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.
C7: maybe
