(4) Finally the VM on nested ESXi can connect external network and ping to other virtual machines too. With virtual networking, you can network virtual machines in the same way that you do physical machines and can build complex networks within a single ESX Server host or across multiple ESX Server hosts, for production deployments or devel-opment and testing purposes. While this should happen in an order that makes sense (based on PCI bus numbering and/or MAC address increments) this does not always happen. This provides the traffic path for traffic entering and exiting the vSwitch. Copy the vDisk that matches the UUID from vm.
