peeper open faild code ：1

[demontop]

I found that I need to run peeper during the build, and then I built the peeper, but I didn’t see the peeper file after the build was completed. I tried to run the tester and found that the peeper open faild code: 1, I checked the source code and found that it was about /dev/shm Regarding, I don't quite understand how this part works, do I need to map the memory of the windos to the qemu vm? If so how to do it
