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, Nikos
