Chrome OS Flex is intended to run directly on the host device, not on top of some other OS. Chrome OS is basically a Chrome UI running on a customized Linux distribution, and most apps the target users would run are going to run directly in that environment - no "OS on your OS on your OS." The exception is native Linux apps, which on Chrome OS run in an LXC container inside a Chrome OS VM, mainly for security reasons. However, any GUI for such apps is proxied to the host display, so the virtualization is purely a back end detail - similar to how most web back ends run in containers and VMs on the internet somewhere.
