[Virtio-fs] How to test virtiofs

[Vivek Goyal]

Hi All,

I recently noticed a regression with overlayfs on top virtiofs. I thought
that it will be good to put together a small text file which explains
how to test virtiofs to ensure its sanity. We can run these tests before
merging pathces in virtiofsd or in kernel.

For now this document is in my personal repo. I can move it somewhere
else if need be.

This is still work in progress and I will update it once I have got
more testing configurations working.

Any comment or feedback is welcome.

Thanks
Vivek
