For containers, the `rootfs/` directory contains a full file system tree of the root directory (`/`) in the container.
Virtual machines use a `rootfs.img` `qcow2` file instead of a `rootfs/` directory.

A split image consists of two files.
The first is a tarball containing the metadata and optionally the template files (usually `*.tar.xz`).
The second can be a tarball, `squashfs` or `qcow2` image containing the actual instance data.
The second is the root file system (container) or root disk (virtual machine).
For containers, the second file is most commonly a SquashFS-formatted file system tree, though it can also be a tarball of the same tree.
For virtual machines, the second file is always a `qcow2` formatted disk image.
