Hi,
Why is that a hypervisor, which alledgedly needs to be on physical hardware, can be deployed within a VM?
For example, XenServer (the actual hypervisor) can be deployed in an ESX VM?
Why is this possible (Although not a good idea for many reasons, but still works).
Also, why do people say a hypervisor needs physical hardware (from an architectural point of view, rather than obvious performance reasons).
Thanks
