简介

记录如何解决虚机内软件、游戏启动报错：Sorry, This Application Cannot Run Under A Virtual Machine

关键点

虚拟化检测点可参考文档：操作系统能否知道自己处于虚拟机中?

CPU model and topology

  1. 禁用CPU的hypervisor功能。
  2. 使用host-passthrough模式，透传主机CPU能力。

参考xml相关配置：

1
2
3
4
5
6
7
8
9
...
<cpu mode='host-passthrough' check='none'>
  <topology sockets='2' cores='2' threads='2'/>
  <feature policy='disable' name='hypervisor'/>
  <numa>
    <cell id='0' cpus='0-7' memory='33554432' unit='KiB' memAccess='shared'/>
  </numa>
</cpu>
...

SMBIOS System Information

  1. 屏蔽透传给主机的底层系统信息，可修改为PC厂商的信息，或直接使用host模式。

参考xml相关配置：

1
2
3
4
5
6
...
<os>
  <smbios mode="host"/>
  ...
</os>
...

Windows系统内可通过systeminfo命令查看效果。

smbios mode为smbios时，系统内部可查看到的信息如下：

smbios-mode-smbios

smbios mode为host时，系统内部可查看到的信息如下：

smbios-mode-host

Hypervisor features

  1. 隐藏kvm特性。
  2. 若启用了hyperv，则需要隐藏hyperv的vendor_id。在未来，可能需要启用hyperv能力。

参考xml相关配置：

10
11
12
...
<features>
  ...
  <hyperv>
    <vendor_id state="on" value="1234567890ab"/>
  </hyperv>
  <kvm>
    <hidden state="on"/>
  </kvm>
  ...
</features>
