Nested virtualization
    C6: not
    https://wiki.centos.org/HowTos/NestedVirt

        In some situations you would like to test or prove a
        Virtualization set-up before rolling it out on bare
        metal. In these cases the ideal scenario would be to set
        up your Hypervisor hosts as Virtual Machines and then run
        Virtual Machines on them. This scenario where you run
        VM's inside a VM is called nested virtualization. 

        Nested virtualization is a feature that can be enabled
        using a kernel parameter. Unfortunately, the current
        CentOS kernel does not support this parameter.
