : [ a=%x ; b=%d ]\n\n", a, b);
if (a == 'VMXh') { // is the value equal to the VMware magic value?
printf("Result : VMware detected\nVersion : ");
if (b == 1)
printf("Express\n\n");
else if (b == 2)
printf("ESX\n\n");
else if (b == 3)
printf("GSX\n\n");
else if (b == 4)
printf("Workstation\n\n");
else
printf("unknown version\n\n");
}
else
printf("Result : Not Detected\n\n");
}

请记住,您不仅应该检查流行的VM模型,wmi的制造商名称,还应该检查现实与虚拟化之间的区别。
VM没有太多功能。
1)check-if-cpu-temperature-information-is-available
wmic /namespace:\\root\WMI path MSAcpi_ThermalZoneTemperature get CurrentTemperature
//On Real PC
//CurrentTemperature
//3147
//On VM
//Node - Admin
//Error:
//Description not supported
在vmware,virtualbox,Windows服务器,app.any.run沙箱上进行了测试。
2)Win32_PortConnector
Get-WmiObject Win32_PortConnector
//On Vm it is null
//On real pc it looks something like that
Tag : Port Connector 0
ConnectorType : {23, 3}
SerialNumber :
ExternalReferenceDesignator :
PortType : 2
