Nested ESXi 7 / 6.7 Networking error

I have been unable to load nested ESXi using the 2 latest versions of ESXi. I can get them to load the installer correctly, but 7.0 will not detect the network card, and 6.7 will detect the network card, but after installation it doesn’t pass any traffic. I’ve got all the pre-requisites done for nested virtualization, and i’ve tried setting the nic model to both e1000 and virtio and neither work. I’m using KVM as the hypervisor, not vCenter.
