Hi, A security guide for virtiofsd is now under review here:

https://gitlab.com/virtio-fs/qemu/merge_requests/6/diffs?commit_id=718c71fa4...

Comments welcome! I hope this will be useful to the Kata Containers community and early adopters of virtio-fs.

We will continue to enhance the sandboxing capabilities in virtiofsd to protect against guest escapes.

Stefan
