编译之后会屏蔽looking-glass的IVSHMEM Device驱动，可有办法解决吗，谢谢

没用过这个软件，不清楚，但是vgpu肯定是不能用了，设备信息都带个v字，你直接大方承认自己是虚拟机就行了不用反检测。

行，谢谢啦

可能本问题和这个有关 https://github.com/zhaodice/qemu-anti-detection/issues/48

I'm having this problem too, it's not vgpu software, IVSHMEM (https://www.qemu.org/docs/master/system/devices/ivshmem.html) is for shared memory and looking glass uses it to copy the VM's screen to host machine for viewing. (like remote desktop but very very fast)

Is there no way to use ivshmem?

IVSHMEM is a special device from virtual machine that can be detectected so maybe I removed it?

Something about this section causes ivshmem to stop working.:

(LookingGlass's usage of ivshmem stops working, i'm not sure if ivshmem itself breaks)
