The architects of such a setup all too rarely pay attention to the security of their design. The widespread distribution of container technologies illustrates the low degree of protection under which many users are willing to work; however, you cannot assume that Linux hypervisors such as KVM are automatically secure simply because it's Linux and because virtualization inherently isolates its guests in a superior way compared with Docker containers, for example.
