How to run an Hyper-V host on a Windows Server 2008 R2 VM on ESXi?

I have a server with ESXi. One of the virtual Machines has a WinSrv 2008 R2 and I want to host Hyper-V on it.

First of all: is it possible? I keep being told that no, it is not, due to hardware requirements, namely hardware enabled virtualization开发者_Go百科 capabilities.

Second of all: if it is possible, how can I configure my VM to do so?

Thanks in advance!

Running a VM inside a VM is usually not possible due to hardware limitations. The exception is "pure emulation" implementation (like Bochs). But even when it is possible, it is not recommended due to severe performance degradation.

Hyper-V requires a CPU that supports hardware-assisted virtualization. Comercial hypervisors like ESXi do not emulate the CPU features that are required for Hyper-V.

ESXi have CPU features now.

I search also how to launch an hypervisor virtualbox (with features) inside ESXi with 2k8 host.
