I am using my old MacBook as a small server to run some docker containers. However I found a weird bug that I can't delete the directory after it has been mounted to a container. It shows resource busy, even can't deleted it in command line with rm -rf.
The reason is Docker Desktop default use VirtioFS with Vitrualization Framework. This thread will keep all files in the mounted directory open, so you can't delete it.
Just use gRPC Fuse instead of VirtioFS will solve this problem.
