Does VMware officially support nested virtualization in production environments with ESX 5.5?
This KB article implies VMware does not support it, but fails to mention ESXI 5.5:
VMware KB: Support for running ESXi/ESX as a nested virtualization solution
This document is kind of contradicting:
It says:
"Virtualized HV is fully supported for virtual hardware version 9 or 10 VMs on hosts that support Intel VT-x and EPT or AMD-V and RVI. To enable virtualized HV, select VM->Settings and navigate to the processor settings screen. Check the box next to "Virtualize Intel VT-x/EPT or AMD-V/RVI."
And a fe paragraphs down:
"ESX(i) may be used as a guest hypervisor to learn about VMware's server products, experiment with server setup, conduct training, show demos, and test configurations. VMware does not support running nested ESX(i) servers in production environments. Issues running ESX(i) in a nested configuration fall outside of VMware's Support and Service Level Agreements."
