Run an hypervisor inside an osx vm

Hello,

I am struggling to run any hypervisor (tried parallels, Vmware fusion and virtualbox) inside an OSX VM, in an unraid system based upon an AMD threadripper 3970x. I already enabled nested VMs and, at least VirtualBox, seems to run fine if I try the same within a Windows VM on the same system. Inside OSX, all those hypervisors, seem not to find nor VT-X and neither AMD-V (the latter is for Virtualbox). Is there any black magic based setting I am supposed to try? I saw Spaceinvader’s video on nested VM, I believe however he was running an Intel system and I am running a threadripper.

Thank you in advance for any help anybody can provide.

P.S. I know I created recently a post on the same topic, I hope I have learned enough to explain better what I was trying to achieve using the proper terminology. I am reposting by trying to apply to my situation the old:" If you want good answers you need to ask good question"
