Nested Virtualization
I have a Precision 5540 laptop running Ubuntu 20.10. I would like to enable nested virtualization but can't find any way to enable it in the BIOS.
Does anyone now of a way of doing this.
Note virtualization works fine, it's nested virtualization that doesn't work. I want to run an OpenStack devstack aio on the laptop as a VM and nested virtualization would help with running VMs inside that OpenStack. I have already tried CCTK/Dell Command Update Application without any luck.

@neillc There’s aren’t BIOS options specifically for nested virtualization. You need virtualization support, and then nested virtualization is enabled within the hypervisor itself or in cases like Windows Hyper-V on the specific VMs where you want to expose the necessarily capabilities for that VM to run a hypervisor within itself.
