Step-by-step: Installing ESXi as a virtual machine

Configure number of virtual CPUs, memory, network interfaces

The new virtual machine wizard will then prompt you to enter the number of virtual CPUs to assign, how much memory to provision, and how many network interfaces to assign to the virtual ESXi server. If any virtual machines of any significance are to be run on the virtual ESXi server, consider using 4 GB or more for the virtual machine's RAM configuration. Be sure to ensure that the LSI Logic Parallel option is selected for the disk controller.

Here is a tip that I use in my personal lab, for the virtual machines that are running on the virtual ESXi servers; I'm not too interested in what is running on those workloads. I'm more interested in vCenter features, ESXi configuration, cluster configuration, and other infrastructure features. I create a number of virtual machines that are very, very small. For example, many of them are 4 MB of RAM and are PXE boot virtual machines. These virtual machines are small and migrate very quickly with features such as vMotion. The only downside is that VMware Tools are not running on these virtual machines, so vSphere will not view the virtual machines as optimal. The resource savings are well worth it for testing purposes.
