Nested virtualization: VMware ESXi vs. Microsoft Hyper-V

Some time ago, I published articles on setting up a home lab using a PC running ESXi and Workstation. We all know that nested virtualization is not an ESXi-only feature; Microsoft Hyper-V also enables us to run VMs inside its VMs. Microsoft’s implementation of this technology is a bit different, but it exists. And, considering that VMware and Microsoft have been competing for a long time, it’s interesting to see what each has to offer for this type of virtualization. In this post, I examine how easy it is to configure a nested virtualization layer inside Hyper-V and vSphere VMs and discuss peculiarities of this process in both environments.
