So basically export a thin snapshot directly into tiny vm as container
rootfs? This is to allow writable rootfs? But this will also have the
issue of caching in each VM for same image. Am I missing something.
Well, we have this issue present even without VM. With namespced
containers also we have duplication of page cache on host for every
thin snaphost, so doing that duplication per vm does not lead to worse
results as compared to what we have today.
