Hi Mark and Norberto,
Mark, what do you need to virtualize and what your requirements are?
I think the question about virtualization is far too broad.
For example, you mentioned quotas. I think you can bypass storage
control problems, using seperate devices for each client filesystem.
Just create n vnode md(4) devices for your n jails. This has another
advantage besides partitioning storage. Since UFS supports sparse
files, only used blocks will occupy storage space, thus you don't
have to preallocate all storage.
HTH a bit,
