[OpenIndiana-discuss] VirtualBox 6.1.18 nested vms

[russell]

Hi

Upon further investigation it is not the CPU or bios settings as 
hardware virtualisation is enabled it appears that while VirtualBox 
provide an environment  to install ESX 6.7.0u3 (which works with AMD 
virtualisation) it does not expose enough functionality for the ESX 
instance to run a VM. At the office I have access to a Dual AMD Epyc 
7302 server running ESX 6.7.0u3 and have run ESX 6.7.0 instances as VMs 
without a problem. The key Virtualisation difference between Epyc 7302 
and Ryzen 5600 is the Secure Memory encryption (encrypt all memory with 
a common key when enabled in the bios is transparent to any operating 
system) and Secure Encrypted Virtualisation (encrypt each VM with its 
own key).

The basic AMD-V while used by VirtualBox it does not appear to be 
exposed within the virtual machine so that ESX can use it.

Thanks
