Most importantly to get the most out of nested hypervisors, you need 2 things:
1.) A processor that can handle EPT, or 'pDMA' 2.) A hypervisor that can passthrough a cpu using EPT(pDMA) <- this is needed to achieve hardware assisted virtualization(HAV) in the tier 1 guest. It is possible to nest with Para-Virtualization but you should not expect any form of 'usable' tier 2 guest instances. The overhead on the CPU by that point without pDMA is insane. When modeling something as complex as a cloud using nested virtualization, you really want HAV.
