Requires a minimum of 4 GB of physical RAM (better 8 GB) Requires a minimum of 4 GB of physical RAM (better 8 GB). Hypervisor system requirements ComponentĪt least two CPU cores 64-bit x86 processors.Ī 64-bit processor with second-level address translation (SLAT). Nested virtualization is just one of the multiple technologies they both support on similar premises, which makes the comparison more than appropriate. Hyper-V and ESXi are “bare-metal” hypervisors. Such a vast disadvantage has almost led hosted hypervisors to extinction. Performance-wise, “bare-metal” hypervisors have the upper hand since they work directly on hardware and don’t waste its resources on maintaining VMs. To put it simple, the VMs won’t be running except on the user space of the host OS. Hypervisors of the second type – hosted hypervisors – need a host OS to provide virtualization services. Such a design allows for high reliability and security without compromising performance.

Hypervisors of the first type – “bare-metal” or embedded hypervisors – run directly on the hardware there’s no operating system (OS) between them and hardware.

Nested virtualization is a goldmine for homelabbers as it enables them to build virtualized platforms for home labs and small test environments that are limited on hardware. Nested virtualization is a relatively new technology which lets you create virtualized platforms inside VMs which themselves run on a hypervisor. 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. 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. Microsoft’s implementation of this technology is a bit different, but it exists. We all know that nested virtualization is not an ESXi-only feature Microsoft Hyper-V also enables us to run VMs inside its VMs.

Some time ago, I published articles on setting up a home lab using a PC running ESXi and Workstation.
