No. It's a fairly common use case to i.e. virtualize several ESXi hypervisors underneath ESXi itself, in order to test clusters or other setups. VMWare calls the feature VHV, "virtual hardware-assisted virtualization". More generally, it's typically just "nested virtualization". It does look like it needs some CPU features, but which are now old enough to be essentially commodity.
(and yes, ESXi is a type 1 hypervisor--it's definitely something Microsoft could enable more broadly, instead of limiting the scope to Hyper-V nested setups)
- damnyou 7y agoIs it possible to run other hypervisors under Hyper-V as well? What about next to ESXi (as opposed to underneath it)? I'm learning a lot from this conversation, thanks.
- mappu 7y agoYou can run Hyper-V inside Hyper-V on Intel CPUs, but, not on AMD EPYC/Ryzen yet. (Not sure about nesting other hypervisors.)
- AdrianB1 7y agoYou are either in or under, not side by side. Yes, it is possible to run a hypervisor in a hypervisor, the limitation is usually in the parent hypervisor. In this particular case it would be useful to run side by side, but it is not possible and it also negates the idea of multiple hypervisors: why not have a single one running all the VM's?
